ASTM D 5278/D5278M : 2009 : R2013

1.1This test method determines the elongation characteristics of narrow elastic fabrics made from natural or man-made elastomers, either alone or in combination with other textile fibers, when tested with a static load testing procedure before or after laundering.

1.2The use of this test method requires the selection of, or mutual agreement upon, the effective static load at which the test results will be determined.

1.3Laundering procedures used will be those specified in Test Method AATCC 135 for 3 washing and drying cycles.

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 may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.5This standard does not purport to address all of the safety problems, 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.
