A Comment on the Test Standards The SDL Atlas M233G AFC 45o Flame Chamber can be used to evaluate speci-mens according to several test standards including 16 Code of Federal Regulations (CFR) Part 1610 and ASTM D 1230. The preparation and testing of specimens may seem complex. Following are some operational guidelines, which may be help-ful in the preparation and testing of speci-mens. NOTE: This manual is not intended to re-place the user’s responsibility to conduct all tests using this instrument in accor-dance with all applicable standards. The user is encouraged to become fully ac-quainted with all test standards. There are special circumstances where test proce-dures as dictated by the standards are dif-ferent than what is presented herein. Follow the operation instructions in your SDL Atlas M233G AFC 45o Flame Cham-ber Instruction Manual. The main steps are briefly presented below along with some helpful TIPs. Install the instrument as directed in the Instruction Manual. Cut five test specimens. For plain surface fabric, FIRST define the fastest direction of burning:

Cut one test specimen 50 x 165 mm (2 in x 6 1/2 in) in each direction of the fabric, one from the length and one from the width. Place each specimen in a specimen holder, mount the holder, and apply the ignition flame. Whichever specimen burns the fastest is the direction in which all test specimens should be cut. Cut at least five test specimens.

TIP: When filling the glass “U”-shaped manometer with water, it is suggested that a syringe or eyedropper be used. A thin piece of flexible wire may be used to remove any bubbles that form during the filling process.

TIP: Although the test standard states the specimen size as 50 x 150 mm (2 in x 6 in), the holder will accommodate a length of 165 mm (6 1/2 in), which may make the mounting process a little easier.

TIP: Depending on the test results of five specimens, five additional test specimens may be needed. It might save time to cut ten specimens at the same time as the initial five specimens.

TIP: Plain surface fabrics, regardless of fiber type, weighing greater than 88 g/m2 (2.6 oz/yd2) are exempt from 16 CFR Part 1610. Apparel manufac-tured with the following fibers or blends of these fibers regardless of weight is exempt from the regulation: acrylic, nylon, polyester, mod-acrylic, olefin, and wool. Blends of these fibers with other non-exempt fibers are not exempt from the regulation.

TIP: It may be argued that 16 CFR Part 1610 is the critical standard for testing flammability performance of any apparel fabric. Although Consumer Product Safety Commission (CPSC) approval is not required for the use of alternate test procedures, CPSC does conformance testing according to the Flammable Fabrics Act (FFA), which requires testing according to 16 CFR Part 1610. If CPSC finds products fail 16 CFR Part 1610, the responsible party will be found in violation of the FFA. This is true even if the product passes an alternative standard.

SDL Atlas LLC offers this manual as a helpful guide to the user. The user should read the instrument Instruction Manual and all applicable testing standards. SDL Atlas, its subcontractors and representative agents are not responsible for the improper usage of this instrument as a result of this manual or any damages resulting from improper testing and reporting procedures on the part of any user. This includes non-conformance with any local regulations concerning health, safety, and pollution.

For raised surface fabric, cut test speci-mens in the direction of the raised surface. In other words, the nap, pile, or raised sur-face will run parallel to the 165-mm (6 1/2-in) length of the test specimen. Cut five or ten specimens. See the TIP above. Each specimen with a raised surface must be further prepared by brushing. A Brush-ing Device conforming to the requirements for this test is available from SDL Atlas. Mount the test specimen in the specimen holder. Mount the test specimen in the specimen holder. Make sure the lower edge of the test specimen is even with the lower edge of the holder. Use two to four small “Bull Dog” clips to hold the fabric specimen snugly in the specimen holder. Thin fabrics in particular may require four clips. If the test to be conducted is on the sec-ond set of specimens which have been subjected to drycleaning and wash proce-dures, the mounted specimens must be dried in an oven at 105 oC (221 oF) in a horizontal position for at least 30 minutes or until completely dry. When dry, the specimens must then be placed in a des-iccator for at least 15 minutes to 3 hours. The metal specimen holder will cool during this time. This is a good time to make sure your AFC Flame Chamber is operational. Verify the installation and setup process has been completed according to the AFC Instruc-tion Manual. Turn on the gas (use C.P. Grade Butane > 99.0% purity); make sure electric power to the instrument is on, and adjust the flame height to 16 mm (5/8 in). Thread the stop cord using 50/3 mercer-ized cotton thread through the thread guides on the specimen holder and on the right wall of the flame chamber. Tie a loop at the end of the thread and attach the weight to it.

Optional Brushing Device

TIP: Position the clips so the speci-men holder lies flat when placed in the testing position on the rack in the flame chamber. If the clips are too close to either end of the specimen holder, the holder will not lie flat. It must lie per-fectly flat to properly conduct the test.

TIP: Mercerized cotton thread can be found locally (try a local fabric or craft store) or contact SDL Atlas Customer Service for ordering information.

DO NOT USE POLYESTER-COATED THREAD. This is the type most com-monly available.

TIP: Attach the thread’s loop end to the weight in its well with the specimen rack in the retracted load position. The weight will be suspended when you move the rack to its test position.

3

If you thread the stop cord after the specimen rack has been positioned for testing, you may need to adjust the weight to a suspended position by rewinding some thread onto the spool. You also may need to adjust the weight to a suspended position if the fabric is so thick that no specimen rack adjustment from the re-tracted position is required. Make the weight adjustment by turning the spool counterclockwise to rewind some thread onto the spool. Be sure to tighten the wing nut on the thread spool after the weight is properly suspended. Placing the specimen holder in test position on the specimen rack. Place the specimen holder on the speci-men rack inside the test chamber. Use the lever to slide the rack into the test position. The tip of the inverted “L”-shaped arm should just come into contact with the face of the fabric test specimen. This will position the test specimen regardless of its thickness so that the burner tip will always be the same 8-mm (5/16-in) distance from the specimen. Conduct the test. Zero the timer. Turn main power switch to ON position. Toggle the main power switch to START position. Flame impingement will initiate and the timer will start automatically. Note for each specimen if the stop cord is broken (by the burning of the specimen) AND the burn time. The timer will stop automatically when the stop cord breaks and drops the weight into the microswitch well. Also note the burning characteristics for raised fabric specimens, including the number of ignitions or base burns, speci-men fusing, and surface flash. See TIP: What to Record on page 4.

TIP: Remember to retract the speci-men rack to the load position (to the right as you face the instrument) be-fore placing the holder in the rack. Do this by moving the lever located on the front of the chamber.

TIP: If specimens have been refur-bished (drycleaned and washed/dried), you must be ready to run the test at this point. The test method specifies that the test must start within 45 sec-onds from the time the specimen is removed from the desiccator.

TIP: Shut OFF the instrument’s main power switch before zeroing the timer.

TIP: Make sure the specimen is al-ready properly mounted as described above and the correct time of automatic flame impingement has been selected. For CFR 1610, this is one second.

TIP: WHAT TO RECORD

Below are some comments and acronyms that may help you to describe the burning behav-ior of a test specimen. For plain surface fabrics, the observations to be made during the test are simple. The mate-rial either burns or does not burn. Record the burn time and whether or not the cord is bro-ken.

DNI Did not ignite. IBE Ignited but extinguished. IBE* Ignited but extinguished. The burn goes under the cord without breaking it.

x.x seconds Actual burn time in tenths of a second until the cord is broken. For raised surface fabrics, the burning behavior can get more complex, and there are moreobservations required during the test. Surface flash occurs when the raised surface of thetest specimen burns very rapidly. Surface flash is equivalent to DNI for a plain surface fabric.A base burn occurs when the base fabric has ignited or the cloth substrate (the portion belowthe raised surface) burns. Both surface flash and base burning can occur during a test.

SFpoi Surface flash at point of impingement SFpw Surface flash part way. No time is shown. Flash did not reach the cord. SFuc Surface flash went under the cord but did not break it. x.x SFonly Time in seconds for surface flash to break cord. No damage to fabric. x.x seconds Actual time of burn from ignition until flame severs the cord.

No surface flash is observed. x.xSFBBpoi Time in seconds, surface flash and base burns at point of impingement

only. This is a nominal base burn. x.xSFBBpoi* Time in seconds, surface flash, base burns possibly at point of

impingement but the source of the base burn can not be determined. x.xSFBB Time in seconds, surface flash, base burn. Burning starts at points other

than point of impingement. A specimen report form can be found in the Appendix.

5

Define the number of specimens (five or ten) to be tested. The number of specimens to be tested for any fabric is determined by the number of broken cords and the average burn time for the first five test specimens. The TIP column shows the test results for plain and raised surface fabrics, which dictate test-ing of five additional specimens. Dryclean and wash specimens of the test fabric. This is the refurbish-ing step. The classification of fabrics as Class 1, 2, or 3 requires testing fabric specimens in their original or “as received” state and also after drycleaning and washing (refur-bishing). According to 16 CFR 1610, the dryclean procedure is done in a tumble jar with caustic potash. However, the 16 CFR 1610 procedure is banned by the EPA. ASTM D 1230 indicates coin operated or commercial drycleaning with amine sul-fonate. The drycleaning is followed by the AATCC 135 washing method or machine wash and tumble dry according to the garment label.

TIP: Please refer to the ASTM Flow Chart in the Appendix for help in de-termining classifications and exact test procedure.

TIP: Five additional test specimens are required if, and only if, the follow-ing test results are obtained: Plain surface One of five test specimens results in a broken cord AND the burn time is < 3.5 seconds. Two or more of the five test speci-mens result in a broken cord AND the average burn time is < 3.5 seconds. Raised surface One of five test specimens results in a broken cord AND the burn time is < 4.0 seconds AND there is one base burn. Two or more of the five test speci-mens result in broken cords AND the average burn time is < 4.0 seconds.

TIP: After refurbishing the speci-mens, repeat the initial screening test to determine the fastest direction of burning for plain fabric surfaces. Then proceed to test five, or if required, ten test specimens using the same procedure outlined above.

1.1 The M235 The M235 Abrasion and Pilling Tester is used to determine the abrasion and pilling resistance of all kinds of textile structures. Samples are rubbed against abradents at low pressures and the amount of pilling or abrasion is compared against standard parameters. For full details of the pilling test please see the separate pilling manual. 1.2 Features of the M235 The unique design of the M235 allows removal of individual sample holders for examination without lifting the top motion plate. The equipment is supplied with individual sample counters and pre determining batch totalisers. The equipment comes with all sample holders, a choice of loading weights and a pressing weight to ensure correct loading of the abradent fabric.

NOTE 1 The machine should be checked over a period of 5 minutes using a stopwatch. The counter should also be checked correctly to ensure it is functioning properly. NOTE 2 Parallelism should be measured using a dial gauge clamped in turn to each specimen bearing housing the machine should be switched on and the maximum and minimum readings taken from a dial gauge for each station. The circumferential parallelism of the test piece holder assembly when inserted into each station can be checked by means of the appropriate feeler gauges. 2.4 Calibration Checks If the M235 is being used on tests where end point is defined by a change in colour, then to ensure that the machine is correctly set, start the machine using a specimen of plain dark pigment printed fabric. Proceed for 7000 cycles then examine the specimen for colour change. If this is not even then the machine is not correctly set and the machine setting listed above should be checked. It is recommended that this is checked regularly depending on usage. If the laboratory is using broken ends or weight loss as the end point then two reference fabrics relevant to the work of the laboratory should be used at frequent intervals conducting the full test to the end point. If uneven wear is suggested between the testing positions or between machines the settings should be checked.

SECTION 3 INSTALLATION AND ASSEMBLY

3.1 Assembly for Abrasion Testing The machine is normally dis-assembled for shipping and should be re-assembled for abrasion testing as follows: 1. Place the M235 on a firm level bench. The machine has 4

adjustable feet to allow for levelling. 2. Ensure that the three bearing support blocks are correctly

positioned such that the total stroke is 60.5mm . The bearing support blocks should be in position 1 (see figure 1 below)

retaining screw figure 1 bearing support block in abrasion mode

If this is not the case, then the block is moved by first unscrewing the retaining screw with the aid of the hexagonal screw. Then lift and reposition the screw over the second peg. Finally replace and tighten the screw. retaining screw

3. Place the three metal balls (1) into the three cups (2) and lower the motion plate over the three bearings to rest on the three balls. The underside of the plate (3) is fitted with three steel

9

bearing plates and it is essential that the balls be placed directly between the cups and the steel bearing plates. It is also essential that the top motion plate is positioned correctly with respect to the casing of the machine.

