Test Method Title
Standard Test Method for Microscopic Evaluation of the Dispersion of Carbon Black in Polyolefin Geosynthetics
Reference Number
ASTM D5596
Material
Geomembrane
Test Property
carbon black dispersion
Description of Test
This test method consists of two parts: microtome specimen preparation and 2 microscopic evaluation. 4.1.1 Microtome Specimen Preparation--A sample is clamped in the sample holder, which can be raised or lowered precisely in increments of approximately 1 um. A rigid knife is slid manually across the sample so that the specimens range in thickness from 8 to 20 um. These thin sections are then evaluated microscopically using a visual comparison between each random field of view. Rf and the carbon dispersion reference chart. Each Rf is classified or rated according to the arrangement of categories on the reference chart.
