Standard Test Method for Absorption Coefficient of Ethylene Polymer Material Pigmented with Carbon Black
 N D3349

Annotation

This test method measures the amount of light transmitted through a film of carbon black pigmented ethylene polymer.

After calculation of the amount of light and film thickness, an absorption coefficient is calculated.

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.

*A Summary of Changes section appears at the end of this standard.
