1.1This 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 1:Film has been arbitrarily defined as sheeting having nominal thickness not greater than 0.25 mm (0.010 in.).
1.2Constant-Rate-of-Grip Separation Test—This test method employs a constant rate of separation of the grips holding the test specimen.
1.2.1Specimen extension may be measured in this test method by grip separation.
1.3The values stated in SI units are to be regarded as standard. The values given in parentheses are provided for information only.
1.4This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Note 2: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.
1.5This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