4. Connect to the electricity supply with the cable provided. 3.2 Assembly for Pilling Testing 1. Place the machine on a firm and level bench. 2. Position the bearings on the inner and outer peg drive

wheels such that the total stroke of all the pegs is reduced to 24mm (see figure 2 below)

retaining screw figure 2 bearing support block in pilling mode This is achieved by moving the bearing support block to position 2(see figure 2). It is important to note that each block is numbered 1, 2 or 3. Each block must therefore be fitted to the corresponding numbered wheel drive.

3. Separate the spindles from the abrasion sample holders. 4. Push the long spindles into the pilling sample holders which

are alloy with a diameter of 90mm. 5. Place the three balls into the three cups and lower the

motion plate over the three bearings to rest on the three balls.

6. The underside of the motion plate is fitted with three steel

10

bearing plates and it is essential that the three steel balls are placed directly between the cups and the steel bearing plates.

7. Connect to the electricity supply with the cable supplied. 3.3Assembly for Linear Motion Testing Note: this configuration can only be used if the M235AC Linear motion Adaptor has been purchased. 1. For short stroke (24mm) length, position the bearings on the

outer 2 peg drives as for pilling testing ( see figure 2). 2. Position the linear motion adaptor on the centre peg drive

with the bearing above the locking nut ( see figure 3)

figure 3 bearing support blocks in linear motion mode

3. For long (60.5mm) stroke length, position the bearings on the 2 outer peg drives as for abrasion testing ( 3.1)

is different to the number which has already been performed, change the number on the total in the way previously described and then press the start button to continue.

7. After the test has been deemed to be finished, remove the samples from the specimen holders and mount on a piece of white card. Take a note of the number of rubs conducted to get to this end point.

8. Re set all the counters in the same way as described and carry on with the next test. The machine may be manually stopped at any time by pressing the stop button.

4.3 Preparation of apparatus, test specimens and conditioning. 4.3.1 preparation of apparatus 1. For conducting tests for abrasion according to:

BS5690 ISO 12947 BS3424 M&S P19 M&S P19B IWS TM 112 The abrasion table should be covered with a circle of felt which is either woven or non woven (non woven only for M&S testing). These felts are both available from SDL. The abrasion tables should then be covered with the standard abradent fabric. This should conform to ISO 12947 – 1 and is available from SDL.

2. For conducting tests for pilling, the abrasion table is first

covered with the standard felt as described above and then the tables are covered with a piece of the test specimen.

3. For testing for abrasion the specimen holders should be

loaded with firstly a piece of standard foam (available from

13

SDL) and then the sample under test. For testing for Pilling the sample holder is firstly covered with a piece of felt and then with the sample under test. 4.3.2 Conditioning All samples and standard fabrics should be conditioned in the standard atmosphere for testing All abrasion and pilling testing should be carried out in the standard atmosphere for testing: 20°C ±2°and 65% RH ± 2%.

14

SECTION 5 TESTING PROCEDURES

5.1 Sample preparation - Abrasion 1. After conditioning of the samples and standard fabrics, from

the test fabric cut 4,6, or 8 samples according to the capacity of the machine. These samples should be cut 38mm diameter this can be achieved using the M235A cutter. Cut the same number of samples out of the foam felt. From the standard abradent fabric cut the required number of samples (one for each station), these samples should be cut 140mm diameter. This can be achieved using the M235AB cutter.

2. Take one of the specimen holders, and unscrew the bottom of the holder which will reveal a brass nut, an insert and a holder.

3. Place the brass nut in the metal mounting device which is attached to the front of the machine.

4. Place one of the cut samples FACE DOWN in this nut. 5. Place one of the cut pieces of foam on top of this sample. 6. Place the metal insert on top of this with the flat side down. 7. Screw the holder back onto this arrangement ensuring that the

sample lies parallel, this will be achieved if pressure is applied while screwing the holder back together. Note the spindles supplied to test for abrasion are the shorter ones. Repeat this procedure for each abrading table.

NOTE: ALL THE PARTS FOR ONE ABRADING STATION ARE NUMBERED. IT IS ESSENTIAL THAT THE CORRECTLY NUMBERED PIECES ARE USED AT THE CORRECT ABRADING STATION. e.g ALL PIECES MARKED WITH THE NUMBER 1 SHOULD ALL BE ASSEMBLED TOGETHER AND USED AT STATION 1. 8. Remove the bearing housings from each abrading station by

unscrewing the nuts and lifting the bearing housing clear. 9. Remove the top motion plate from the machine to reveal the

abrading tables. 10. At each position in turn, unscrew the three nuts and remove the

clamping ring. 11. Lay a piece of cut felt, then a piece of cut abradant on each

15

table. 12. Put the pressing weight which is the large weight with the

handle on top of one of the tables and replace the clamping ring, ensuring that it is parallel to the machine.

13. Replace the three small nuts on the clamping ring. These nuts will be level with the top of the screws when the clamping ring is parallel. This is best achieved by gradually tightening each nut in turn until they are all level with the top of the screws.

Note : the felt can be used for until it becomes soiled or for 100,000 rubs whichever is the sooner. The abradent should be replaced after each test. The foam should be replaced after each test.

14. Once all the tables and specimen holders have been loaded,

lower the top plate back onto the machine, carefully locating the slots over the bearings.

15. Place each specimen holder in the appropriate hole and replace the bearing housing with the nut to secure.

16. Place the selected loading piece on top of the spindle (refer to the relevant standard)

17. After setting the counter according to the instructions in section 4, the machine can be switched on and testing can commence.

5.2 Sample preparation - Pilling (note: remember to adjust the machine settings if not already done) 1. After conditioning of the standard fabrics and the test

specimens, cut the required number of samples from the test specimen the samples should be 140mm diameter. Cut two sets of these discs, one for the pilling table and one set for the specimen holder.

2. Place the large block which comes with the pilling kit, small diameter uppermost on a table.

3. Place a rubber specimen holder ring around the outside of this device.

4. Place a 140mm disc of specimen on top of the loading device, allowing the excess material to drape over the edge.

5. Place a 90mm disc in the recessed top of the loading device. 6. Invert a specimen holder and place it on top of the felt. 7. Carefully roll the rubber ring up the loading block until it

16

locates in the groove. 8. Remove the specimen holder. 9. Note the spindles which are used for abrasion are the

shorter ones which are supplied and the spindles for pilling are the longer ones which are supplied.

10. To load the pilling tables, see table 1 to decide which abradent should be used or consult the relevant standard being tested to.

11. In both cases the procedure detailed in section 5.1 relating to abrading tables should be used.

12. Repeat this process for all specimen holders and abrading tables.

13.Ensure that all counters are reading zero then start the test. The method of assessing the end point will vary according to which standard is being tested to. The following methods are suggested methods only.

5.3 Test Procedure - Abrasion 1. Determination of specimen breakdown. Normally four specimens are tested, one in each of the abrading stations. Inspect the specimens at regular intervals without removing the specimens from the holders, A magnifying glass or microscope will normally be required for this examination. The end point is deemed to have been reached when the specimen has at least two threads broken in the test area. This should be carried out until all the specimens have reached this end point Report the individual results as well as the mean result. Replace the rubbed specimens in the holes on the mounted report sheet Note once a specimen has reached the end point it is not necessary to replace this holder for the continued running of the test. 2. Determination of Mass Loss See table 1 to determine at which intervals the mass loss should be determined.

17

Weigh all specimens before and after abrasion at each of the pre determined intervals. Draw a graph of no. of rubs against mass loss. (see also ISO 12947 part 3). For further details of the test method) TABLE 1 TEST SERIES NO. OF RUBS AT WHICH

The values in brackets should be agreed upon between the interested parties.

5. 3Test Procedure – Pilling Consult table 2 to determine which accessories should be used to conduct the Pilling test. Pairs of samples are rubbed together for periods which again vary according to the test method being used (see BS EN ISO 12945 for further details. Table 2 0.65kPa For woven and all

upholstery including (knitted) when following

Swiss pilling kit with pilling weight

0.25kPa For knitted fabric (excluding upholstery when testing to

Table 3 First pair 125 cycles Second pair 500cycles Third pair 2000 cycles

18

The three pairs of samples are used to provide examples of nil, slight and moderate levels of pilling required in the assessment procedure described below. When carrying out the test on the third pair it is important to stop the machine after every 5oo cycles and lightly brush away any loose fibres which may have gathered on the test surface. The degree of Pilling should be assessed using the following 5 point scale. 5 Zero or only very slight pilling 4 Slight pilling 3 Moderate pilling 2 Severe pilling 1 Very severe pilling When the appearance falls between two of the descriptions given above half values may be given. A set of photographs is also available from SDL which are mounted in an assessment viewer to enable the specimens to be more consistently rated.

19

SECTION 6 CALIBRATION AND MAINTENANCE

6.1 Calibration 1. The motion plate and abradent plate should be parallel.

Insert a dial gauge through the sample holder bearing and inch the top plate. The needle movement over the dial gauge should be within ±0.05mm over the whole surfaces of the abradent tables (with the abradent cloth removed).

2. Assemble each sample holder complete with the weight and place each one in position on the appropriate table. Use a feeler gauge to check for any gap between the face of the specimen holder and the table.

3. to adjust tables, slacken the central screw and adjust as appropriate using the three jacking screws located on the main deck plate. When complete, re tighten the central securing screw.

4. to adjust the motion plate, slacken the locking nut fitted to the stem of the three ball carrying cups rotate the cups to the correct height and re tighten the locking nuts.

6.2 Maintenance 1. The motion plate slides should be lightly smeared with

grease. 2. The ball cups should be lightly oiled as required. PLEAS CALL THE SDL ENGINEERING DEPARTMENT IF FURTHER INFORMATION REGARDING CALIBRATION OR MAINTENANCE IS REQUIRED.

INSTRUCTION MANUAL

FOR THE

M240X

C O N T E N T S SCOPE The SDL M240X Automatic PICK COUNTER is used for fast, convenient and accurate determination of the yarn density of woven fabrics and wire meshes as well as the loop density of knitted fabrics.

The instrument is suitable for both, measurements in the laboratory as well as mobile applications in the production environment. Since the instrument also works at moving test specimens, yarn density measurements can be taken directly at the running production machine or loom.

Its handy size and its ability to determine even extremely high thread densities, make the instrument a state-of-the-art alternative to the traditional pick glass and interference template. B. FUNCTION For testing, the face of the instrument is placed onto the test specimen. After manually entering the measuring range in which the test result is expected to fall, the start button is pressed. By means of a high quality lens system a narrow line of the test specimen is projected onto a linear CCD array. The signal from the CCD array is processed by a micro processor, and after less than a second the average yarn density of the test specimen is digitally displayed.

A special illumination system eliminates the interfering effects of colors and patterns. Therefore, even colored and patterned test specimens deliver a perfect test result.

The instrument can be calibrated and supplied with an ISO conform calibration certificate. Also supplied is a calibration card for instantaneous verification of the proper function and calibration as well as for re-calibration of the instrument.

Because of its small size and light weight design the instrument is perfectly suited for mobile use.

For stationary operation in the laboratory the instrument may be mounted to the optional FX 3250-MT Stand.

The instrument is equipped with a RS 232 data port. C. EVALUATION OF THE TEST RESULTS The simplest method for evaluation of the test results is to read the test results from the digital display, to write them down and to evaluate them manually.

Alternatively, the instrument can be connected to a PC. The test results are transmitted via cable into the PC for evaluation and documentation by means of the L 5110 Evaluation Program LABODATA III. This eliminates all reading, writing and calculating tasks and related errors.

The PC prints a comprehensive test report, including statistical analysis of the test results. In addition, it stores the test results on disk and performs long-term evaluations based on various selection criterions.

