SECTION 2 TEST METHODS - NOTES TO TESTING LABORATORY

I. SEALANT SAMPLING The sealant to be tested should be taken directly from a randomly selected container as commercially supplied by the manufacturer. The container should be full and not previously opened. The testing should be completed within the shelf life recommended by the manufacturer. The sealant manufacturer's instructions giving any options allowed in the test methods should be obtained along with the sealant sample. II. HOW TO EVALUATE RESULTS After testing, examine each group of specimens representing a given test. Should any one specimen be found not to meet requirements, the given test shall be repeated. NOTE: Only one repeat per test. If the sealant fails the specific retest, a new sample shall be submitted and the entire specification shall be tested. III. OPTIONAL CURE, PRE-CURE OR PRE- CONDITIONING OF TEST SPECIMENS PRIOR TO EXPOSURE CONDITIONS The curing conditions for a test specimen prior to test requirement exposure; i.e., 180 ± 5oF (82 ± 3oC) for 14 days, may require moisture and/or oxygen to facilitate a cure. Also, some compounds may require a step-type temperature gradation for elimination of solvents prior to test exposure. The following conditions are examples of such options. A. 77 ± 5oF (25 ± 3oC) with 50% ± 5% Relative

Humidity.

B. 77 ± 5oF (25 ± 3oC) with 95% ± 5% Relative Humidity.

C. 100 ± 5oF (38 ± 3oC) with 95% ± 5% Relative Humidity.

D. 77 ± 5oF (25 ± 3oC) (Room Temperature Average) 45% to 65% Relative Humidity.

E. 77 ± 5o (25 ± 3oC) (45% to 65% Relative Humidity) 7 days + 7 days @ 140 ± 5oF (60 ± 3oC).

F. 77 ± 5oF (25 ± 3oC) (45% to 65% Relative Humidity) 7 days + 7 days @ 100 + 5oF (38 + 3oC).

Should any of the above variations thereof be specified by the compound manufacturer, a notation on the test report will be made indicating the conditions used. If no conditions are specified by the compound manufacturer, the standard 7 days at 77 ± 5oF (25 ± 3oC) will be used

prior to the elevated temperature exposure requirements in the test. NOTE: A maximum of 14 days and/or 158oF can be used as an optional pre-cure. IV. PEEL ADHESION PREPARATION ASTM C 794 specifies a peel strip material of desized, Grade A, Airplane Cloth, 4.28 ounces per yard, 80/84 count. One source for this material is:

R.J. Patton Company 1908 Dunlap Street Cincinnati, OH 45214

The sealant manufacturer can specify other types of strip material to insure adequate adhesion between the strip and the sealant. Other fabrics, foils, or screens may be used. The peel strip material must be described and noted on the test report. NOTE: The above company is listed for convenience only and is not, in any way, an approval or endorsement by AAMA. V. SUBSTRATE PREPARATION Unless cleaning instructions are given in the individual test method, clean all metal and glass test surfaces using the procedure outlined below. A. Always pour solvent on the rag being used. Never dip

the rag in the cleaning solvent, as this contaminates the solvent.

B. Use the "Two Rag Wipe" technique. One rag, is used to wipe off the wet solvent and contaminates from the surface. Allowing the solvent to dry on the surface without wiping with a second dry absorbent cloth merely redeposits the contaminants as the solvent dries.

C. Change to clean rags frequently as you see them becoming soiled. It is easy to see the soiling if white rags are used.

D. Always use clean containers for solvent use and storage.

E. Follow solvent supplier's recommendations for solvent use and storage.

NOTE: Sealant manufacturer and/or sealant user should test specific sealants, substrates, primers (if required) and cleaning procedures to ensure adequate adhesion is developed under actual conditions.

AAMA 800-92 Page 7

VI. GUNNABLE SEALANTS Gunnable sealants with spacer beads and mastic type tapes with spacer shims cannot be tested to some requirements within their respective specifications because spacers will not allow specified test specimen configuration or can produce results not characteristic of the same materials without spacers. Therefore, testing should be done using sealants without spacers or shims. Testing and acceptance of sealants with spacers should be agreed to between the sealant supplier and user. VII. COMPATIBILITY This specification qualifies a sealant for use. It does not address the adhesion capability of the sealant for a specific substrate nor the compatibility of the sealant with the materials it contacts. Adhesion and compatibility characteristics required for specific substrates or finishes may be determined by the following test methods: NOTE: Several alternative test methods are available from ASTM. A. TEST METHOD A - Compatibility with Plastic Glazing Beads or Setting Blocks 1. Materials Required

a. Two 600 ml high form beaker (no pouring lip). Two watch glass covers for same.

