1. Scope

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

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

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