Multiple instruments of various types can be connected to the PC at the same time, and test

results from any other instrument can be manually entered through the keyboard into the PC. Test results from up to six data sources can be processed simultaneously and documented together. The Evaluation Program LABODATA III turns the PC into a complete data processing system for the testing laboratory.

The program can be operated in five different languages: English, German, French, Italian and Spanish.

L 5110 Evaluation Program LABODATA III for PC Program for statistical analysis, documentation, storage, and long-term evaluation of the test results from various TEXTEST instruments by means of an IBM compatible PC.

F. MEASURE 1. General remark: In spite of its name the FX 3250 PICK COUNTER is not a yarn

counter, but an instrument to measure distances. The instrument projects a thin line of the test specimen onto a linear CCD array and searches the signal of the sensor for recurrent distances, caused by the regular structures in the test specimen. Naturally, the instrument finds many different distances, from which the "correct" distance must be extracted. This is done by entering, prior to the measurement, a limited measuring range into the instrument, in which the test result is expected. Then, the instrument determines the dominating distance in the selected measuring range and converts it into the average yarn density, which is displayed.

This operating principle results in the following hints for operation:

• Selection of the correct measuring range is of utmost importance, because a wrong measuring range leads to a wrong test result!

• It is not necessary that all yarns are visible on the counting line of the instrument. Some of the yarns may be hidden or invisible. The minimum requirement for a reliable test result is, however, that the distances between the visible yarns are whole multiples of the "correct" yarn distance.

• The detected, recurrent structures of the test specimen may either be the individual yarns or groups of yarns ("repeats").

• In certain cases it may happen, that in the viewing field of the instrument a "wrong" distance appears more often than the "correct" distance. In these cases a wrong test result is displayed. Normally, such test results are marked with an *. In rare cases, however, this is not the case, and the operator must identify the wrong test result himself. The reverse may also happen, namely that for no good reason a correct test result is marked with an *. In this case simply repeat the test.

2. Conditioning: Prior to testing bring the test specimens to equilibrium with the standard

atmosphere of (20 ± 2) °C and (65 ± 2) % relative humidity according to ASTM D 1776 or DIN 53,802 respectively.

3. Switch on instrument: Briefly press any button to switch on the instrument. After a few

seconds the software version disappears from the display, and the instrument is ready for use.

4. Select test parameters: Briefly press the menu button "M" to start the menu function.

The letter "M" on the display signalizes that the menu function is on.

• Repeat: The repeat R blinks. With button "+" or "-" select the desired repeat.

Normally and preferably, a repeat of "1" is used. Only if a repeat of "1" fails to produce a reliable test result, the repeat of the test specimen must be entered:

• If the yarns are arranged in groups ("repeats") and the distances between the repeats are more even and better visible than the distances between the yarns, it is advisable to measure the repeat density rather than the yarn density. For that purpose the repeat R of the test specimen must be entered into the instrument, so that it "knows" that although it is to display the yarn density, it must look for the repeat density (which is R times lower).

• In multi-layer fabrics, containing n layers, each visible yarn is accompanied by one additional yarn in each layer. Therefore, the real yarn density is n-times higher than the visible yarn density. Therefore, the repeat R = n must be entered into the instrument.

• By means of the repeat the measuring range of the instrument can be extended to lower values. If, for example, a repeat of R = 2 is entered (although all yarns are visible) the instrument measures the number of yarns per 2 cm (or per 2 inches,

respectively). However, in the range under 8/cm (20/in) the measuring accuracy is limited. A yarn density under 3/cm (8/in) should not be measured.

Confirm your selection with the green button to start a test or with the menu button "M" to stay in the menu.

• Unit of measure: If you have pressed the menu button "M", the unit of measure blinks. With button "+" or "-" select the desired unit of measure: "1/cm" or "1/in".

Confirm your selection with the green button to start a test or with the menu button "M" to exit the menu.

5. Select measuring range: With button "+" or "-" select out of the 25 sub-measuring ranges the one in which the test result is to be expected. Important: A wrong measuring range leads to a wrong test result!

• When performing tests with a repeat of more than "1", select the measuring range based on the yarn density, not on the repeat density and not on the density of the visible yarns. (See paragraph F 4 "repeat").

• If the expected test result is located in the overlapping portion of two adjacent measuring ranges, select the higher of the two ranges.

• When measuring the course density of knitted fabrics, it is advisable to select the measuring range according to the (two times higher) yarn density and to divide the displayed test result by 2.

• If the expected test result is completely unknown, you may select the overall measuring range "8-300/cm" or "20-750/in", respectively. At test specimens with a simple construction this may lead to the correct test result.

• When testing rip-stop fabric, the instrument displays the density of the "inner" yarns. The "outer" rip-stop yarns are not accounted for.

6. Place instrument onto test specimen: Place the test specimen onto a flat surface.

Make sure the test specimen is free from tension and is not deformed. Set the bottom of the instrument onto the test specimen, so that it is properly lined up with the yarns of the test specimen. The marks on either side of the instrument indicate the position of the counting line. The instrument measures the density of the yarns running across this counting line.

When measuring extremely fine test specimens with a density over approximately 100/cm (250/in) precise alignment of the instrument is critical. Use the FX 3250-ARH Alignment aid.

If the test specimen is transparent, it is important that the surface of the test specimen support has no structure that could interfere with the pattern of the yarns in the test specimen and irritate the instrument. Also, the support should have a different color than the test specimen.

Since the instrument does not count, but instead measures distances between yarns, the test length does not influence the test result. Therefore, the test result is correct, even if only a portion of the test length is covered by the test specimen.

Since the actual test only takes a very short time, tests can also betaken at moving test specimens. However, the test specimen may only move in yarn direction and not faster than approximately 40 m/minute. Important: Avoid strong electrostatic fields, because they may damage the instrument!

7. Measure: Start the test by briefly pressing the green button. After less than one second

the instrument displays the average yarn density within the test length, rounded to three digits. Read and record the test result.

If the instrument is connected to a PC with the L 5110 Evaluation Program LABODATA III, press the ENTER key of the PC to transfer the test result to the computer.

8. Warning signals: The instrument automatically monitors the reliability of the test results

and marks doubtful test results with an alarm sign. The same sign also appears on the test report generated by the L 5110 Evaluation Program LABODATA III:

"*" Uncertain test result: Due to poor recognition of the yarn density the test result is uncertain. Such test results should only be used if they are plausible or if they have been visually verified. Repeat the test.

"o" Limited measuring accuracy: The measuring accuracy of the test result is ± 0.2/cm x R (± 0.5/in x R) instead of ± 1 % of the displayed value, because the actually detected density is less than 8/cm (20/in). If a repeat of more than "1" has been selected, try a repeat of "1".

9. Statistical analysis and test report: Statistically analyze the test results, and prepare a

test report.

If the instrument is connected to a PC with the L 5110 Evaluation Program LABODATA III, the test results are continuously statistically analyzed, and at the end of each series of tests, a comprehensive, standard conform hard copy test report is printed.

10. Switch off instrument: The instrument is switched off automatically. The switch off time

is approximately 25 s after the last use, when operated with batteries and approximately 3 minutes after the last use when operated with the power adapter.

G. CALIBRATE From time to time check the calibration of the instrument by means of the calibration card supplied with the instrument. If necessary, re-calibrate the instrument: 1. Switch on instrument: Briefly press any button to switch on the instrument. After a few

seconds the software version disappears from the display, and the instrument is ready for use.

2. Select test parameters: Briefly press the menu button "M" to start the menu function.

From the menu select the following test parameters in accordance with paragraph F 3:

• Repeat: 1 • Unit of measure: "1/cm".

3. Select measuring range: With button "+" or "-" select the measuring range "227 -

300/cm". 4. Position instrument: Place the instrument onto the calibration card, so that the edges of

the instrument line up with the edges of the calibration card. 5. Measure: Start the test by briefly pressing the green button. 6. Check display: Compare the displayed test result with the face value of the calibration

card (250/cm).

If the displayed test result is equal to the face value of the calibration card, the instrument is perfectly calibrated and no re-calibration is required. In this case proceed with paragraph G 11.

If the displayed test result differs from the face value of the calibration card, the instrument needs re-calibration. In this case proceed with paragraph G 7.

7. Start calibration program: Start the calibration program by simultaneously pressing the

buttons "+" and "-" for three seconds. The letter "C" on the display signalizes that the calibration function is on.

8. Correct calibration: By means of the button "+" or "-", respectively correct the displayed

test result until it is equal to the face value of the calibration card (250/cm). 9. Check sharpness: In the upper right corner of the display a three-digit number is

displayed, which is a measure for the sharpness of the lens system. This number can be very helpful in locating the problem should the instrument malfunction.

10. Terminate calibration program: Terminate the calibration program by simultaneously

pressing the buttons "+" and "-" for three seconds. The calibration program is terminated when the letter "C" disappears from the display.

11. The instrument is now ready for use.

H. HINTS FOR TROUBLE SHOOTING • Problem: The display blinks, the test procedure is interrupted, the test result "000" is

displayed or the instrument cannot be switched on.

Possible cause: The batteries are exhausted.

Solution: Replace the batteries by two new size AA batteries. Do not use rechargeable batteries!

The batteries are located in the battery compartment at the front of the instrument. To change the batteries, pull out the battery compartment cover. First remove the upper battery by slightly pushing it to the right, against the contact spring. Afterwards removal of the lower battery is easy. Make sure to insert the batteries in the correct orientation which is shown at the bottom of the battery compartment.

• Problem: The instrument displays an obviously wrong test result.

Possible cause: A wrong measuring range has been selected.

Solution: Select the measuring range so that the expected test result falls into the measuring range. A wrong measuring range leads to a wrong test result!

If a repeat of more than "1" has been selected, select the measuring range based on the yarn density, not on the repeat density. For more information consult chapter H.

Possible cause: A wrong repeat has been selected.

Solution: Select the correct repeat.

Normally and preferably, a repeat of "1" is used. For exceptions see paragraph F 4. • Problem: The instrument no longer produces test results.

Possible cause: The micro processor has crashed. This may happen in particular when the instrument is exposed to strong electrostatic fields, for example when measurements are taken on the moving fabric in the production machine.

Solution: Open the battery compartment and remove one of the batteries for a few seconds. After the battery has been re-inserted the instrument should resume operation. If this is not the case, the electronic circuit is defective. In this case return the instrument to Textest for repair.

I. MAINTENANCE The SDL M240X PICK COUNTER requires no maintenance. Just make sure, that the glass window at the front of the instrument is kept clean and that it is not scratched. For cleaning of the glass window or housing use spirit only, no solvents!

J. DATA PORT The SDL M240X Automatic PICK COUNTER is equipped with a bi-directional, asynchronous RS 232 data port for transmission of the test results to an external computer.

The character code is ASCII, with 1 start bit, 8 data bits and 2 stop bits, without parity and without protocol. The baud rate is 9,600 baud.

The pin layout of the 3-pin connector at the side of the instrument is: • pin "center": request for data RD • pin "tip": data line TD • pin "end": ground.

When the instrument receives a "CR" character (Hexadecimal "0D") as request for data through pin "center" of the data port, a 60 character ASCII string is transmitted through pin "tip". The format of this string is as follows:

SC II II II II II II II SN SN SN M VP1 VP1 VP1 VP1 VP1

VP1 UP1 VP2 VP2 VP2 VP2 VP2 VP2 UP2 VP3 VP3 VP3 VP3 VP3 VP3 UP3 VP4

The instrument is equipped with a series of replaceable blades and when the safety catch is released slight pressure on the hand wheel brings the blades in contact with the material. The specimens are cut out by rotating the hand-wheel under pressure. The weight of the instrument, and the surface finish of those parts in contact with the material are such that the specimens are always removed cleanly and have smooth edges.

SECTION 2 OPERATION AND MAINTENANCE

2.1 Method of Operation With the specimen on the special mat, place the cutter over the area to be cut. Pull out the safety catch (B) and, whilst applying pressure, turn the hand wheel 90 - 100 degrees. It is important to only apply sufficient pressure to cut the fabric, beacause if too much pressure is applied it will lead to the cutting mat being damaged. Lift the cutter and the specimen will remove cleanly, and with smooth edges, from the original fabric 2.2 Maintenance Instructions. The instrument requires no special maintenance, but the following is advised: • Protect the surface from dust and dirt. • Protect the edges of blades and surface of the internal pressure

plate. • After the cutting procedure it is recommended to lift the pressure

plate and blades holder in the upper position. 2.3 Replacing the Blades - M235 AB, 236A, 236C, 236E The blades (F) can be replaced by those supplied, further supplies can be obtained from SDL (SDL 236F). Please note: when ordering replacement blades, quote the model number, located on the front of this manual, as the specification for each model's blades are different.

