Scope

1.1 This test method covers the determination of the amount of fabric stretch, fabric growth, and fabric recovery of fabrics woven in whole or in part from stretch yarns after a specified tension and extension.

1.2 This test method is intended for use with woven fabrics exhibiting high stretch (greater than 12 percent) and good recovery properties from low tension (up to 360 g/cm or 2 lb/in. of fabric width). When agreed upon, this test method can be used for fabrics woven in whole or in part from non-stretch yarns that exhibit limits within the stretch characteristics shown above.

1.3 This test method allows the use of two tension options commonly used in the textile industry; 1.35 kg (3 lb.) and 1.8 kg (4 lb). Several calculations are included for fabric stretch, fabric growth and fabric recovery, and can be used individually when required by individual specifications.

1.4 This test method should not be used to measure breaking elongation of woven fabrics which is covered in Test Method D 5035.

1.5 The values stated in either SI units 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.

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