ASTM International Committee D35 on Geosynthetics has developed a new standard that is an important step toward the improvement of filtration design for non-woven geotextiles. The standard, D 7178 , Practice for Determining the Number of Constrictions “, m, ” of Non-Woven Geotextiles as a Complementary Filtration Property, will provide engineers and researchers a common basis for accurate determination of an important products property. Practice D 7178 is under the jurisdiction of Subcommittee D35.03 on Permeability and Filtration. Practice D 7178 describes the procedure used along with existing test methods to determine the number of…