M236 Page 6

If the blade edges are worn, they can be reversed, and eventually replaced with new blades. For reversing or replacing the blades the following procedure applies: 1. Turn the Blade holder (D) into the gap position of the external

casing. 2. Unscrew the screws (H) that secure the holding plate (D) and

remove the plate. 3. Reverse or replace the blade, using the small screws to locate

the blade in the correct position. 4. Replace the holding plate and secure. 5. Repeat for each blade. 2.4 Replacing the Blades - M235A, 236B (See figure 3) 1. Undo the screw in the internal pressure plate. 2. Remove the internal pressure plate - taking care not to misplace

the spring which sit on the spindle. 3. Unscrew the grub screw with a small wrench. 4. Withdraw the top part of the casing to expose the blade clamp. 5. Proceed as from section 2.3, step 3.

1.0 INTRODUCTION SDL Atlas Scorch Testers (M247) provide controlled conditions of temperature and pressure according to AAATC and ISO instrument requirements for testing potential damage due to chlo-rine retention and colorfastness to hot pressing and to dry heat (sublimation). The Scorch Tester consists of one set of heated plates with their own low density cartridge hea-ter to ensure constant temperature during repeated tests. The lower plate is set in a fixed posi-tion in the base of the instrument. The upper plate is mounted in a hinged head that may be raised to permit the loading or removal of specimens. The various tests for the Scorch Tester specify temperatures that range from 110 °C to 210 °C (230 °F to 410 °F). A selector switch allows the operator to read the temperature of each plate individually. The Scorch Tester’s head rests on four spring-loaded pins that counterbalance a percentage of the head weight and plate pressure on the specimen, conforming to chlorine retention test me-thods. To test a material’s colorfastness to heat, the spring-loaded pins can be easily disengaged to allow the full weight of the head to rest on the specimen. For hot pressing methods, the opera-tor simply covers the bottom plate with an optional heat resistant flexboard sheet, wool flannel and undyed cloth.

2.0 SAFETY This section introduces safety symbols that will appear throughout this manual and are affixed to the instrument. It also provides a list of precautions and guidelines to operate the Scorch Tester safely. Please read the manual thoroughly before setting up and operating your instrument. 2.1 Safety Symbols

4.0 INSTALLATION 4.1 Unpacking the Instrument Inspect the carton for damage that may have occurred during shipping. Carefully unpack the Scorch Tester and remove the packing foam and plastic ties that secured it during shipping. Ve-rify that the instrument was shipped in good condition and refer to the shipping list to be certain that you have received all the parts ordered. Report any equipment damages to the carrier and/or shortages to SDL Atlas Customer Service. 4.2 Setup After unpacking the instrument, place it on a smooth level surface. The room in which you place the instrument should be well ventilated with minimal drafts and a low level of airborne particulates. Do not install the instrument in a toxic environment. Connect the electrical power cord at the back of the instrument into the proper power outlet. 5.0 CONTROLS On/Off Switch and Indicator Light: When the ON/OFF switch is in the ON position, power will be applied to the instrument. The Indicator Light is a visual signal that power is applied and the Scorch Tester is hot. Temperature Control: The Scorch Tester utilizes one solid-state electronic thermostat capable of accurately maintain-ing a temperature range of 110 to 230 °C (230 to 440 °F). The thermostat dial has a white circular area around the temperature pointer knob, which can be marked by the operator to the various temperatures to which tests will be run. (See Section 6.0 for details). When the dial is in the minimum position (extreme counterclockwise position) the thermostat will bring the heater up to approximately 100 °C (212 °F). When in the maximum position (extreme clockwise position), the thermostat will bring the heater up to approximately 232 °C (450 °F).

Scorch Tester

Doc. P/N 08103800 5 Rev. 1.0

5.0 CONTROLS (continued) Temperature Indicator: A 0–250 °C (0–500 °F) pyrometer indicates temperature. It is used in conjunction with the UPPER/LOWER selector switch so that you can monitor the heated plates. The pyrometer has been calibrated at the factory and therefore further adjustment is not required. UPPER/LOWER Selector Switch: This is a toggle switch that connects the thermocouple leads from the plates to the pyrometer. It will enable you to check, not only the temperature spread between pairs of heaters but also the temperature of each individual heating surface. When in the UPPER position, it will connect the thermocouple from the upper block to the pyrometer. When in the LOWER position, it will con-nect the lower heater thermocouple to the pyrometer. HEATING Indicator Light: The HEATING indicator light indicates when voltage is applied to the heaters. A steady light indicates that the thermostat is calling for heat. A pulsing light indicates that the temperature is stabilized and the thermostat is controlling the temperature set point.

6.0 OPERATING PROCEDURE Before starting your test, verify that the Scorch Tester is connected to a properly grounded receptacle.

Never touch the heated upper plate or burn injuries may result. Al-ways use the handle to raise and lower the upper plate.

6.1 Setting Test Conditions The upper plate should be in the closed position (resting on the lower plate) before you set the test conditions. 1. Push the toggle switch to the ON position with the head of the Scorch Tester down and the

two heating plates in contact with each other.

2. Turn the temperature knob to a point about one-half the range of the dial. Note that the py-rometer will rise to some temperature. Adjust the knob to the test temperature between 110 and 230 °C (230 and 440 °F).

With the thermostat set to the minimum position, the plates will heat up to approximately 100 °C (212 °F). When the dial is set to the mid-point on the reference scale the plates will be heated to approximately 160 °C (310 °F).

3. A steady heating light indicates that power has been applied to the heater. When the light

pulses steadily (the ON and OFF time being equal) the heater has reached the temperature that the thermostat is set. Check the pyrometer for proper temperature and readjust ther-mostat as required.

4. Turn the UPPER/LOWER selector switch to the LOWER position. This will connect the py-rometer and the heating indicator light to the bottom heater plate.

5. Recheck the temperature and make adjustments as required. Check both the UPPER and

LOWER positions. Any large temperature difference between the upper and lower plates would indicate a malfunction that must be corrected before the test can be conducted.

6. Mark the test temperature for your test on the white circular area around the temperature

pointer knob.

7. When the set temperature is reached, place your prepared specimens between the plates and follow the applicable test procedure.

Do not allow the upper plate to fall forcefully on the bottom plate.

6.2 Colorfastness to Heat When operating the Scorch Tester to comply with colorfastness to heat and hot pressing me-thods, which require the full weight of the upper head, the four spring-loaded pins should be care-fully disengaged. Push each pin down through the top surface of the instrument base and move it slightly to one side so that it is held against the underside of the base surface. When this test has been finished, the spring-loaded pins can be easily engaged by using a pointed object to move each pin from the underside of the base surface. When the pins are in their normal positions, they will again support the upper head assembly for retained chlorine test methods requiring that the weight of the head be counterbalanced. 7.0 MAINTENANCE Keep the heating plates clean by wiping with a soft cloth and isopropyl alcohol. Verify that the upper and lower plates are uniformly in contact at all points. The four spring-loaded pins supporting the upper head were adjusted at the factory to provide a uniform weight distribution over the entire surface of the lower plate. The pins relieve all but 255 g (9 oz) of the weight of the upper head on the Model SO-3B and all but 1420 g (50 oz) on the Model SO-5B. Verify the pressure of the upper head by using a spring scale to measure the weight of the head when a gap is opened between the heater plates. If readjustment is neces-sary, turn the instrument on its side and turn the hex socket screws on the underside of the in-strument in a clockwise direction to increase and in a counterclockwise direction to decrease the spring tension.

SECTION 2 UNPACKING AND SETTING UP

2.1 Installation

Remove the instrument carefully from the case.

Screw the base (1) over the bottom of the main bar (2) of the instrument locking the nut so that the two feet of the base with the adjusting screws (4) will be at the front.

Put the instrument on a table having about 50cms height and level

it(3) by the adjusting screws.

Fix the instrument to the table by the screws.

At this [point take away the last cords that tie up the instrument and after disconnecting the lever (5) of the pendulum (6) ensure that it’s pointer remains on zero of the quadrant.- otherwise adjust the screws until the pointer is exactly zero.

Fill the cylinder (9) with the oil supplied. To make this operation

easier lift up the traction system (10) with the handle (11).

Lift up the system until it connects with the trigger (12). At this point the instrument is ready to be used for testing.

SECTION 3 TEST PROCEDURE

Lock the clamp (13) with the lever (14). Fix the yarn into the top clamp and into the bottom clamp (15) with light tension.

Apply the counter weight(16) to the pendulum according to the scale :

If you use no counterweight you should read the result off the 0-500 scale. If you use the 3000 g weight you should read the result off the 0-3000 scale. If you use the 6000 g weight you should double the result off the 0-3000 scale.

Disconnect the pendulum from the stop position with the lever (16).

Disconnect the lever (12) that holds up the traction system. At this point the bottom clamp will start going down. The speed can be adjusted with the small lever (17) that determines the moving of the pointer (7) on the quadrant scale (18). Both pointers will lock at the breakage of the yarn.

Read the loading value on the scale (8) and the elongation on the

index.

Set the quadrant to zero by lowering the lever (20).

Set the traction system to the initial position, lock the top clamp, remove the sample which has been tested. lock the pendulum with the special clamp and put the yarn in the clamps. At this time the instrument is ready for the next test.

Recommendations for Surround

GretagMacbeth SpectraLight III is designed for critical color evaluation and therefore it is important that precautions betaken to ensure the best environment for this purpose.• Viewing booth installations provide an area which is manufactured in conformance with ASTM standards. The work

surface and surround area of view are neutral in color and low in gloss. The opening of the booth should face an area that provides the least interference from ambient light (natural or artificial).

• Overhead luminaire installations require the user to develop a controlled viewing environment. Contamination from other light sources can minimize the effectiveness of a standardized source, so the evaluation area should always be shielded from ambient light (natural or artificial). The best location for an overhead luminaire is in a windowless room with no interference from other light sources. If these conditions are not available, light-tight curtains should be selected, a viewing booth should be constructed, or an enclosing curtain should be used. The Luminaire should be installed no closer than 2 feet to the nearest walls to minimize light level uniformity problems. To avoid color misjudgments, the background on which the sample is placed and the surrounding area of view should be neutral in color and have a low gloss. It is typically recommended that Munsell N7/ is used.

• White backgrounds are recommended when evaluating low gloss or light color samples, gray backgrounds are recommended when evaluating medium gloss of intermediate color samples, and matte or flat black backgrounds are recommended when evaluating high gloss or dark color samples.

Viewing Booth Installation

Note: To ensure adequate support and space for the unit, see “SPECIFICATIONS” on page 1.1. Move the viewing booth shipping container to the general area that the booth is to be used. Be sure to allow for

sufficient room for assembly (approximately 10 ft x 10 ft area is recommended).

2. Carefully unpack and remove the viewing booth components from the shipping containers. Carefully examineeach shipping container for contents before discarding it.

WRINKLE RECOVERY TESTER

SERIAL NUMBER___________

DATE___/___/___

2


1.1 General The M272 is a simple device which can be used to determine a fabric’s ability to recover after wrinkling under a pre-determined load for a set period of time. A set of plastic replicas is available which are graded 1-5 to give values for specimens according to AATCC 128 and ISO 9867. 1.2 Apparatus ∗ Wrinkle recovery tester. ∗ Three dimensional replicas (if ordered) ∗ Three weights.(total 3500g). ∗ Also required : clothes hanger with clips (not provided). ∗ Viewing area according to figure 1 (not provided). 1.3 Unpacking and installation Carefully unpack the instrument and check for any damage which may have been caused in transit. In the unlikely event of anything being missing or damaged please contact the Customer service manager at the address below :

1.4 Installation The instrument should be sited in an air conditioned room with the following conditions : For testing to AATCC 128 : 21 ± 1°C and 65 ± 2% RH. For testing to ISO 9867 : 20 ± 2°C and 65 ± 2% RH.

