This document specifies a test method for the determination of the breaking force and elongation of nonwovens using a strip method in conditioned or wet state. This test method describes two procedures, Option A (width of test specimen: 25 mm) and Option B (width of test specimen: 50 mm). This document specifies methods using constant rate of specimen extension (CRE) tensile testers. Constant rate of loading (CRL) instruments is covered, for information, in ISO 2062:2009, Annex A, in recognition of the fact that these instruments are still in use and can be used by agreement. This document has been prepared by Technical Committee ISO/TC 38 "Textiles" in collaboration with Technical Committee CEN/TC 248 "Textiles and textile products", the secretariat of which is held by BSI (United Kingdom). The responsible national standardization committee is Working Committee NA 106-02-10 AA "Spulerei, Spinnereimaschinen und Nonwoven; SpA zu ISO/TC 72/SC 1, ISO/TC 72/SC 3 und ISO/TC 38/WG 9" ("Spinning and winding machinery and nonwoven; German mirror Committee of SpA zu ISO/TC 72/SC 1, ISO/TC 72/SC 3 und ISO/TC 38/WG 9") at DIN Standards Committee Textiles and Textile Machinery (Textilnorm).
