significance And Use:
The absorption coefficient of polyolefin polymer pigmented with carbon black is useful to judge the degree and uniformity of dispersion of the pigment, and the adequacy of the quantitative level... View More
scope:
1.1 This test method measures the amount of light transmitted through a film of carbon black pigmented ethylene polymer.
1.2 After calculation of the amount of light and film thickness, an absorption coefficient is calculated.
1.3 Whenever two sets of values are presented, in different units, the values in the first set are the standard, while those in parentheses are for information only.
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.
