The work of preparing International Standards is normally carried out through ISO technica

20、l committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely wit

21、h the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft Interna

22、tional Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be

23、 the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.The first edition of this International Standard ISO 13934-1 was prepared by the European Committee for Standardization (CEN) in collaboration with ISO Technical Committee TC 38, Textiles,

24、in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).ISO 13934-1 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 24, Conditioning atmospheres and physical tests for textile fabrics.This second edition cancels and replaces the first

25、 edition (ISO 13934-1:1999), of which it constitutes a minor revision.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 maxi

27、. tensile properties, seam tensile properties, tear properties, seam slippage. The procedure for these standards agrees where appropriate. The results obtained by one of the methods should not be compared with those obtained by the other methods. ISO 2013 All rights reserved vBS EN ISO 13934-1:2013B

28、S EN ISO 13934-1:2013Textiles 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

29、 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 chem

30、ical 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 Bibliography).The method specifies the determination o

31、f 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 reference
