The work of pr
24、eparing International Standards is normally carried out through ISO technical 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, i
25、n liaison with ISO, also take part in the work. ISO collaborates closely with 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 tas
26、k of technical committees is to prepare International Standards. Draft International 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. Attentio
27、n is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 13936-2 was prepared by Technical Committee ISO/TC 38, Te x t i l e s, Subcommittee SC 24, Conditioning a
28、tmospheres and physical tests for textile fabrics.

34、t the test and where the entire testing system is virtually free from deflection 3.2 grab test tensile test in which only the centre part of the specimen is gripped in the jaws 1) To be published. ENISO139362:20042 3.3 yarn slippage, seam slippage movement, in a woven fabric of weft yarns over warp
35、yarns (or warp yarns over weft yarns) as a result of a pulling action NOTE Seam slippage is a fabric property and should not be confused with seam strength. 3.4 warp slippage warp yarns slipping over weft yarns, i.e. the warp yarns are at right angles to the direction of pull 3.5 weft slippage weft
36、yarns slipping over warp yarns, i.e. the weft yarns are at right angles to the direction of pull 3.6 seam allowance distance between the seam line and the adjacent edges of the material 3.7 seam opening distance between the yarns which have been displaced on either side of the seam line 4P r i n c i
37、 p l e A strip of fabric is folded and stitched across its width. The strip is cut near the fold and a force is applied to the strip at right angles to the seam using grab-test jaws. The extent to which the seam opens is measured. 5 Sampling Select samples either in accordance with the procedure lai
38、d down in the material specification for the fabric, or as agreed between the interested parties. In the absence of specification, an example of a suitable sampling procedure is given in Annex A. An example of a pattern for cutting test specimens is given in Annex B. Avoid test specimens from folded
39、 or creased areas, selvedges and areas not representative of the fabric. 6 Apparatus and materials 6.1 CRE Machine 6.1.1 Metrological confirmation system of the tensile-testing machine shall be in accordance with ISO 10012. The constant-rate-of-extension (CRE) machine shall have the general characte
40、ristics given in 6.1.2 to 6.1.7. 6.1.2 The tensile-testing machine shall be provided with means for indicating or recording the force applied to the test specimen in extending it. Under conditions of use, the accuracy of the apparatus shall be class 1 of ISO 7500-1:. The error of the indicated or re
41、corded maximum force at any point in the range in which the machine is used shall not exceed , and the error of the indicated recorded jaw separation shall not exceed . 6.1.3 If recording of force is obtained by means of data acquisition boards and software, the frequency of data collection shall be
42、 at least . 6.1.4 The machine shall be capable of constant rate of extension of , with an accuracy of . 6.1.5 The machine shall be capable of setting the gauge length to . 1% 1mm 8s 1 50 mm/min 10 % 100 mm ENISO139362:2004 3 6.1.6 The clamping device of the machine shall be positioned with the centr
43、al point of the two jaws in the line of the applied force, the front edges shall be at right angles to the line of applied force and their 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 cu
44、t or otherwise weaken the test specimen. The faces of the jaws shall be smooth and flat, except that when, even with packing, the test specimen cannot be held satisfactorily with flat-faced jaws, engraved or corrugated jaws can be used to prevent slippage. Other auxiliary materials for use with eith
45、er smooth or corrugated jaws to improve specimen gripping include paper, leather, plastics or rubber. 6.1.7 The area of the fabric clamped during the test shall be . This area can be achieved by either method a) or method b) as described below. a) The rear clamp shall be (preferably ), positioned wi
46、th the wider direction of the clamp perpendicular to the line of the application of the force; the front clamp shall be of the same dimensions positioned perpendicular to the first so that the wider direction of the clamp is parallel to the direction of the application of the force. b) The rear clam

A loop of thread 1 is passed through the material from the needle side and is interlaced with thread on the other side. Thread 1 is pulled back so that the interlacing comes midway between the surfaces
