(Test Method)Standard Test Method for Tension and Elongation of Elastic Fabrics (Constant-Rate-of-Extension Type Tensile Testing Machine)
Standard Test Method for Tension and Elongation of Elastic Fabrics (Constant-Rate-of-Extension Type Tensile Testing Machine)
SCOPE
1.1 This test method covers the measurement of tension and elongation of wide or narrow elastic fabrics made from natural or man-made elastomers, either alone or in combination with other textile yarns, when tested with a constant-rate-of-extension (CRE) type tensile testing machine.
Note 1-For determination of similar testing using the constant-rate-of-load (CRL) type tensile testing machine, refer to Test Method D 1775.
1.2 The use of this test method requires the selection of, or mutual agreement upon, tension(s) and elongation(s) at which the test results will be determined.
1.3 Laundering procedures require mutual agreement on the selection of temperature and number of washing cycles and drying cycles to be used.
1.4 The values stated in 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 must be used independently of the other, without combining values in any way.
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 and health practices and determine the applicability of regulatory limitations prior to use.
