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 D1775.
