27、 Textiles Seam tensile properties of fabrics and made-up textile articles: Part 1: Determination of maximum force to seam rupture using the strip method Part 2: Determination of maximum force to seam rupture using the grab method IntroductionThis part of ISO 13935 has been prepared in the context of
28、 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 procedure for these standards agrees where appropriate. The results obtained by one of the
29、 methods should not be compared with those obtained by the other methods. See Bibliography for informative references.Where it is intended to compare the seam maximum force values of sewn seams with the fabric maximum force, it is important to use the same type of test, test conditions and test spec
30、imens in the tests in this part of ISO 13935 and ISO 13934-1 (see Bibliography).4DIN EN ISO 13935-1:2014-07 EN ISO 13935-1:2014 (E) 1 ScopeThis part of ISO 13935 specifies a procedure to determine the seam maximum force of sewn seams when the force is applied perpendicularly to the seam. This part o
31、f ISO 13935 specifies the method known as the strip test.NOTE ISO 13935-2 describes the method known as the grab test. For informative references see the Bibliography.The method is mainly applicable to woven textile fabrics, including fabrics which exhibit stretch characteristics imparted by the pre
32、sence 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-glass woven fabrics and fabrics made from carbon fibres or polyolefin tape yarns (see Bibli
33、ography).The sewn fabrics may be obtained from previously sewn articles or may be prepared from fabric samples, as agreed by the parties interested in the results.This method is applicable to straight seams only and not to curved seams.The method is restricted to the use of constant rate of extensio
34、n (CRE) testing machines.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

40、-1:20134 PrincipleA fabric test specimen of specified dimensions having a seam in the middle is extended perpendicularly to the seam at a constant rate until the seam ruptures. The maximum force to seam rupture is recorded.5 SamplingSelect samples either in accordance with the procedure laid down in
41、 the material specification for the fabric, or as agreed between the interested parties.If preparation of seams prior to testing is required, avoid test specimens from folded or creased areas, selvedges and areas not representative of the fabric.For seams obtained from previously sewn articles ensur
42、e that the test specimens contain seams in straight line only and are representative for the relevant seam type of the textile article. Record any details in the test report.6 Apparatus6.1 CRE machineMetrological confirmation system of the tensile-testing machine shall be in accordance with ISO 1001
43、2.The constant-rate-of-extension (CRE) machine shall have the general characteristics given in 6.1.1 to 6.1.6.6.1.1 The tensile-testing machine shall be provided with means for indicating or recording the force applied to the test specimen in stretching it to rupture. Under conditions of use, the ac
44、curacy of the apparatus shall be class 1 of ISO 7500-1. The error of the indicated or recorded maximum force at any point in the range in which the machine is used shall not exceed 1 %.6.1.2 If a class 2 tensile testing machine according to EN 10002-2 is to be used, this shall be stated in the test
45、report.6.1.3 If recording of force is obtained by means of data acquisition boards and software, the frequency of data collection shall be at least eight per second.6.1.4 The machine shall be capable of constant rate of extension of 100 mm/min, with an accuracy of 10 %.6DIN EN ISO 13935-1:2014-07 EN
46、 ISO 13935-1:2014 (E) 6.1.5 The machine shall be capable of setting the gauge length to (200 1) mm.6.1.6 The clamping device of the machine shall be positioned with the centre of the two jaws in the line of applied force, the front edges shall be at right angles to the line of applied force and thei
47、r clamping faces shall be in the same plane.The jaws shall be capable of holding the test specimen without allowing it to slip and designed so that they do not cut or otherwise weaken the test specimen.The faces of the jaws shall be smooth and flat, except that when, even with packing, the test spec
48、imen cannot be held satisfactorily with flat-faced jaws, engraved or corrugated jaws can be used to prevent slippage. Other auxiliary materials for use with either smooth or corrugated jaws to improve specimen gripping include paper, leather, plastics or rubber.It is recommended that serrated metal
49、faced jaws are used when testing fabrics with stretch properties. Different jaw face surfaces may lead to different elongation resultsNOTE If jaw breaks or slippage cannot be prevented with flat jaws, capstan jaws have often been found suitable.The jaws preferably should have a width of at least 60 mm but shall not be less than the width of the test specimen.6.2 Equipment for sewing defined seams.6.3 Equipment fo