Note these are the conditions necessary for both conditioning and testing.

4

SECTION 2 TEST PROCEDURE

2.1 Specimen preparation. ∗ Cut three specimens each measuring 150mm x 280mm. These should

be cut with the long direction running in the warp or the wale direction of the fabric. Note cut the specimens from a wrinkle free area of the specimen. Note if no wrinkle free areas are present it is permissible to press the specimen lightly with a steam iron.

∗ Pre condition each specimen for a minimum of 8 hours in the conditioned atmosphere.

2.2 Procedure ∗ Raise the top flange of the recovery tester and hold in position with

the locking pin provided. ∗ Wrap one long edge (i.e the 280mm side) of a pre-conditioned test

specimen around the top flange of the wrinkle tester, with the face of the specimen on the outside.

∗ Fasten the specimen in position using one of the strips of Velcro. ∗ Arrange the bottom ends of the specimen so that they lie opposite the

top ends. ∗ Wrap the second piece of Velcro around the bottom of the specimen

so that it forms a “closed tube” of fabric. ∗ Adjust the specimen by pulling on its bottom edge so that it lies

smooth without sagging between the top and bottom flanges. ∗ Withdraw the locking pin and lower the top flange gently with one

hand until it comes to rest. ∗ Immediately place a total mass of 3500 grams (all three weights) on

the top flange and record the time. ∗ After 20 minutes, remove the three weights and raise the top flange,

carefully avoiding altering any of the induced wrinkling. ∗ With a minimum of handling, place one of the shorter of the sides

under the clips on the hanger and allow the specimen to hang vertically.

∗ After 24 hours in this conditioned atmosphere, gently remove the hanger with the specimen to the viewing area.

5

SECTION 3 EVALUATION

3.1 Timing ∗ Three people are required to independently rate each specimen. ∗ Note that a minimum time should elapse between these three

observations being taken to minimise the specimen recovering to different extents.

3.2 Mounting Mount the specimen on the viewing board as illustrated in figure 1, with the warp or wale direction hanging vertically. Place replicas on each side of the test specimen to facilitate comparative rating. Mount the replicas 1, 3 or 5 on the left-hand side and 2 or 4 on the right hand side. The over head fluorescent light shall be the only light source for the viewing board, all other lights shall be switched off. It is recommended that the viewing area is in a curtained off area as it has been found that reflections off walls etc can affect the results. The observer shall stand 1.22m away from the bottom of the front of the board. Assign the number of the replica, which most nearly matches the appearance of the test specimen. (See table 1) The observer independently rates the other two specimens. The other two observers should carry out the same procedure. 3.3 Expression of Results Calculate the average of the nine observations for each sample and express to the nearest ½ rating for ISO, to the nearest 1/10 rating for AATCC.

6

3.4 Test Report The test report shall include the following information: The standard used to test to The average of the nine observations. The conditioning atmosphere used for testing. NOTE : FOR SPECIFIC DETAILS ABOUT TESTING TO AATCC 128 OR ISO 9867 PLEASE REFER TO THE TEST METHOD BEING USED.

SECTION 1 INTRODUCTION 1.1 Operating Principle The material to be cut is placed between the cutter and the mat. The instrument is equipped with a series of replaceable blades and when the safety catch is released slight pressure on the hand wheel brings the blades in contact with the material. The specimens are cut out by rotating the hand-wheel under pressure. The weight of the instrument, and the surface finish of those parts in contact with the material are such that the specimens are always removed cleanly and have smooth edges.

SECTION 2 OPERATION AND MAINTENANCE

2.1 Method of Operation With the specimen on the special mat, place the cutter over the area to be cut. Pull out the safety catch (B) and, whilst applying pressure, turn the hand wheel 90 - 100 degrees. It is important to only apply sufficient pressure to cut the fabric, beacause if too much pressure is applied it will lead to the cutting mat being damaged. Lift the cutter and the specimen will remove cleanly, and with smooth edges, from the original fabric 2.2 Maintenance Instructions. The instrument requires no special maintenance, but the following is advised: • Protect the surface from dust and dirt. • Protect the edges of blades and surface of the internal pressure

plate. • After the cutting procedure it is recommended to lift the pressure

plate and blades holder in the upper position. 2.3 Replacing the Blades - M235 AB, 236A, 236C, 236E The blades (F) can be replaced by those supplied, further supplies can be obtained from SDL (SDL 236F). Please note: when ordering replacement blades, quote the model number, located on the front of this manual, as the specification for each model's blades are different.

Section 1 Introduction

1.1 Scope The M008E Digital Elmendorf is a ballistic type tearing tester which is used to determine the resistance of a material to tearing. The Elmendorf conforms to the standards and test methods below: BS EN ISO 13937 –1 ISO 9290 BS EN ISO 4674 –2 DIN 53862 ASTM D 1424 BS EN ISO 21974 ASTM D 689b-96A SCAN P 11-96 TAPPI T414 NEXT METHOD 17

1.2 Principle If the swinging pendulum is released without a sample, the pendulum will start and finish at the same height. If a sample is held in the jaws, the pendulum will swing to a lower height due to the energy absorbed by the specimen. A calculation is performed within the software, giving the tearing resistance of the sample being tested.

1.3 Description The unit comes complete with software giving a direct reading in a choice of 7 different units, no calculations are necessary. The unit features easy to change pendulum weights with the selected weight being shown on screen. The unit also incorporates safety features including a two handed pendulum release requirement. The unit features easy release clamps which tightly hold the specimen in place whilst being quick and simple to use.

STOCKPORT ENGLAND SK1 3JW

PHONE :0161 480 8485

FAX : 0161 4808580 E-MAIL : [email protected]

2.2 Installation. The unit should be placed on a sturdy bench. When deciding on a location for the unit, bear in mind that the Elmendorf incorporates a swinging pendulum. Where possible the unit should be placed in an area of low traffic to minimise the risk of danger to personnel. It is recommended that the unit is bolted to the desk using the screw holes provided. This is especially true when the two heavier weights C, and D are being used.

9

2.3 Preparation for use • The unit should be made level front to back and side to side

using the levelling screws on the base of the unit. The levelling screws should be used in conjunction with the spirit levels.

• The zeroing procedure should be carried out as detailed below:

1. Switch the power off on the unit. 2. Load the “B” pendulum onto the unit and secure the black knob. 3. Switch the power on at the back of the unit while holding the “enter”

button in at the same time. 4. Put the pendulum into the position ready to start a test. 5. Press the two release buttons and release the pendulum. 6. The unit will now swing 40 times and a message will be shown on the

screen to show that it has passed this zeroing procedure. If a fail message is shown, repeat the procedure. If a fail message is shown again contact the TECNET DEPARTMENT at the address at the beginning of this manual.

7. This procedure should be carried out at regular intervals or whenever wrong result is suspected.

2.4 Safety Instructions • Read this manual thoroughly before using the unit. • Take care when handling the blade. • When the instrument is not in use, the pendulum should be in the

released mode. • Ensure the pendulum is disarmed before the unit is powered up. • When operating the instrument make sure to keep the head out

of the arc in which the pendulum swings. • Ensure that the weights are securely mounted on the unit before

releasing the pendulum. • Do not store spare pendulum weights on the instrument base.

10

Section 3 Test Procedure

3.1 Mounting the pendulum The appropriate pendulum should be mounted on the arm by unscrewing the black knob, mounting the weights and replacing the black knob again. The knob should be screwed as tightly as possible to avoid the weights rotating or becoming loose. Note: that if several tests are being carried out using the same pendulum, the black knob should be checked at regular intervals to ensure that it has not worked loose.

3.2 Specimen preparation The sample should be conditioned as required in the appropriate standard and the samples then cut using the template provided. It is essential that the samples are cut accurately as this will affect the tearing length and hence the result. The size of the specimen will depend on the standard being tested to. The knife which is used to give the initial cut should be set so that the final tearing length is 43 mm. This is usually achieved by having a specimen width of 63mm and a tear of 20mm. Alternatively the specimen width is 58 mm using a cut of 15mm for Marks and Spencer testing.

3.2 Use of the knife Take care when handling the blade. The knife is operated by pulling the handle on the left hand side of the machine towards the operator. This will pull the knife though the mounted specimen and create the cut. It is important that the knife is replaced if blunt. To change the length of cut, with the pendulum arm disarmed, slacken the screws which secure the knife. Move the blade up to increase the length of the cut and down to reduce the length of the cut. Tighten the screws and check the length of cut by cutting a piece of paper and measuring the length of cut with a steel ruler. Adjust the blade position until the correct length of cut has been achieved.

11

3.4 Use of the Software

• When the machine is initially powered up, the following message will be shown on the screen:

• Press enter, the following message will then be shown on the screen:

Section 4 Calibration and Maintenance

4.1 Calibration The unit should be calibrated by a TECNET engineer every 12 months. The digital Elmendorf is supplied with 4 checkweights, one for use with each pendulum. These are used to confirm the correct functioning of the unit. This method of checking should be used on a regular basis but does not replace an annual visit by an SDL engineer.

• Check that the unit is level, using the spirit levels attached. • With the “A” pendulum in place and the “A” check weight screwed into

the small hole drilled in the arm of the pendulum, select “A” in the software. When the screen is shown asking if the “service mode is to be chosen, select “NO” by using the arrow key. (Note: “YES” should only be selected here by SDL engineers during a calibration visit)

• Release the pendulum and record the result. The table in appendix A of this manual may be used for this.

• Repeat the test 5 times and calculate the mean. • Repeat the test using the B, C and D pendulums and checkweights.

The mean result should fall between the two sets of figures in the table below: Pendulum Min. value (N) Nominal value (N) Max. value (N)

A 3.79 3.89 3.98 B 7.69 7.86 8.03 C 15.76 16.11 16.46 D 31.70 32.41 33.11 If the reading falls outside of the range check that the unit is level and if not contact the TECNET department at the address given at the beginning of this manual.

Zeroing procedure

1. Switch the power off on the unit. 2. Load the “B” pendulum onto the unit and secure the black knob. 3. Switch the power on at the back of the unit while holding the “enter”

button in at the same time. 4. Put the pendulum into the position ready to start a test. 5. Press the two release buttons and release the pendulum.

15

6. The unit will now swing 35 times and as long as the pendulum swings 35 times within the useable range of the B pendulum, a message will be shown on the screen to show that it has passed this zeroing procedure. If a fail message is shown, repeat the procedure. If a fail message is shown again contact the TECNET DEPARTMENT at the address at the beginning of this manual.

7. This procedure should be carried out at regular intervals or whenever wrong result is suspected.

4.2 Maintenance The unit requires very little maintenance.

• Ensure that the equipment is kept clean and free from dust, especially the jaws where fluff and lint can accumulate.

• Ensure that the knife is kept sharp, replacements can be ordered from SDL ATLAS.

1.1 Description of the apparatus The M231 Perspirometer is supplied as a stainless steel frame capable of holding up to 20 samples. The samples are generally 10cm x 4cm and are held between acrylic separator plates. The unit is supplied with a weight and a supplementary plate allowing both ISO and AATCC test methods to be performed.

1.2 Standards The M231 conforms to the minimum requirements of the following standards: BS1006 BS EN ISO 20105 ISO 105 AATCC 15, 106, 107, IWSTM 6, 174, 175.

1.3 Principles To test colour fastness to perspiration, specimens (fabric, yarn or fibre) in contact with multifibre fabric are treated in two different solutions. One solution is acid and one solution is alkaline. The specimens are subsequently drained and placed under a specific load between the separator plates. The units are placed in an oven for a pre determined length of time, after which time the units are removed from the oven. The specimens are removed from the separator plates and placed in an oven/incubator to dry after which they are assessed with grey scales. Note for testing colour fastness to warm water, the same apparatus is used and the solutions are substituted for distilled water.

SECTION 2 TEST PROCEDURE For the purposes of this manual the test method is according to ISO 105 . For other methods refer to the relevant standard or method.

2.1 Preparation of test solutions Solutions should be made up immediately prior to use as the chemicals can degrade over time.

