11、6, Uncontrolled Copy, (c) BSI BSI 2006 iiiBS 3084:2006ForewordThis British Standard has been prepared by Technical Committee TCI/66, Apparel and interior textiles. It supersedes BS 3084:1992, which is withdrawn. A list of organizations represented on TCI/66 can be obtained on request to its secretar

12、y.The first edition of this British Standard was published in January 1959. It was not possible at that time to include tests for the pin and socket fitting of open-end fasteners, and the main purpose of the 1963 revision was to cover that type of fitting. In the 1981 edition, fasteners were coded n

13、ot according to their size, as they were in previous editions, but to their performance levels, so that fasteners could be selected taking into account their end use, not their size. This approach has been followed in subsequent editions. BS 3084:1992 incorporated Amendment 1 to BS 3084:1981 and int

14、roduced technical changes and corrections to conform to current practice. The 2006 edition represents a full review of the standard to meet the needs of current users. The test methods have been extended to accommodate the practice of testing to failure, rather than merely terminating each test when

15、 the specified performance level has been met, as in earlier editions. Testing to failure is the more common method currently as, combined with the application of statistical techniques, it generates more meaningful information about the capabilities of products and processes, compared with the alte

16、rnative pass or fail results. Nothing in this standard precludes this practice.Similarly, previous versions recommended a sampling procedure based on batch sizes, but inspection by variables is considered to be more appropriate than inspection by attributes, so the annex that formerly dealt with thi

17、s has been retained only as an informative annex. Users wishing to continue using such sampling plans are recommended to consult BS 6001 for sampling procedures for inspection by attributes. Previous editions specified additional colour fastness and dimensional stability requirements for fasteners t

18、o be sold direct to the public. These requirements have now been incorporated as minimum requirements for all fasteners, to reflect the needs of current users.This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application.Co

20、c) BSI BSI 2006 1BS 3084:2006IntroductionThe different types of slide fasteners are defined by the material of the elements (teeth), which form their fastener chains. They can be of metallic, moulded plastic or monofilament plastic construction.Metallic elements can be produced from flat or profiled

21、 wire and are usually clamped around the edge of a beaded textile tape. An alternative approach is to cast metallic elements directly onto such a tape. Similarly, plastic elements can be moulded onto a beaded textile tape. Such cast or moulded elements might have projections on which the slider oper

22、ates to reduce abrasion of the textile tape.Plastic coil fasteners have nylon or polyester monofilaments that are wound into coils to form engaging elements. The coils can be attached to the face of flat textile tapes by sewing. Alternatively, the coils can be woven or knitted into the textile tapes

23、 as they are constructed. Monofilament plastic elements can also be of the meander type, which straddle the tape edge.Typical fastener chain types are shown in Figure 1.1 ScopeThis British Standard specifies performance levels and test methods for the following characteristics of slide fasteners mad

24、e from interlocking components mounted on textile tapes: strengths of puller attachment, closed-end, top stop, open-end fastener box, reciprocating mechanism, closed fastener when extended laterally, open-end attachment when extended laterally, slider lock, and open-end fastener single stringer slid

25、er retention. NOTE The tests specified in Annexes B to J have been specifically devised to permit their direct application to finished fasteners with a view to giving the user reasonable assurance that a fastener conforming to the requirements of this British Standard can satisfactorily fulfil its i

26、ntended purpose. Annex K gives information about sampling procedures for bulk quantities of fasteners.In addition, performance levels are also specified for colour fastness to washing, dry cleaning and water, and for dimensional stability to washing and dry cleaning. This British Standard is applica

27、ble to slide fasteners for general use and is not applicable to slide fasteners for aeronautical or other specialist purposes (slide fasteners for aeronautical purposes are covered by BS 3F 121).Licensed Copy: Wang Bin, na, Fri Jul 14 03:18:18 BST 2006, Uncontrolled Copy, (c) BSIBS 3084:20062 BSI 20
