ASTM-D5576 2006

1.1 This practice covers infrared procedures for determining the molecular structural features in polyolefins and polyolefin copolymers. The structural features of primary concern are the types and numbers of branches. Although this practice centers its attention on polyolefins and polyolefin copolymers, the techniques, with proper modification, can be used for some other polymers as well.

Note 1

Quantitative determinations require either an internal or an external evaluation of sample thickness. ASTM test methods available for specific features are listed in .

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 to determine the applicability of the regulatory limitations prior to use.

Note 2

There is no similar or equivalent ISO standard.
