ASTM D – 12 Standard Test Method for Measuring the Nominal Thickness of Geosynthetics
Thickness is one of the basic physical properties used to control the quality of many geosynthetics. This test measures the changes in linear dimensions of specimens of known size, when exposed to specific conditions of elevated temperature and time.
