31、made-up textile articles Part 1: Determination of maximum force to seam rupture using the strip method1 ScopeThis part of ISO 13935 specinullies a procedure to determine the seam maximum force of sewn seams when the force is applied perpendicularlnull to the seam. This part of ISO 13935 specinullies
32、 the method known as the strip test.NOTE ISO 13935-2 describes the method known as the grab test. For informative references see the nullibliographnull.The method is mainlnull applicable to woven textile fabricsnull including fabrics which exhibit stretch characteristics imparted bnull the presence
33、of an elastomeric nullibrenull mechanical or chemical treatment . It can be applicable to fabrics produced bnull other techninullues. It is not normallnull applicable to geotextilesnull nonwovensnull coated fabricsnull textile-glass woven fabrics and fabrics made from carbon nullibres or polnullolen
34、ullin tape nullarns (see nullibliographnull).The sewn fabrics manull be obtained from previouslnull sewn articles or manull be prepared from fabric samplesnull as agreed bnull the parties interested in the results.This method is applicable to straight seams onlnull and not to curved seams.The method
35、 is restricted to the use of constant rate of extension (CRE) testing machines.2 Normative referencesThe following documentsnull in whole or in partnull are normativelnull referenced in this document and are indispensable for its application.
