1.1This test method covers equipment, specimen preparation techniques, and procedures for evaluating the dispersion of carbon black in polyolefin geosynthetics containing less than 5 % carbon black by weight.

1.2This test method allows for a qualitative evaluation of carbon black agglomerates and other inclusions in polyolefin geosynthetics. This evaluation is based on carbon black dispersion size calculated area within microscopic fields of view.

1.3The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.4This 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:This test method is for the evaluation of carbon black dispersion. This test method does not support or evaluate the distribution of carbon black.
