ASTM Committee D35 on Geosynthetics has revised D6637, “Standard Test Method for Determining Tensile Properties of Geogrids by the Single or Multi-Rib Tensile Method,” as D6637-10. The determination of the tensile force-elongation values of geogrids provides index property values. This test method shall be used for quality control and acceptance testing of commercial shipments of geogrids.
