FOREWORD

This Indian Standard (Second Revision) was adopted by the Bureau of Indian Standards, after the draft finalizedby the Paper and Its Products Sectional Committee had been approved by the Chemical Division Council.

This standard was first published in 1966 and subsequently revised in 1977 by modifying grammages of variousgrades of paper to suit the requirements of the users and to economize on the cellulose raw materials. Dependingon the users preferences during that time Grade 1 was introduced under Type 2, Grade 2 of Type 3 was re]moved,and the requirement of porosity was included to take care of excessive pin holes in the base paper.

‘file quality of the base paper prescribed for making the following types of carbon papers is laid down in thisstandard:

A scheme for label Iing environment friendly products known as ECO-Mark has been introduced at the instance ofthe Ministry of Environment and Forest (MEF), Governrnent of India. The ECO-Mark scheme would beadrninistered by the Bureau of Indian Standards (B IS) under the BISAct, 1986 as per the Resolutions No. 71 dated2 I February 199 I and No. 425 dated 28 October 1992 published in the Gazette of the Government of India. Fora product to be eligible for marking with ECO logo, it shall also carry the 1S1Mark of BIS besides meetingadditional environment friendly requirements. For this purpose, the Standard Mark of BIS would be a single markbeing a combination of the 1S1 Mark and the ECO logo. Requirements to be satisfied for a product to qualify forthe BIS Standard Mark for ECO friendliness, will be optional; manufacturing units shall be free to opt for the1S1 Mark alone also.

This standard, therefore, incorporates environment friendly requirements for cover paper which is based on theGazette Notification No. 455 dated 13 November 1992 for paper as environment friendly products published inthe Gazette of India.

This standard contains clauses 4.4 and 5.1 which permit the purchaser to use his option for selection to suit hisrequirements.

The composition of the Committee responsible for the formulation of this standard is given in Annex B.

For the purpose of deciding whether a particular requirement of this standard is complied with, the final value,observed or calculated, expressing the result of a test or analysis shall be rounded off in accordance withIS 2: 1960 ‘Rules for rounding off numerical values (revise@’. The number of significant places retained in therounded off value should be the same as that of the specified value in this standard.

METHOD FOR DETERMINATION OF POROSITY

A-1 APPARATUS

A-l. ] Air Resistance Apparatus

The apparatus consists of an outer cylinder which ispartly filled with oil, and an inner cylinder, having anopen or closed top, sliding freely in the outer cylinder.Air pressure provided by the mass of the inner cylinderis applied to the specimen held between clampingplates in a circular orifice having an area of 6.4 cm2.The clamping plates may be at the top of the innercylinder, or may preferably be mounted on the base ofthe apparatus. An elastic gasket which is attached tothe clamping plate on the side exposed to air pressureprevents leakage of air between the surface of the paperand the clamping plate.

A-1.1.1 The gasket consists of a thin, elastic oilresistant, non-oxidizing material having a smoothsurface (see Note). The inside diameter of thegasket is 28.6 + O.1 mm and the outside diameter34.9 + 0.1 mm. The aperture in the gasket is accuratelyaligned with the aperture in the clamping plates. Toalign and protect the gasket in use, it is cemented in agroove machined in the clamping plate. The groove isconcentric with the aperture in the opposing plate. Itis 28.41 + 0.04 mm in internal diameter and0.45 + 0.05 mm deep. Its outside diameter is35.14 & 0.04 mm for convenience in inserting andattaching the gasket.

NOTE — Thiokol, grade ST, polished plate moulded,0.8 mm thick, 50 to 60 IRHD is satisfactory.

A-1.1.2 The outer cylinder is 25.4 cm high with aninternal diameter of 82.6 mm. It has four vertical bars,each 245.5 mm long, and 2.4 mm in diameter, mountedequidistantly on the inner surface of the outer cylinderto serve as guides for the inner cylinder. The innercylinder is made of aluminium or its alloy, graduatedin units of 50 ml, and has range of 350 ml. The volumetolerance is 0.5 percent. It is 25.4 cm high, and has anexternal diameter of 76.2 mm and an internal diameterof 74.1 mm. It weighs 567.0 + 0.5 g, so as to producea pressure of 12.4 cm H20.

NOTE — Some inner cylinders are also graduated in units of25 ml for the first 100ml and have an additional graduation at400 ml.

A-1.2 Timer

Stopwatch or electric timer, capable of recording timeto the nearest 0.2 s.

A-2 MATERIALS

The outer cylinder is filled with a lubricating oil having

4

a viscosity of 10 to 13 cSt at 37.8°C and a flash point.. a-,.-

Of “at least 13>UC.

NOTE — A light spindle oil is suitable for this purpose. Oil isused in preference to water because it does not affect themoisture content of the specimen nor does it corrode theahrminiuminnercylinder. The oil should not contain any easilyvolatile fraction, and for that reason, a minimum flash point isspecified.

A-3 CALIBRATION

Test the apparatus for air leakage by clamping a thinpiece of smooth impervious metal foil or cellulose filmbetween the orifice plates, using the method prescribedin A-5.2 to A-5.5. A maximum leakage of 50 ml in5 h is allowable.

A-4 TEST SPECIMENS

From each test unit of the sample prepare at least tentest specimens, each about 5 cm wide and 12.5 cmlong except that the specimens of size larger than 5cm in both directions may be used in the apparatushaving the clamp on the base.

A-5 PROCEDURE

A-5.1 Condition the test specimens in an atmospherehaving 27+ 2°C temperature and a relative humidityof 65 + 5 percent.

A-5.2 Place the instrument on a level surface so thatthe cylinders are vertical. Fill the outer cylinder withoil to a depth of about 12.5 cm as indicated by a ringmarked on the inner surface of the cylinder.

A-5.3 For the instrument having the clamp at the topof the inner cylinder, raise the inner cylinder with onehand and clamp the specimen with the other. Thenlower the inner cylinder and allow it to float in the oil.Alternatively, remove the inner cylinder, clamp thespecimen and lower the cylinder gently in the outercylinder.

NOTE — The proper procedure is to tighten the knurlednuts alternately so that the clamping pressure is equal onboth sides. Ifonly one nut at a time is tightened, the clamp willnot bear evenly on the specimen and air leakage will probablyoccur.

A-5.4 For the instrument having the clamp on thebase, raise the inner cylinder until its rim is supportedby the catch, clamp the specimen between theclamping plates and then lower the inner cylindergently until it floats.

A-5.5 As the inner cylinder moves steadily downwards,determine the number of seconds, to the nearest 0.2 s,required for the first two consecutive 50-ml intervals

to pass the rim of the outer cylinder, starting at the and five specimens with the wire side up.zero point. In cases where a steady movement of theinner cylinder is not attained before the zero mark is A-6 REPORT

reached, timing may be started at the 50 ml mark.For each test unit, report the porosity as the average

NOTE — Avoid subjecting the apparatus to vibration, as this time, in seconds required to displace 100 ml of airincreases the rate ot’air displacement.
