ASTM D1938-06
Historical Standard: ASTM D1938-06 Standard Test Method for Tear-Propagation Resistance (Trouser Tear) of Plastic Film and Thin Sheeting by a Single-Tear Method
SUPERSEDED (see Active link, below)
ASTM D1938
1. Scope
1.1 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.
Note 1Film has been arbitrarily defined as sheeting having nominal thickness not greater than 0.25 mm [0.010 in.].
1.2 Constant-Rate-of-Grip Separation Test This test method employs a constant rate of separation of the grips holding the test specimen.
1.2.1 Specimen extension may be measured in this test method by grip separation.
1.3 The values stated in SI units are to be regarded as standard. The values given in brackets are provided for information only.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
This standard is similar to ISO 6383-1, but is not considered technically equivalent. The specimen size for ISO 6383-1 is larger, and the method specifies different test speeds.
