(Test Method)Standard Test Method for Puncture-Propagation Tear Resistance of Plastic Film and Thin Sheeting
Standard Test Method for Puncture-Propagation Tear Resistance of Plastic Film and Thin Sheeting
SCOPE
1.1 This test method covers the determination of the dynamic tear resistance of plastic film and thin sheeting subjected to end-use snagging-type hazards.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 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.
Note 1—There is no equivalent ISO test method.