Alkaline solution (makes 1 Litre) 0.5 g of l-histidine monohydrochloride monohydrate

(C6H9O2N3.HCl.H2O)

5 g of sodium chloride (Na Cl) either 5g of disodium hydrogenorthophosphate dodecahydrate (Na2 HPO4.12H2o) or 2.5 g of disodium hydrogen orthophosphate dihydrate

(Na2HPO4.2H2O)

The solution is brought to pH 8.0 with 0.1 mol sodium hydroxide solution.

Acid solution (makes 1 Litre)

0.5 g of l-histidine monohydrochloride monohydrate (C6H9O2N3.HCl.H2O)

5 g of sodium chloride

(Na Cl)

2.2 g of sodium dihydrogen orthophosphate dihydrate (NaH2PO4.2H2O)

The solution is brought to pH 5.5 with 0.1 mol sodium hydroxide solution.

6

2.2 Preparation of test specimens. If the textile to be used is fabric either:

Attach a specimen measuring 40mm x 100mm to a piece of the multifibre adjacent fabric also measuring 40mm x 100mm, by sewing along one of the shorter sides with the multifibre next to the face of the fabric

OR

Attach a specimen measuring 40mm x 100mm between the two single fibre adjacent fabrics, also measuring 40mm x 10mm, by sewing along one of the shorter sides.

If the textile to be tested is yarn or loose fibre, take a mass of the yarn or loose fibre equal to approx. one half of the combined mass of the adjacent fabrics and either:

Place it between 40mm x 100mm piece of the multifibre fabric and a 40mm x 1oomm piece of non dye-able fabric and sew them along 4 sides.

OR Place it between a 4omm x 10mm piece of each of the two

specified single fibre fabrics and sew along all 4 sides.

2.3 Procedure

Lay out the composite specimen smooth in a flat bottomed dish and cover with the solution. Thoroughly wet one composite specimen in the alkaline solution at a liquor ratio of 50:1 and allow it to remain in the solution for 30 minutes. Press and move it from time to time to ensure good and uniform penetration of the liquor. After this time interval pour off the solutions and wipe the excess liquor off the specimen by using two glass rods. Place the composite specimen between two of the acrylic plates which are placed on the frame of the perspirometer (referring to figures 1 and 2). Remember to use one frame for acid solutions and one frame for alkali solutions. Repeat this procedure for all specimens required.

7

After application of the loading weight(s), tighten the nuts on the top clamping plate and remove both the loading block and the extra weight (if used). Pour off any excess liquor. Place each perspirometer containing the specimens in an oven for 4 hours at 37°C ± 2°C. Open out each specimen by breaking the stitching on one of the shorter sides. Dry the specimen in the air at a temperature not exceeding 60°C with the two or three parts in contact only at the line of stitching.

4 Assessment Assess the change in shade of the sample and the staining of the adjacent fabrics with the grey scales.

2.5 Test report The test report should contain the following information:

The number and the date of the standard being tested to. Sample identifiers. The numerical ratings for the staining and the change in shade. Which adjacent fabrics or mutifibre strip was used.

The unit is free standing and should be located close to the services required:

• A drain for excess water • A cold water supply • Power supply (see table on page 3 for details)

It is recommended that the unit be placed in an area of low traffic since the lid of the unit can become hot during use and steam will be produced which will escape through the vents in the lid. Please leave a distance of at least 3 inches (8cm) free on the right hand side of the machine to allow the cooling fan to function properly and to allow access to the isolator switch The unit is intended to be permanently plumbed in to a cold water supply and to drain. A manual drain is also built into the unit in case this should be needed. This is located underneath the tank. The tank is automatically filled and drained by valves. SDLATLAS recommend that the unit be connected to the electricity supply by a qualified electrician.

Section 3 Test Procedure Safety Notes:

• When testing at elevated temperatures, the lid of the bath will become hot. Do not place items on top of the lid or touch the lid during use. A sticker which turns red at elevated temperatures is in place on the lid.

• When testing at elevated temperatures, take care as steam will escape from

the lid as it is opened.

• Use heat protective gloves when loading and unloading pots.

• If the unit is to be left unused for any length of time, it is recommended that the water be drained out of the unit.

• The emergency stop is positioned on the front of the control, this will cut

off power to the machine. 3.1 TESTING PROCEDURES For the purposes of this manual, reference is made to ISO test procedures. For specific test procedures relating to other methods, consult the relevant method. If you require specific information from standards, these standards can be purchased from SDLATLAS, please consult the sales team for availability and prices.

3.1 TEST SPECIMEN

3.1.1 If the textile to be tested is fabric either

a) attach a specimen measuring 40 mm x 100 mm to a piece of the

multifibre adjacent fabric, also measuring 40 mm x 100 mm, by sewing along one of the shorter side, with the multifibre fabric next to the face of the specimen

or b) attach a specimen measuring 40 mm x 100 mm between the two

single-fibre adjacent fabrics, also measuring 40 mm x 100 mm, by sewing along one of the shorter sides.

3.1.2 Where yarn or loose fibre is to be tested Take a mass of the yarn or loose fibre approximately equal to one-half

of the combined mass of the adjacent fabrics and either

a) place it between a 40 mm x 100 mm piece of the multifibre adjacent

fabric and a 40 mm x 100 mm piece of the non-dyeable fabric and sew them along all four sides

SECTION 1 INTRODUCTION 1.1 Crease Recovery Textiles used in clothing need to have the ability of creasing and folding to conform to body shapes, giving better comfort in wear. However, to retain their appearance, they must be able to shed the creases that occur in wear and laundering. When a fibre bends, cross-links may break and rejoin in new positions, restricting recovery; or they will merely stretch and recover when the load is removed. The resistance to these creases, and the ability of the fabric to recover from creasing, is known as Crease Resistance. This can be measured qualitatively in terms of the Crease Recovery Angle. 1.2 The Shirley Crease Recovery Tester The Shirley Crease Recovery Tester is used for determining the angle of recovery of fabrics from creasing in a specified atmosphere. The Shirley Crease Recovery Tester complies with the following standards: • BS EN 22313:1992 - The Determination of the Recovery from

Creasing of a Horizontally Folded Specimen by measuring the Angle of Recovery,

• Marks and Spencer method of test - M&S P22. 1.3 Principles of the Crease Recovery Test A conditioned rectangular specimen of specified dimensions is folded and maintained folded for a measured time under a specified load, using the loading device supplied. This creasing load is then removed and the specimen allowed to recover for a specified duration in the Crease Recovery Tester.

M 003A Page 3

The Crease Recovery Angle can then be easily read from the scale of the tester.

M 003A Page 4

SECTION 2 APPARATUS AND ASSEMBLY

2.1 Assembly The M003A model of the Shirley Crease Recovery Tester and Loading Device is a dual range instrument that allows for a 2 kg test or a 1.019 kg test, as specified by varying standards. 2.2 The Shirley Loading Device The Shirley Loading Device consists of two weights sat one on top of the other, on top of a base. Each weight has a slot in it, which holds that weight steady on the base via the pole protruding from the base. The two weights have a combined load of 2 kg. To convert the loading device from a 2 kg load to a 1.019 kg load, simply remove the top weight. To convert back to a 2 kg load replace the removed weight. 2.3 The Shirley Crease Recovery Tester M003A For a 2 kg load the required sample size is 50mm x 25mm. For a 1.019 kg load the required sample size is 40mm x 15mm. To accommodate these sample sizes the instrument must be adjusted in the following way -

PLEASE REFER TO FIGURE 3 1. SAMPLE SIZE 50mm x 25mm Loosen screw (B) and push the backstop (A) as far as it will go towards the rear of the clamp. Re-tighten screw (B) and push the moveable cursor (C) downwards until stopped by the cursor peg.

M 003A Page 5

2. SAMPLE SIZE 40 mm x 15mm Loosen screw (B) and push the backstop plate (A) as far as it will go towards the front of the clamp. Re-tighten screw (B) and push the moveable cursor (C) upwards until stopped by the cursor peg. Before commencing testing, level the instrument on the surface to be used, using the levelling screws and the built in spirit level.

M 003A Page 6

SECTION 3 TEST PROCEDURE FOR BS EN 22313:1992

3.1 Apparatus Required • Shirley Crease Recovery Tester. • Shirley Loading Device - to apply a load of 10 Newtons (1.019

kg). • A Stop Watch • Tweezers with broad spade shaped jaws (as supplied with the

Shirley Crease Recovery Tester) • Paper or Metal Foil - of thickness no greater than 0.02mm. 3.2 Preparation of Specimens Rectangular specimens should be cut to dimensions of 40mm x 15mm, using the template provided. In order to ensure a representative average for the fabric tested, specimens are to be taken not less than 50mm from the selvedges and in the manner as shown in figure 3. Unless otherwise agreed by parties interested in the test results, prepare not fewer than 20 specimens for each test. Take half of the specimens with their short sides parallel to the warp, wales, or direction marked length (for nonwoven fabric), and the other half with their short sides parallel to the weft, courses, or at right angles to the length (for nonwovens). 3.3 Conditioning of the Specimens Prior to Testing Condition the specimens for at least 24 hours in the standard atmosphere determined in BS 1051 (65 ± 2% Relative Humidity, and a temperature of 20 ± 2oC), or in the atmosphere for high

M 003A Page 7

humidity determinations (relative humidity of 90 ± 2%, and a temperature of 35 ± 2oC). Ensure that all surfaces are exposed to air at all times, for instance by placing them on a wire gauze or mesh. After conditioning, handle the specimen solely with the tweezers supplied or with rubber fingerstalls. 3.4 Procedure for Testing the Crease Recovery Angle

Conduct all testing in the atmosphere in which the specimen was conditioned, as described in section

3.3. 1. The Shirley Loading Device should be set up for a 1.019 kg load. 2. Fold the specimen end to end and hold this position with the

tweezers, remembering to fold half the specimens face to face and the other half back to back. This must be done whilst gripping no more than 5mm from the ends. If the surfaces of the specimens show any tendency to adhere, place a sheet of paper or foil, 18mm x 15mm, between the limits of the specimen (see figure 4).

3. Load the specimen onto the lower plate of the Shirley Loading

Device and apply the load gently, without delay. 4. Load the specimen for 5 minutes ± 5 seconds. Then quickly

and smoothly remove the load. Using the tweezers supplied, hold in the flat of the tweezers one arm of the specimen and introduce the other arm into the specimen clamp (F) of the Crease Recovery Tester as far as the back stop (A), taking care not to disturb the existing crease formation.

5. While the specimen is in the holder, adjust the instrument

continuously to keep the suspended free limb always in a vertical position, in line with the indicator (D).

6. Five minutes after the removal of the load, read the crease

recovery angle from the circular scale at the index line (E). If the

M 003A Page 8

free limb twists or curls slightly, use a vertical plane through its centre to read the crease recovery angle.

3.5 Calculation and Expression of Results Calculate the mean value, to the nearest degree, for the following :- 1. Crease across length (e.g; warp) direction - a) face to face b) back to back 2. Crease across transverse (e.g; weft) direction - a) face to face b) back to back 3.6 Test Report The test report shall state - 1. That the tests were conducted in accordance with the standard

method as detailed in section 3.4 above; 2. The simple designation of the tested cloth; 3. The conditioning atmosphere used; 4. The date of beginning of conditioning, and duration of exposure; 5. The date of the test; 6. The number of specimens evaluated; 7. Mean values calculated to the nearest degree, as detailed in

section 3.5 above; 8. Standard Deviation and confidence interval, if required.

M 003A Page 9

SECTION 4 TEST PROCEDURE FOR MARKS AND SPENCER P.L.C.

4.1 Objective To determine the crease recovery properties of unbrushed cellulosic fabrics by measuring the angle of recovery after being folded and creased under a static load. 4.2 Apparatus Required • Shirley Crease Recovery Tester. • Shirley Loading Device - to apply a total load of 2.0 kg. • A Stop Watch • Tweezers with broad spade shaped jaws (as supplied with the

Shirley Crease Recovery Tester) • Lens Paper 30mm x 30mm - of thickness no greater than

0.02mm. 4.3 Preparation of Specimens Rectangular specimens should be cut to dimensions of 50mm x 25mm, using the template provided. In order to ensure a representative average for the fabrics tested, specimens are to be taken not less than 50mm from the selvedges and in the manner as shown in figure 3. Prepare 12 specimens for each test. Take half of the specimens with their short sides parallel to the warp, wales, or direction marked length (for nonwoven fabric), and the other half with their short sides parallel to the weft, courses, or at right angles to the length (for nonwovens).

