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 and Option B, for carrying out nonwoven material tensile tests. These two procedures use two types of specimens which are listed below, and three alternative types of testing machines are also listed below. CRE is the instrument of choice. Type of specimen: a) Option A 25 mm strip tensile b) Option B 50 mm strip tensile Style of tensile testing machine: a) Constant-rate-of-extension (CRE) b) Constant-rate-of-load (CRL) c) Constant-rate-of-traverse (CRT) SI values are regarded as the official standard system of measurement for this standard procedure. If other systems of measurement are used in place of SI units their values must be reported independently. Systems of measurement must not be combined in any way, but shall be regarded and reported separately. NOTE INDA has sponsored studies comparing both options A and B. Studies indicated that if option A was performed using option B s 50 mm wide material, the result for both options would harmonize, giving the same results, regardless of the other machine settings.
