ASTM D2594-20

Standard Test Method for Stretch Properties of Knitted Fabrics Having Low Power

1.1 This test method covers the measurement of fabrics that exhibit high stretch and good recovery from low tension. Fabric stretch is measured when a known load is applied. Fabric growth is evaluated after a known extension is applied and subsequently removed.

1.2 The procedures for fabric stretch and fabric growth can be used together, or individually.

1.3 While this test method can be used for a knit fabric, fabrics intended for support or other applications are better evaluated using other test methods: D3107, D4964, D6614.

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

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.
