This test method covers the determination of the force necessary to propagate a tear in plastic film and thin sheeting (thickness of 1 mm (0.04 in.) or less) by a single-tear method.

The method is not applicable for film or sheeting material where brittle failures occur during testing.

Constant-Rate-of-Grip Separation Test —This test method employs a constant rate of separation of the grips holding the test specimen.

Specimen extension may be measured in this test method by grip separation.

The values stated in SI units are to be regarded as standard. The values given in parentheses are provided for information only.
