1、Designation: D 3657 03Standard Specification forZipper Dimensions1This standard is issued under the fixed designation D 3657; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indica

2、tes the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification establishes standard dimensions forzippers of all materials for specified size designation; forequivalency, in inch-pound and metric units, of

3、zipper lengthand length tolerances, of tape width and width tolerances, andof tape end lengths.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used inde

4、pendently of the other. Combiningvalues from the systems may result in non-conformance withthe standard.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and

5、health practices and determine the applica-bility of regulatory limitations prior to use.2.

Sampling4.1 Sample the lot and select the number of specimens asdirected in Methods D 2060.5. Dimensions and Permissible Varia

7、tions5.1 Zippers shall conform to the dimensions listed in Tables1-4.5.2 Tables 2 and 3 include tolerances which represent tradepractice and are in common use. The tolerances are not uniformbetween sizes because of differing requirements of the zippersbased on their normal end-use.5.3 Table 2, withi

8、n a size, has uniform plus tolerances.Minus tolerances increase nonuniformly with increasing lengthbecause that is accepted trade practice based on the require-ments of the end products in which the zippers are installed.5.3.1 Because zipper chain is composed of a series ofelements with a prescribed

9、 pitch and each element must remaincomplete to function, it is impossible to manufacture a zipperdeliberately to an exact stated length. Therefore a shipment ofzippers of a stated length will not likely average the statedlength. Both the lot average length and the length of individualzippers should

10、fall within the tolerances in Table 2.5.4 Table 4 shows the metric conversion for standardinch-pound unit tape end lengths. Tape end length tolerancesare not shown due to widely varying end-use requirements andinherent zipper manufacturing dimension variations. Toler-ances to be observed should be a
