ASTM D 4884/D4884M : 2022

1.1This test method covers the determination of the factory and field seam strength of geotextiles, using a wide specimen and wet and dry specimens.

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 are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
