Users of this British Standard are advised to consider the desirability of third party certification of product conformity with this British Standar
10、d based on testing and continuing surveillance, which may be coupled with assessment of a suppliers quality systems against the appropriate Part of BS5750. Enquiries as to the availability of third party certification schemes will be forwarded by BSI to the Association of Certification Bodies. If a
11、third party certification scheme does not already exist, users should consider approaching an appropriate body from the list of Association members. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct
12、 application. Compliance with a British Standard does not itself confer immunity from legal obligations. In particular, attention is drawn to the Textile Products (Indications of Fibre Content) Regulations S.I. 1986 No. 26. Summary of pages This document comprises a front cover, an inside front cove

14、ies requirements for cotton webbings used in the manufacture and maintenance of load carrying and other equipment for military and other personnel. NOTEThe titles of the publications referred to in this standard are listed on the inside back cover. 2 Definitions For the purposes of this Part of BS71
15、41 the following definitions apply. 2.1 narrow fabric any fabric made by interlacing fibres or yarns which (in the UK) does not exceed450mm in width. In the USA and for the purpose of the Combined Nomenclature of the European Community for tariff purposes, the upper limit of width is300mm. A charact
16、eristic of a narrow fabric is that its edges are an essential feature NOTESeveral items inTable 1 are theoretically too wide to be classified as narrow fabrics. They are included, however, as their end-use and other parameters group them with the other items. 2.2 needleloom a shuttleless loom in whi
17、ch the weft is drawn from a stationary supply and introduced into the shed in the form of a double-pick by a weft insertion needle. The weft is retained at the opposite selvedge by the action of knitting, or by the introduction of a locking thread from a separate supply 2.3 needleloom selvedge (NL s
18、elvedge) the selvedge opposite to that from which the weft is inserted in a narrow fabric needleloom NOTEUsually, this selvedge is formed by knitting together successive double-pick weft loops, sometimes in combination with, or exclusively by means of, a locking thread from a stationary supply. Alte
19、rnatively, the locking thread may be supplied from a small spool arranged to be passed through the extremities of the weft loops. 2.4 pick a single operation of the weft insertion mechanism in weaving. Thus the “double-pick” inserted by a needleloom is defined as one pick 2.5 selvedge when used with
20、out qualification, a longitudinal edge of a fabric formed during weaving, with the weft not only turning at the edges but also passing continuously across the width of the fabric from edge to edge 2.6 shuttleloom a weaving machine that uses a shuttle to insert the weft 2.7 stitch finish a finish act
21、ing as a lubricant which is applied to fabrics to facilitate the movement of sewing thread and/or penetration of a sewing needle through the fabric 2.8 tape a woven narrow fabric, generally plain-weave, used in non-loadbearing applications and for the reinforcing of fabrics to resist wear and deform
22、ation 2.9 weave the pattern of interlacing of warp yarns and weft yarns in a woven fabric 2.10 webbing a woven narrow fabric, the prime function of which is loadbearing NOTEWebbing is generally of a coarse weave and often has multiple plies. 3 Material The webbing, except for the catch thread, shall
23、 be made wholly from cotton. 4 Manufacture 4.1 Webbings shall comply with the appropriate specification given inTable 1. 4.2 The yarns shall be three-fold, five-fold or nine-fold, as specified inTable 1. The number of turns per metre shall be as follows when determined in accordance with BS2085: a)
24、three-fold yarn, not less than390; b) five-fold yarn, not less than270; c) nine-fold yarn, not less than200. NOTESingles yarns of62tex folded as specified above have been found suitable. 4.3 The minimum breaking force of the yarns before weaving shall be as follows when determined in accordance with
25、 BS1932-1: a) three-fold yarn,22N; b) five-fold yarn,35N; c) nine-fold yarn,58N. 4.4 The finished webbings shall contain not more than1% by mass of grease, soap, filling or any admixture used to increase the mass per metre or to give substance or firmness. NOTEIn cases of dispute, the percentage sho
26、uld be determined in accordance with BS3477.BS 7141-2:1991 2 BSI 11-1999 Table 1 Construction and performance Reference number MoD pattern number Width (determined in accordance with BS1930) Width tolerance Minimum ends in width (determined in accordance with BS2862) Minimum picks per 100mm (determi
