The work of preparing International Stand
23、ards 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, in liaison with ISO, also ta
24、ke 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 task of technical committees i
25、s 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. Attention is drawn to the possibili
26、ty 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 13936-1 was prepared by Technical Committee ISO/TC 38, Te x t i l e s, Subcommittee SC 24, Conditioning atmospheres and physical tes
27、ts for textile fabrics. ISO 13936 consists of the following parts, under the general title Tex t i l e s Determination of the slippage resistance of yarns at a seam in woven fabrics: Part 1: Fixed seam opening method Part 2: Fixed load method Part 3: Needle clamp method ENISO139361:2004 1 Textiles D
28、etermination of the slippage resistance of yarns at a seam in woven fabrics Part 1: Fixed seam opening method 1S c o p e This part of ISO 13936 is intended for the determination of the resistance offered by thread systems of woven fabric, to slippage at a sewn seam. This method is not suitable for s
29、tretch fabrics or for industrial fabrics, e.g. beltings. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (incl

ENISO139361:20042 NOTE Seam slippage is a fabric property and should not be confused with seam strength. 3.4
34、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 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 adjace
35、nt 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 p l e An unseamed and a seamed part of a test specimen are separately extended by using a tensile testing machine, fitted with grab test jaws, to produce, in th
36、e case of the use of a chart recorder, two force/extension curves originating from the same abscissa. The force required to produce a specified distance between the curves, equivalent to a specified seam opening is determined. 5 Sampling Select samples either in accordance with the procedure laid do
37、wn 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 or
38、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 characterist
39、ics given in 6.1.2 to 6.1.8. 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 record
40、ed 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 at
41、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 . 6.1.6 The clamping device of the machine shall be positioned with the central point of the two jaws in the line of the applied force
42、, the front edges shall be at right angles to the line of applied force and their clamping faces shall be in the same plane. 1% 1mm 8s 1 50 mm/min 10 % 100 mm ENISO139361:2004 3 The jaws shall be capable of holding the test specimen without allowing it to slip and designed so that they do not cut or
43、 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 either s
44、mooth 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 with t
45、he 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 clamp sh
46、all be (preferably ), positioned with the wider direction of the clamp perpendicular to the line of application of the force; the front clamp shall be . 6.1.8 A device for recording force and extension is necessary if the tensile tester is not computer-controlled. 6.2 Equipment for cutting test spec
47、imens 6.3 Sewing machine, electrically operated, single needle, lock stitch, capable of producing stitch type 301 as described in ISO 4915:1991 (see Figure 1). This stitch type is formed with two threads: one needle thread and one bobbin thread. A loop of thread 1 is passed through the material from
48、 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 of the material being sewn. This stitch type is sometimes produced from a single thread, in which case the first stitch differs from subsequent stitches. A minimum of two stitches describes this
