This International Standard specifies a method, known as the "strip" method, for the determination of the breaking strength and elongation at break of woven textile fabrics (except woven elastic fabrics). The method is applicable to unimpregnated fabrics and to fabrics that have been impregnated with sizing or stiffening materials but not to fabrics coated with rubber or plastics. The method provides for the determination of the breaking strength and elongation at break specimens in equilibrium with the standard atmosphere for testing, and of specimens in the wet state. The method authorizes the use of the following types of testing machine in common use for measuring breaking strength and elongation of fabrics: a) constant-rate-of-specimen-extension (CRE); b) constant-rate-of-traverse (CRT); c) constant-rate-of-load (CRL). The three types of testing machines do not necessarily give the same results for the same fabric. The type of tester to be used must, therefore, be agreed upon by all parties interested in the test results, and must be reported. As it has been found that the breaking strengths obtained on different types of tester agree best when the time-to-break is the same, the method provides for testing at specifictimes-to-break, and to rates of extension, traverse, or loading are not specified.
