ASTM D 6637 : 2001 : R2009

1.1 This test method covers the determination of the tensile strength properties of geogrids by subjecting strips of varying width to tensile loading.

1.2 Three alternative procedures are provided to determine the tensile strength, as follows:

1.2.1 Method A—Testing a single geogrid rib in tension (N or lbf).

1.2.2 Method B—Testing multiple geogrid ribs in tension (kN/m or lbf/ft).

1.2.3 Method C—Testing multiple layers of multiple geogrid ribs in tension (kN/m or lbf/ft)

1.3 This test method is intended for quality control and conformance testing of geogrids.

1.4 The values stated in SI units are to be regarded as the standard. The inch-pound values stated in parentheses are provided for information only.

1.5 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