M 003A Page 10

M 003A Page 11

4.4 Conditioning of the Specimens Prior to Testing Condition the specimens for at least 16 hours in the standard atmosphere (65 ± 2% Relative Humidity, and a temperature of 20 ± 2oC). Ensure that all surfaces are exposed to air during the whole period of conditioning, for instance by placing them on a wire gauze or mesh. After conditioning, handle the specimen solely with the tweezers supplied or with rubber fingerstalls. 4.5 Procedure for Testing the Crease Recovery Angle

Conduct all testing in the atmosphere in which the specimen was conditioned, as described in section

4.4. 1. The Shirley Loading Device should be set up for a 2 kg load. 2. Set the dial of the Shirley Crease Recovery Tester to read 20o. 3. Fold the specimen end to end with a square of lens tissue

between the limits of the specimen (see figure 4) and hold this position with the tweezers, whilst gripping no more than 5mm from the ends. Fold half the specimens face to face and the other half back to back.

4. Load the specimen onto the lower plate of the Shirley Loading

Device and apply the load gently, without delay. 5. Load the specimen for 60 seconds. Then quickly and smoothly

remove the load. Using the tweezers supplied, hold in the flat of the tweezers one arm of the specimen, allowing the lens tissue to fall out, and introduce the other arm into the specimen clamp (F) of the Shirley Crease Recovery Tester as far as the back stop (A), taking care not to disturb the existing crease formation.

6. While the specimen is in the holder, adjust the instrument

continuously to keep the suspended free limb always in a vertical position, in line with the indicator (D).

M 003A Page 12

7. 60 seconds after the removal of the load read the crease

recovery angle from the circular scale at the index line (E). If the free limb twists or curls slightly, use a vertical plane through its centre to read the crease recovery angle.

4.6 Calculation and Expression of Results Calculate the mean value, to the nearest degree, for the following :- 1. Crease across length (e.g; warp) direction - a) face to face b) back to back 2. Crease across transverse (e.g; weft) direction - a) face to face b) back to back

NOTE If the individual results achieved in any one test vary by 10° or more then repeat the test using a

further three samples cut from the retained balance of the fabric.

1.0 INTRODUCTION The SDL Atlas M233G AFC 45° Flame Chamber measures the flame-spread time of textile specimens burned at a 45° angle under controlled flame-impingement conditions. Flame impingement is controlled by an automatically activated burner flame that involves the specimen for a preset period (impingement time) and then moves away from the specimen. A timer automatically starts counting when the flame impinges on the specimen and then shuts off when a trigger string (previously threaded across the upper portion of the specimen) is burned through causing a weight to fall and activate the timer off switch. The AFC meets requirements to perform 16 Code of Federal Regulations (CFR) Part 1610, ASTM D 1230 and other test standards. (See Section 7.0 for the addresses and telephone numbers of applicable standards organizations.) This manual contains operational procedures and safety precautions.

The following items are to be supplied by the user: ! Gas cylinder containing CP-grade butane (minimum 99% pure) ! Sensitive fuel control valve ! Connector for gas inlet tubing, 3.2 mm ID x 6.4 mm OD (1/8 in ID x ¼ in OD)

4.3 Setup

1. After unpacking the AFC, place the instrument on a smooth and sturdy level surface in a fume hood or near a room exhaust system. The room should have stable temperature and humidity. (See the product specifications in Section 3.0.)

Locate the AFC away from all flammable materials. Place the gas cylinder near the AFC in a safe manner.

2. Plug the power cord into the back of the instrument. Make sure the plug is securely

inserted into the instrument.

3. Before connecting the gas tubing to the gas inlet, fill the manometer with water up to a readable level (to zero on the scale). To keep air from entering the line, tilt the instrument back and use a syringe to fill the tube.

4. With the power switch in the OFF position (see Figure 1), plug the power cord into the proper electrical outlet.

5.1 Controls (continued)

Off-On-Start Switch: Set this switch to ON to turn on power. Press the switch to the Start position to initiate a test and the impingement head will swing onto the specimen, dwell for the impingement period, and then retract to its original position. The timer starts just after the impingement head moves onto the specimen.

Impingement Controls: These four pushbuttons allow selection of the flame impingement

period. For Auto-Impinge select 1, 5 or 20 seconds. For manual control of the impingement period, select Dwell Man and then press and hold the Manual Impingement button to cause the flame to impinge on the specimen for as long as the button is pressed.

Specimen Rack Adjuster: Move this bar left or right to slide the specimen mounting rack left

or right inside the chamber. After a specimen is loaded, this bar is moved to the right so that the specimen surface contacts the Specimen Test Position Arm (Figure 1).

Timer: This timer automatically initiates counting at the beginning of the

impingement period. It stops counting when the specimen material burns to a trigger string spanning the specimen (Figure 3). The trigger string breaks and releases a small weight that activates a micro-switch, stopping the timer.

5.1 Controls (continued)

Timer Stop String Threading: Remove the hardware from the spool post. Place the flat washer on the rod, then the spool of 50 cotton mercerized thread and then the tensioning hardware and nut. Adjust the nut position just loose enough so that thread may be pulled from the spool without breaking. Follow the steps below to thread the timer string.

1. Install the specimen in the specimen holder as specified in the applicable test method.

2. Place the specimen holder on the mounting rack as shown. Adjust the rack position all the way to the right (loading position) with the adjustment bar.

3. Thread the stop string as shown and tie it to the eyelet on the stop weight while the weight is sitting in the stop switch housing.

5.1 Controls (continued) 4. Take out any slack in the string by rotating the spool.

5. Adjust the position of the specimen mounting rack to the left until the surface of the specimen contacts the Specimen Test Position Arm (Figure 1).

6. The stop weight should lift out of the switch housing and you should hear the microswitch click open. If this is not the case, rotate the spool until the stop weight lifts sufficiently to achieve this. Failure to do so will prevent the timer from starting.

5.2 Specimen Mounting Condition and mount the specimens as specified in the applicable test method. 5.3 Flame Adjustment

The impingement flame burns horizontally at the tip of a stainless steel hypodermic needle. Flame length is controlled by the pressure of the gas supply to the instrument. Open the viewing window of the AFC. Turn on the gas supply and adjust your input pressure regulator until a slight backpressure reading is indicated on the manometer tube. Light the burner. Allow a minute for the gas pressure and the flame length to stabilize. Use the steel scale to measure the flame length which should be 16 mm (5/8 in). Make small adjustments in the gas pressure setting until the flame is the proper length. Be sure to allow at least 60 seconds between gas adjustments for the flame to stabilize and the manometer liquid to settle.

NOTE! If the gas is adjusted roughly, water may be ejected from the manometer. Be sure to replace any water to maintain the correct initial water level.

5.4 Timer Prior to running a test, press the reset button on the face of the timer to reset it to zero. The timer activates at the beginning of the flame impingement period (when the flame contacts the specimen) and stops when the stop string burns through releasing the timer stop weight into the switch well.

Rev. 3.0 Doc. P/N 18306400 8


5.0 OPERATION (continued)

5.5 General Operating Scheme The operator inserts the fabric specimen into a holder and places it on the mounting rack in the test chamber. The operator threads a timer stop string above the specimen and attaches it to a weight suspended above the timer stop switch. The specimen rack is then moved into the test position (left) until the specimen contacts the test position arm. The operator turns on the gas, lights the impingement head gas jet, and adjusts the flame. After closing the chamber door, the operator selects the auto-impingement time, and presses the Start button. The impingement head swings down into the ignition position (onto the specimen) and the timer starts. After the auto-impingement time is reached, the impingement head automatically swings back from the specimen. If the sample ignites and burns through the timer stop string, the stop weight drops and shuts off the timer. The flame-spread time, which is the interval from impingement to shut-off, is recorded (as indicated on the timer) and the specimen is evaluated for burn characteristics as specified in the applicable test method.

5.6 Brushing Device (Optional) An optional Brushing Device (Figure 4) is used for preparing fabrics having a raised-fiber surface. It consists of a base with a moveable carriage and hinged nylon bristle brush.

1. Clamp the specimen in its holder onto the moveable carriage. 2. Raise the brush and push the carriage to the rear of the device. 3. Lower the brush to the face of the specimen and draw the carriage forward by hand at a

uniform rate as specified in the applicable test method.

6.0 MAINTENANCE Test Chamber Clean the test chamber at the end of each day of testing. Remove burnt debris and wipe down the walls and floor with a non-flammable solvent to prevent the accumulation of odorous or toxic residues. Clean the test chamber window as necessary for viewing. Clean the glass with a suitable window glass cleaner. Specimen Holders Regularly clean all specimen holders with a suitable solvent or detergent. Burner Before every test, inspect the burner needle and confirm it is not bent, loose or damaged. Replace as necessary according to the instructions below.

Rev. 3.0 Doc. P/N 18306400 10


6.0 MAINTENANCE (continued)

Burner Needle Replacement The burner needle must be replaced if it is damaged or will not produce an even flame. A burner needle positioning template, (Part No. 18370600) shown in Figure 5, is provided with the AFC to facilitate correct needle installation. An indicator screw protruding from the template defines the location the burner hypodermic needle tip should be in when the burner is in the impingement position. 1. Unplug the AFC power cord.

2. Remove the chamber window from the AFC enclosure by sliding it up and out of the side tracks.

3. Carefully unscrew the burner needle from the copper burner tube.

4. Apply a small amount of sealant (GE RTV 159 high-temperature sealant or equivalent) to the threads on the burner tube.

5. Screw and secure the new burner needle onto the copper tube.

6. Place the needle positioning template into the specimen mounting rack as shown in Figure 5.

7. Adjust the rack position so that the needle positioning template arm is contacting the test position arm.

8. Manually swing the burner toward the specimen until it stops.

9. Adjust the burner hypodermic needle position so that the needle tip is as close to the template indicator screw as possible, but not in contact with it, by carefully bending the copper burner tube slightly.

10. Allow the burner tube to retract to its normal position and then manually swing it towards the specimen again to recheck the needle position. Adjust as necessary.

Rev. 4.0 Doc. P/N 14112200 4

AATCC Crockmeter™

5.0 CM-1 OPERATION The CM-1 is the hand-operated AATCC Crockmeter and is ideal for short-run tests. It has a resettable 0 to 999-stroke counter that counts the number of times the meter handle is cranked. Before performing a test, the operator covers the instru-ment’s base with abrasive paper to keep the test specimen from sliding. The specimen is then clamped atop the paper to the base with the specimen holder. Test cloth is fastened to the rubbing finger with a spring clip. Beginning with the finger resting on the specimen at the base’s front end, the operator cranks the meter handle for the specified number of strokes. The finger, which rests on the specimen with a force of 9 newtons, traverses a pre-set path of 104 +/- 3 mm (4 in). The stroke length can be adjusted to 50 or 76 mm (2 or 3 in) de-pending on the specimen’s size. The test cloth is removed after the specified number of strokes and the circular image is evaluated according to the test method. 5.1 Mounting the Specimen and Test Cloth

1. Attach the rubbing arm to the hook on the drive arm above so that the finger no longer rests on the base of the instrument.

2. Center a piece of abrasive paper, abrasive side up, on the base of the Crockmeter. The paper’s long dimension should be in the direction of the rubbing. With the paper’s short edge meeting the base’s front edge, tape the paper’s long sides to the base.

3. Place the specimen flat and face-up on the abrasive paper. The specimen’s long dimension should be in the direction of the rubbing with the finger centered and resting on test area.

4. To secure the specimen, center the specimen holder over the instrument’s base with the holder’s enclosed end flush with the base’s front edge. Push the holder down firmly over the base until it lies directly on the specimen.

