10、 direction of the Aerospace Standards Committee, is one of a series for textiles of a quality suitable for aerospace purposes. During its preparation account has been taken of the fact that basic quality requirements are included in the latest edition of BS F 100. This standard specifies requirement
11、s for braided nylon cord with specified dimensional stability manufactured from twist set yarn as previously defined in Ministry of Defence DTD Specification 5620, which this standard replaces. It differs from DTD Specification 5620 primarily in that prestabilized yarns are now permitted. Braided ny
12、lon cord with unspecified dimensional stability, manufactured from non-twist set yarn and/or twist set yarn, as previously defined in Ministry of Defence DTD Specification 5620, is specified in BS F 135. The quality assurance authority referred to in this standard is as stated in the contract or ord
13、er, or the accredited representative of the authority stated, as instructed by the prime constractor. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standar
14、d does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages 1 to 8, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporate
15、d. This will be indicated in the amendment table on the inside front cover.

16、r braided nylon cord with specified dimensional stability, manufactured from twist set yarn for aerospace purposes. NOTE 1The titles of the publications referred to in this standard are listed on the inside back cover. NOTE 2The latest revision of an Aerospace Series standard is indicated by a prefi
17、x number. 2 General requirements In addition to the requirements specified in clauses 3 to 6 of this standard, the following clauses of the latest edition of BS F 100 shall apply. 3 Yarn 3.1 The cord shall be manufactured from continuous filament bright nylon 6.6 yarns, which shall have the tenacity
18、 and extension at break as given in Table 1. Table 1 Yarn properties 3.2 The yarn shall comply with the properties given in Table 1 to the satisfaction of the quality assurance authority when assessment is based on the manufacturers quality control procedures. NOTEIn case of dispute the tenacity and
19、 extension at break results shall be determined by the method of test and sampling given in BS 1932-1 and BS 2010. 3.3 The yarn shall not be sized. 4 Construction and properties 4.1 General 4.1.1 The cords shall be braided from yarns which comply with the relevant requirements of Table 1 to Table 7.
20、 SectionTitleRequirements and tests 1GeneralAll requirements. 2aQuality requirementsRequirements for the manufacture of cordage only. Requirements for dyed textiles except for those relating to fabric intended for coating. Requirements for dimensions and tolerances of lengths of cordage except those
21、 relating to laid ropes. Requirements for freedom from corrosive impurities (see section 4). Requirements for freedom from defects of braided cordage only 3Physical testsTests for mass of narrow fabrics and cordage. Tests for breaking strength and extension under load. Tests for sheath slackness and
22、 core looping of braided cordage. Tests for plaits per unit length in braided cordage. 4Chemical testsIf required by section 2, further tests for freedom from corrosive impurities. a It is not intended that section 2 tests should be performed on each cord batch. The frequency of these tests should b

24、02:21 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS F 132:1987 2 BSI 02-2000 4.1.2 The construction and properties of the finished cords shall comply with Table 2 to Table 7, 4.2, 4.3, 4.4, clause 5 and clause 6. 4.2 Dimensional stability 4.2.1 Unstabilized yarns shall be subjected to a setting trea
25、tment after twisting and prior to braiding. NOTE 1The purpose of the setting treatment is to ensure the production of cords with consistent dimensional stability. Setting may be carried out by means of steam or dry heat provided the finished cord complies with 4.2.5. NOTE 2Prestabilized yarns may re
26、quire a setting treatment after twisting in order to comply with BS F 100 for twist liveliness. 4.2.2 Unstabilized and prestabilized yarns shall not be used in the same cord. 4.2.3 Cord SB 603 shall be made from yarns which have been heat set after twisting. 4.2.4 The cord shall not be set after bra
27、iding. 4.2.5 The shrinkage of the finished cords in water shall not be greater than 3.0 % when measured in accordance with Appendix A. 4.3 Identification threads All cords shall contain coloured threads in the sheath to denote dimensionally stable cords, the colour being indicated in a footnote to T
28、able 2 to Table 7. Coloured identification threads shall consist of whole ends which are part of the cord construction specified in Table 2 to Table 7. 4.4 Sheath slackness and core looping Finished cords constructed as given in Table 2, Table 3 and Table 4 shall exhibit a maximum of 3 mm sheath sla
29、ckness, and shall be free from core looping. 5 Finish 5.1 General The cord shall be supplied in one of the following conditions: a) undyed; b) dyed. NOTEWhen dyed cord is required, an increase in the mass per unit length of 10 % over that specified in Table 2 to Table 7 is permitted. 5.2 Dyeing 5.2.
30、1 Where dyeing is required the colour shall be specified by reference to a British Standard, e.g. BS 381C, or otherwise by pattern. 5.2.2 Where dyeing is required the yarns from which the cord is manufactured shall be dyed. Dyeing of the cord shall not be permitted after manufacture. 6 Identificatio
31、n Cords shall be identified, for ordering purposes, by the number of this British Standard, i.e. BS F 132:19871), together with the cord designation and, if required dyed, the colour. NOTEThis identification may be codified. For example, cord CA 102, required NATO green may be identified as BS F 132
32、/CA 102/BS 381C No. 285. 1) Marking BS F 132:1987 on or in relation to a product represents a manufacturers declaration of conformity, ie a claim by or on behalf of the manufacturer that the product meets the requirements of the standard. The accuracy of the claim is therefore solely the responsibil
33、ity of the person making the claim. Such a declaration is not to be confused with third party certification of conformity, which may also be desirable.
