ISO 13934-1:2013(E) Textiles-Tensile properties of fabrics-Part 1:Determination of maximum force and elongation at maximum force using the strip method1 ScopeThis part of ISO 13934 specifies a procedure to determine the maximum force and elongation at maximum force of textile fabrics using a strip method.NOTE ISO 13934-2 describes the method known as the grab method. For informative references, see Bibliography.The method is mainly applicable to woven textile fabrics, including fabrics which exhibit stretch characteristics imparted by the presence of an elastomeric fibre, mechanical, or chemical treatment. It can be applicable to fabrics produced by other techniques. It is not normally applicable to geotextiles, nonwovens, coated fabrics, textile一glass woven fabrics, and fabrics made from carbon fibres or polyolefintape yarns (see Bibliography).The method specifies the determination of the maximum force and elongation at maximum force of test specimens in equilibrium with the standard atmosphere for testing, and of test specimens in the wet state.The method is restricted to the use of constant rate of extension (CRE) testing machines.2 Normative referencesThe following referenced documents are indispensable for the application of this document.