5. Center a piece of test cloth over the finger so that the weave is parallel with the direction of rubbing. Wrap the sides of the cloth evenly around the finger, making sure the cloth is smooth and taut over the finger’s rubbing area.

6. With the spring clip’s loops facing upward, secure the cloth by squeezing the loops together and pushing the spring clip onto the finger. Lower the covered finger onto the test specimen.

To keep from damaging the finger or arm, do not allow the arm to drop onto the instrument’s base.

AATCC Crockmeter™

5.2 Adjusting the Stroke Length The path, or stroke length, traversed by the rubbing finger may be adjusted to 50, 76 or 104 mm (2, 3, or 4 in) to accommodate the specimen’s size. To adjust the stroke length, use a flat screwdriv-er to loosen the screw securing the drive arm to the crank arm. Note the orientation of the washer for the proper spacing between the arms. Move the drive arm to the desired setting and tighten the screw. (See the CM-5 crank/drive arm detail in Figure 2, which is the same for the CM-1.) 5.3 Resetting the Cycle Counter The cycle counter is located on the shaft between the crank handle and drive arm. To reset the counter, turn the knob until the counter reads “000.” 5.4 Testing a Specimen

1. Make sure your specimen and test cloth are properly mounted (see Section 5.1 above).

2. Reset the cycle counter.

3. Position the finger on the specimen at the base’s front end and turn the handle at the rate of one turn per second for the number of strokes specified by the test method. (Each back and forth motion of the arm equals one stroke. For accuracy, note the change on the stroke counter.)

4. When the desired number of strokes is reached, remove the specimen and evaluate it ac-cording to the test criteria.

Rev. 4.0 Doc. P/N 14112200 6

AATCC Crockmeter™

6.0 CM-5 OPERATION The CM-5 is the motorized AATCC Crockmeter and is rec-ommended for frequent use and long-run tests. This model provides a uniform stroke rate of 60 revolutions per minute, automatic shut-off, a digital cycle counter, and a removable stroke arm safety cover. Before performing a test, the operator covers the instru-ment’s base beneath the finger with abrasive paper to keep the specimen from sliding. A test specimen is then clamped atop the paper to the base with the specimen holder. Test cloth is fastened to the rubbing finger with a spring clip. The CM-5 uses a digital cycle counter that automatically counts up to the specified number of strokes and stops, sounding a buzzer. The finger, which rests on the specimen with a force of 9 newtons, traverses a pre-set path of 104 +/- 3 mm (4 in). The stroke length can be adjusted to 50 or 76 mm (2 or 3 in) depending on the specimen’s size. The test cloth is removed after the specified number of strokes and the circular image is evaluated according to the test method. 6.2 Operational Precautions 6.2.1 Emergency Power Disconnect In an emergency, unplugging the cord from the CM-5’s back panel socket will disconnect all power to the instrument. The CM-5 will immediately shut down and the test will stop. To resume operation, turn the power switch in front of the instrument to OFF, connect the cord, and turn the power switch to ON. 6.2.2 Stopping a Test in an Emergency Turn off the circuit breaker ON/OFF switch beside the cycle counter and the CM-5 will shut off com-pletely. The counter will display the counted value; Turn on the circuit breaker ON/OFF switch and push the start button, the test can be continued & the counter is continued count up.

Doc. P/N 14112200 Rev. 4.0 7

AATCC Crockmeter™

6.2.3 Fuse Replacement The CM-5’s cycle counter is protected against overload by a glass cartridge fuse. The fuse is easily accessible on the instrument’s central panel on the back of the CM-5 where the power cord enters the housing. Replace it only with a 0.25 A/250 V, slow blow fuse

If the fuse blows or is removed, all instrument components power will be shut off and the arm will stop.

Never operate the CM-5 without the protective base cover installed over the linear reciprocating arm. Never touch the moving parts of the CM-5 while it is operating. Use caution when working with liquids and electricity because of a potential electrical shock hazard.

6.3 Mounting the Specimen and Test Cloth

1. Hold the rubbing arm up so that the finger no longer rests on the base of the instrument and move the hold-up pin to the right to support the rubbing arm.

2. Center a piece of abrasive paper, abrasive side up, on the base of the Crockmeter. The pa-per’s long dimension should be in the direction of the rubbing. With the paper’s short edge meeting the base’s front edge, tape the paper’s long sides to the base.

3. Place the specimen flat on the abrasive paper, image side up. The specimen’s long dimen-sion should be in the direction of the rubbing with the finger centered and resting on test area.

4. To secure the specimen, center the specimen holder over the instrument’s base with the holder’s enclosed end flush with the base’s front edge. Push the holder down firmly over the base until it lies directly on the specimen.

5. Center a piece of test cloth over the finger so that the weave is parallel with the direction of rubbing. Wrap the sides of the cloth evenly around the finger, making sure the cloth is smooth and taut over the finger’s rubbing area.

6. With the spring clip’s loops facing upward, secure the cloth by squeezing the loops together and pushing the spring clip onto the finger. While holding the rubbing arm up, move the hold-up pin to the left to release the arm for operation. Lower the covered finger onto the test spe-cimen.

7.0 CM-6 OPERATION The manually operated CM-6 has a reciprocating rotary finger and is used for tests with prints on small colored areas. When the standard weight is used, the 16-mm diameter finger rests on the specimen with a force of 11.1 newtons. The finger rotates 1.125 turns clockwise, then counterclockwise as the operator turns the handle in one direction. The pressure in conjunction with abra-sive paper on the base of the instrument holds the spe-cimen immobile while being tested. The head of the in-strument tilts away from the base for easy loading and unloading of specimens. 7.1 Mounting the Specimen and Test Cloth

1. Remove the test weight from the vertical rod.

2. Tilt the upper half of the instrument away from you to access the base. Center a piece of ab-rasive paper, abrasive side up, on the base of the instrument beneath the finger. Tape the paper’s short sides to the base.

3. Center a piece of test cloth over the finger and wrap the sides of the cloth evenly around the finger. Make sure the cloth is smooth and taut over the finger’s rubbing area. With the spring clip’s loops facing upward, secure the cloth by squeezing the loops together and pushing the spring clip onto the finger.

4. Hold a test specimen on the abrasive paper at the point where the finger meets the base. Tilt the upper half of the instrument back to the original position so that the test cloth is in contact with the test specimen.

5. Place the test weight on the vertical rod to apply pressure to the finger.

7.2 Testing a Specimen

1. Holding the test specimen in place with one hand, turn the hand crank at the rate of one revolution per second for the number of turns specified by the test. (One turn of the crank produces two reciprocal turns of the finger.)

2. When the desired number of strokes is reached, remove the specimen and evaluate it ac-cording to the test criteria.

8.0 CM-1 AND CM-5 OPTIONS SDL Atlas offers a full line of interchangeable crocking fingers and arms to comply with a variety of industry and organizational test specifications. The most commonly used fingers and arms are listed below. For these and other AATCC Crockmeter accessories and replacement parts, contact SDL Atlas Customer Service.

8.1 Replacing the Finger 1. Remove the screw located above the finger on the side of the rubbing arm. 2. Pull the finger straight down out of the hole in the underside of the arm. 3. Insert the replacement finger into the hole and tighten the screw. If the finger has a flattened

edge, the flat side should face the screw.

8.2 Acrylic Fingers The standard rubbing finger for the CM-1 and CM-5 is a 16-mm (0.63-in) diameter acrylic rod. A larger acrylic finger is available to provide a 25 mm (1 in) rubbing surface.

8.3 Wet Test Finger An optional hollow nylon finger is available for wet and solvent crocking tests. The nylon finger has the same dimensions as the standard finger but offers increased chemical resistance. It has a side-loading hole for applying measured amounts of liquid to be evenly bled into the test cloth by four feeder holes. When filled with a solvent such as MEK (methyl ethyl ketone), for example, it can be used to evaluate the degree of curing and sensitivity to abrasion of ultraviolet-cured printing inks. The fingers are secured with a screw on the side of the arm.

To make sure that the finger is properly seated in the arm, run a test using the Crockmeter calibration cloth and check that the image pro-duced is even.

8.4 Crock Block The crock block provides a rectangular rubbing surface of 19 x 25.4 mm (0.75 x 1 in) and is used for testing textile floor coverings. It is attached to the drive arm by a screw on the side of the arm. The screw can be replaced by a 10-32 x 20 mm Allen-socket cap screw that can be tightened or loosened by hand. A rectangular slip-on sleeve is provided with the crock block to enable the operator to mount test cloth while the block is still attached to the drive arm.

8.5 Yarn Testing Finger For testing yarns and threads, an optional acrylic test finger is available. The finger is 25 mm (1 in) in diameter and 51 mm (2 in) long. Positioned on its side and held in place by the standard fin-ger, it provides a wider test area and rounded surfaces to eliminate digging. The standard test cloth is used and is fastened by two spring clips that are provided with the finger.

8.6 Lighter-Weight Arms The standard arm for the CM-1 and CM-5 rests on the specimen with a force of 9 newtons. For tests that specify a lighter force, SDL Atlas offers a mid-weight (3 newtons) and lightweight arm. (These arms lack the clip for the CM-1’s suspension hook to accommodate holes that lighten the weight.) To change the arm, remove the screw securing the drive arm to the crank arm (note the orientation of the washer) and remove the rubbing arm assembly from the instrument. Insert the new rubbing arm assembly into the guide track. Attach the drive and lever arms by inserting the washer and screw in the desired stroke-length setting then tighten the screw.

9.0 MAINTENANCE All AATCC Crockmeter models are virtually maintenance free. No lubrication is necessary for the CM-5 and CM-6. To ensure long bearing life of the connecting shaft between the drive handle and the drive linkage in the CM-1, apply 2 or 3 drops of 10W motor oil to the oiler hole once a month. The 2.29 mm (0.09 in) oiler hole is located where the drive handle is mounted onto the connecting shaft as shown in Figure 1. Be sure to keep the rubbing block, located at the end of the drive arm above the rubbing finger in the CM-1 and CM-5, clean and free of any abrasive dirt or contamination. Keep the CM-5’s sensor free of dust by wiping it with a soft cloth as needed (see Figure 2). In general, keep the Crockmeter clean and free from oil and dirt, which may damage small compo-nents over time. Replace worn parts as necessary.

ELECTRONIC YARN TENSION METER

YARN TENSIONMETERS

Wherever during processing, yarns and threads are subject to

load, they should be checked by means of the yarn tensionmeter.

This control should take place during spinning and winding,

followed by a check during warping, especially if High Speed Warping

Equipment is used, and during weft winding.

On the latter especially, repeated checks of the yarn tension should be made.

Excessive tensions in spinning and winding results in differential dye uptake and poor

running off in warping and beaming.

The tensions obviously depend on the material and the process.

However as a good rule of thumb one can take 1/10 of the yarn weight in Deniers,

for the mean graduation on the scale.


3

Electronic Yarn Tensionmeter (Y226A)

The electronic yarn tension meter is designed for single-handed operation.

The yarn is automatically threaded and simultaneous reading of the tension

is obtained by use of the push button. Releasing the push button cuts the

power supply to save battery life. The pivoting head allows reading in any

position. The reading may be frozen for ease of assessment.

Mechanical Yarn Tensionmeter (Y226B)

The mechanical yarn tensionmeter is designed for single hand use. The thread

runs over two rollers, which, to reduce the friction, are mounted on miniature roller

bearings. Holding the instrument with the right hand, as shown on the illustration,

the inner pulley is brought into contact with the yarn to be measured, keeping the yarn

parallel to the lever on top of the instrument. The outer pulley is then pivoted to its stop

by depressing the lever. The inner pulley then takes a position which represents the

balance between the tension of the yarn and the main calibration spring in the meter.

This position, by means of a precision gear, is transmitted to the indicator hand

which shows the yarn tension on the dial of the instrument. The reading is in grams.

The maximum as well as the minimum tension should be read, the indicator hand

following the periodic variations in the tension.

The SDL Mechanical Yarn Tensionmeter is delivered complete in velvet case, its weight

including the case is 300 g (8.50 oz).

Features

• Easy to use – Single handed operation • Simple analogue gauge – Direct reading of results • Wide range available A series of models covering 0.5 - 170 gms permit assessment of tensions in most yarn processes.
