ASTM D 5970/D5970M : 2016 : R2021

1.1This test method covers evaluating the deterioration in tensile strength and strain after outdoor exposure.

1.2The deterioration is assessed as a reduction in strength and strain at failure from the unexposed geotextile.

1.3The specific location of the light and weather exposure is made on the basis of a site-specific decision between the parties involved.

1.4The 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.

1.5This 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.

1.6This 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.
