Indian Standard
METHODS OF TEST FOR
COATED AND TREATED FABRICS
PART 12 DETERMINATION OF TACK-TEAR
RESISTANCE

0. FOREWORD
0.1 This Indian Standard ( Part 12 ) was adopted by the Bureau of
Indian Standards on 12 June 1987, after the draft finalized by the Treated
Fabrics Sectional Committee had been approved by the Petroleum, Coal
and Related Products Division Council.
0.2 Tack-tearing resistance provides useful information about the quality
of coated fabrics, primarily vinyl plastic coated fabrics, used for furniture
or automotive applications.
0.3 This standard is essentially based on ASTM D 751-1979 Standard
methods of testing coated fabrics - Tack tear resistance’, issued by the
American Society for Testing and Materials.
0.4 In reporting the reSult of a test or analysis made in accordance with
this standard, if the final value, observed or calculated, is to be rounded
off, it shall be done in accordance with IS : 2-1960*.

1. SCOPE
1.1 This Indian Standard ( Part 12 ) prescribes the method for measure-
ment of resistance of a coated fabric to tearing under conditions simulating
an installation that has been tacked in place.
2. APPARATUS
2.1 The apparatus shall consist of the device illustrated in Fig. 1.
3. TESTING MACHINE
9.1 The machine shall consist of three main parts:
a) Straining mechanism,
b) Clamps for holding specimen, and
c) Load and elongation recording mechanism(s).

*Rules for roundingoff numerical vaIues ( raised ).

FIG. 1 TACK-TEAR TESTER FOR COATED FABRICS

 IS : 7016 ( Part 12 ) - 1987

3.1.1 Straining Mechanism - A machine, wherein the specimen is held

between the two clamps and strained by a uniform movement of the pull-
ing clamp, shall be used. Unless otherwise specified in the material
specification, the machine shall be adjusted so that the pulling clamp shall
have a uniform speed of 5 f 0.2 mm/s.
3.1.2 Load and Elongation Recording Mechanism(s) - It shall consist of
calibrated dial, scale or chart to indicate the applied load and elongation.
Unless otherwise specified for load determination, the machine shall be
adjusted or set so that the maximum load required to break the specimen
will remain indicated on the calibrated dial or scale after the test specimen
has ruptured.
3.2 Capacity - If the machine is of the pendulum type, it shall be of
such a capacity that the maximum load required to break the specimen
shall be not greater than 85 percent or less than 15 percent of the rated
capacity.
3.3 Machine Efficiency - The error of the machine shall not exceed
2 percent up to and including a 200 N force ( 50-lbf ) and 1 percent
over 200 N and 1 percent at any reading within its loading range.
4. TEST SPECIMENS
4.1 The specimens shall be 50 mm in width and 150 mm in length. Two
sets of five specimens each are required, one set for warp tack-tear strength,
having the longer dimension parallel to the filling yarns, and the other set
for filling tack-tear strength havinq the longer dimension parallel to the
warp yarn.
5. PROCEDURE
5.1 Clamp the device shown in Fig. 1 in the upper jaw of the testing
machine and adjust the machine to compensate for its weight. Impinge the
specimen on the needles, taking care that the line of needles is parallel to
the threads to be tested and exactly 12.5 mm from the top edge of the
specimen. Clamp the specimen in the lower clamp. Operate the machine
as for a tension test with the distance from the bottom of the needles to
the top of the lower clamp as 75 mm and the rate of jaw separation as
5 mm/s with no load. The faces of the bottom clamp shall measure 25 by
75 mm or more. If the machine is of the pendulum type, disengage the
pawls on the pendulum from the ratchet. Record the average force neces-
sary to tear the fabric, preferably with an autographic recording device.
6. EXPRESSION OF RESULTS
6.1 Report the median of results of five individual tests on the warp as the
warp tack-tear strength, and the median of five individual tests on filling
as the filling tack-tear strength.