b. Air circulating oven. c. Two 4 inch (100 mm) pieces of plastic glazing bead

and/or setting block to be evaluated. 2. Procedure Apply a 1/4 inch (6.4 mm) diameter bead of bedding material to 2 linear inches (50 mm) of one 4 inch piece. Immediately place the test strip (with no compound applied) plus one 4 inch (100 mm) piece of specimen (with no compound applied) in separate beakers and cover with watch glasses. Condition for 24 hours at 77 ± 5oF (25 ± 3oC) then place beakers and strips in a 180 ± 5oF (82 ± 3oC) air circulating oven for 72 hours. After 72 hours exposure condition to 77 ± 5oF (25 ± 3oC) for a minimum of one hour. Evaluate the compatibility of the bedding compound by reporting any differences between the plastic bead or accessory with compound applied and that without compound. Observe the sealants and substrates for discoloration, staining, tackiness, softening or crazing. B. TEST METHOD B - Compatibility with Laminated Glass 1. Materials Required

a. Two 600 ml high form beakers (no pouring lip). Two watch glass covers for same.

b. Air circulating oven. c. Six pieces of laminated glass 2 inches (50 mm) x 2

inches (50 mm).

2. Procedure Apply test compound approximately 1/4 inch (6.4 mm) thick to the surface of the edge of two adjacent sides of three laminated glass pieces being sure to cover bond line (interface of glass and laminate). Immediately place three specimens with test strip (compound applied) plus three specimens (with no compound applied) in separate beakers and cover with watch glasses. Condition for 24 hours at 77 ± 5oF (25 ± 3oC) then place beakers and strips in a 180 ± 5oF (82 ± 3oC) air circulating oven for 72 hours. After 72 hours exposure, condition to 77 ± 5oF (25 ± 3oC) for a minimum of one hour. When compared to the control (Specimens without compound) there shall be no differences in fogging, separation, discoloration or cracking. VIII. RS UV LAMP ALTERNATIVE Due to the discontinuation of manufacture, the RS Sunlamp specified in these test methods may not be available for use. In the event the RS Sunlamp is not available, the following described UV source is permitted for use as an alternative. This alternative is permitted for use in place of the RS lamp as described in all AAMA 800-92 test methods and is also permitted for use in place of the RS lamps that may be called out in the ASTM test methods referenced in AAMA 800-92. A. ALTERNATE UV SOURCE 1. The UV source consists of an exposure box containing

UVA-340 florescent UV lamps positioned at a distance of 4 inches + 1/4 inch from the surface of the test specimens.

2. Conventional four-lamp florescent fixtures are acceptable with the test specimens being oriented within the confines of the reflector hood of the fixture.

NOTE: UVA-340 Lamp Rotation - after 450 to 500 hours of lamp operating time, rotate lamps as specified in ASTM G 53. 3. The exposure box should be provided with a source of

heat to maintain the test temperatures prescribed by each method. Both incandescent and infrared lamps have been used successfully but any heat source is acceptable.

4. The UVA-340 lamps are available from:

The Q-Panel Company 26200 First Street Cleveland, Ohio 44145 PH: (216) 835-8700...FAX: (216) 835-8738

2.11 TEST METHOD FOR WATER RESISTANCE 2.11.1 GUNNABLE COMPOUNDS 2.11.1.1 Materials Required 2.11.1.1.1 Three standard etched and anodized (AA M10 C22 A31) aluminum panels 3-3/8 inches (86 mm) x 6-3/4 inches (172 mm) x .032 inch (.80 mm) thick. 2.11.1.1.2 Air circulating oven. 2.11.1.1.3 One half inch (12.5 mm) wide masking tape. 2.11.1.1.4 Three glass panels 3-3/8 inches (86 mm) x 6-3/4 inches (172 mm) (single strength). 2.11.1.1.5 Three rigid plates, steel or aluminum 3-3/8 inches (86 mm) x 6-3/4 inches (172 mm) x 1/4 inch (6.4 mm) thick. 2.11.1.1.6 Three weights, 2 pounds (.91 kg) each. 2.11.1.2 Procedure Prepare three specimens as follows: Place two 1/2 inch (12.5 mm) wide strips of masking tape on the face side of the aluminum test panel surface. Position the strips parallel to each other using the panels long edges as guides. These strips run the entire length of the panel. (The tape in position on each edge of the face side is approximately .007 inch (.18 mm) thick.) Place an additional strip of 1/2 inch (12.5 mm) tape on top of each applied tape. Position this tape so that it covers the entire length of the panel. (This double thickness of tape will serve as a .014 inch (.36 mm) spacer.) Apply a 1/8 inch (3.2 mm) diameter bead of test compound approximately 1/2 inch (12.5 mm) inside and parallel to each side of the panel. Apply across bottom of the panel to complete the "U" shape trough. Holding the single strength glass by its edges, carefully place it on the sealant and gently press down until some resistance is felt. Do not attempt to force the glass to contact the tape and avoid rocking or sliding motion while pressing. Repeat on the remaining specimens. Set the assemblies on a level surface and lay a rigid plate on each. Set a 2 pound (.9 kg) weight on the plate in order to press and hold the assemblies for 24 hours at 77 ± 5oF (25 ± 3oC). At the end of 24 hours remove the weight and plate and allow the specimens to cure undisturbed for an additional 6 days at 77 ± 5oF (25 ± 3oC). Place specimens at 180 ± 5oF (82 ± 3oC) for 7 days. Cool at room

