Test Methods for Methyl (Comonomer) Content in Polyethylene by Infrared Spectrophotometry

ANSI/ASTM D6645-2001 发布历史

This test method covers the determination of methyl groups (that is, comonomer content) in polyethylenes by infrared spectrophotometry. The test method is applicable to copolymers of ethylene with 1-butene, 1-hexene, or 1-octene having densities above 900 kg/m. High-pressure low-density polyethylenes (LDPE) and terpolymers are excluded. The values stated in SI units, based on IEEE/ASTM S1-10, are to be regarded as the standard. 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.

适用范围

This test method covers the determination of methyl groups (that is, comonomer content) in polyethylenes by infrared spectrophotometry. The test method is applicable to copolymers of ethylene with 1-butene, 1-hexene, or 1-octene having densities above 900 kg/m<(hoch)3>. High-pressure low-density polyethylenes (LDPE) and terpolymers are excluded. The values stated in SI units, based on IEEE/ASTM S1-10, are to be regarded as the standard. This standard does not purport to address all of the safety concerns, if any, associated with its use.
