1.1This test method covers the determination of the seam strength of geotextiles, using a wide specimen.

1.2The long term performance of a seaming technique is not addressed by this test method. This test method will provide data to indicate the short term seam strength that can be achieved for each particular geotextile and seam assembly construction. To assess the long term performance of a seaming technique, it is possible to use Practice D6389, using this test method to determine the anticipated strength reduction in the initial, short term wide-width tensile strength (Test Method D4595) results.

1.3The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.4This 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.