temperature and fill trough with tap water. Stand in vertical position for 14 days.

(2 Kg). 2.19.1.8 A tray which can be clamped by the stationary head and will restrain a test panel to remain perpendicular to the movable head, yet allow test panel to slide within the tray. 2.19.1.9 Reinforced pressure sensitive tape, (Fiberglass or polyester film) 1/8 inch (3 mm) to 1/4 inch (6 mm) wider than the tape being tested. 2.19.1.10 Samples of the tape to be tested. Width of tape shall be between 1/2 inch (13 mm) to 1/4 inch (6 mm) wider than the tape being tested. 2.19.2 PROCEDURE 2.19.2.1 Scrub the application surface of all metal and glass panels with a cleaning solvent. Repeat procedure with a rinsing solvent. Dry wipe each panel insuring no solvent or lint remains. Do not contaminate panel surface by stacking or by touching with fingers. 2.19.2.2 Discard the first two layers of the tape from the roll. Place the tape specimen on each panel, centered running parallel with the longer side. Specimen shall be flush on one and have an overhang of 3 inches (76 mm) to 5 inches (127 mm) on the other end of the panel. Avoid trapping any air pockets under the specimen. If the adhesive surfaces on a double coated tape differ from one side to the other, then both should be tested and reported. In these situations, when testing the second adhesive surface, adhere the face side of the total length of the specimen, with liner, to a strip of the reinforcement tape. Remove the liner and apply the specimen to the test panels as described above. 2.19.2.3 In the case of tape widths of less than one inch (25 mm), cut additional strips from the same roll and apply parallel and adjacent to the test specimens to provide a total width of one inch (25 mm) for rolling

purposes. Pass the PSTC roller, without application of additional pressure over the backing of the tape lengthwise, one in each direction at the approximate rate of 12 inches (205 mm) per minute. Once rolling is complete, remove any additional strips from the panel while not disturbing the test specimen. Carefully remove the liner from all test specimens. 2.19.2.4 Apply the reinforcement tape to each specimen on the side from which the release liner was removed. Apply the reinforcement tape starting on the end of the panel that has the specimen flush and continue across the panel. Insure that the test specimen is completely covered by the reinforcement tape. Fold the reinforcement tape over the test specimen overhang approximately 2 inches (51 mm) so the edges of the reinforcement tape adheres to itself. This is to insure that values obtained are strictly adhesion oriented and not a combination of tensile and adhesion. Insure that the reinforcement tape does not adhere to touch the panel at any time. 2.19.2.5 Condition the specimens in accordance to the following schedule: A. 3 Glass and 3 aluminum panels at 32 ± 5oF (0 ± 3oC) for 24 hours. B. 3 Glass and 3 aluminum panels at 120 ± 5oF (49 ± 3oC) for 24 hours. 2.19.2.6 Remove each panel from its conditioning environment (one at a time and place the panel in the environmental chamber for a minimum of 15 minutes of until the specified temperature is stabilized in the chamber. Insert the overhang of the specimen into the jaws of the movable head. Insure that the tray is exactly perpendicular to the pulling direction and that the movable head is located directly over the test specimen. 2.19.2.7 Test the specimen by peeling at a rate of 12 inches (304 mm) per minute. After the first inch of the specimen is removed from the panel, record the peel adhesion values over approximately the next 4 inches (102 mm) at approximately 1/2 inch (12.7 mm) intervals. Do not take any readings during the removal of the last inch of the specimen from the panel. Try to keep the angle of separation as close to 90o as possible. 2.19.2.8 Calculate the average peel value from all reading for each sample. Convert average value to pounds/inch width. Report the converted average value for each of the 12 specimens.
