This document specifies a test method for the determination of the breaking strength and elongation of nonwovens after conditioning or in the wet state, by the strip method. This test method describes two operating modes, named option A (thickness of the test specimen: 25 mm) and option B (thickness of the test specimen: 50 mm). This document specifies methods using tensile testing apparatus at constant rate of elongation (CRE) of the specimen. For information, constant force gradient (CFG) devices are covered in ISO 2062:2009, Annex A, as these instruments are still in use and their use may be subject to agreement between the interested parties.
