ASTM D6248
1. Scope
1.1 This test method covers most types of polyethylene, those ethylene plastics consisting of ethylene and alpha-olefin comonomers longer than propylene, and blends of the above in any ration.
1.2 The values stated in SI units are to be regarded as the standard.
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. Specific hazards statements are given in Section 8.
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
