1.1 This test method covers the determination of the amount of fabric stretch and fabric growth after a specified extension and held for a specified time.
1.2 While this test method can be used for any fabric, knit fabrics having high stretch are better measured by Test Method D2594.
1.3 This test method should not be used to measure the breaking strength and elongation of woven fabrics, which is covered in Test Methods D5034 and D5035.
1.4 The 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.
1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6 This 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.
