Standard Practice for Cutting Film and Sheeting Test Specimens
SCOPE
1.1 This practice covers equipment and techniques for cutting film and sheeting specimens for testing. The specimens are nick-free, non-stretched and can be rapidly prepared.
1.2 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 similar or equivalent ISO standard.
