This part of EN ISO 13934 specifies a procedure for the determination of maximum force of textile fabrics known as the grab test.
The method is mainly applicable to woven textile fabrics. It may be applicable to fabrics produced by other techniques. It is not normally applicable to woven elastic fabrics, geotextiles, nonwovens, coated fabrics, textile-glass woven fabrics and fabrics made from carbon fibres or polyolefin tape yarns (see annex D).
The method specifies the determination of the 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.
This part of EN ISO 13934 has been prepared in the context of several test methods for determination of certain mechanical properties of textiles using mainly tensile testing machines, e.g. tensile properties, seam tensile properties, tear properties, seam slippage.
The procedures for these International Standards agree where appropriate. The results obtained by one of the methods should not be compared with those obtained by the other methods. See annex D for informative references.
This edition cancels and replaces ISO 5082:1982.
EN ISO 13934 consists of the following parts, under the general title Textiles - Tensile
properties of fabrics:
- Part 1: Determination of maximum force and elongation at maximum force using the strip method
- Part 2: Determination of maximum force using the grab method
