1、Designation: D 4465 05Standard Performance Specification forZippers for Dungaress, Jeans and Work Trousers1This standard is issued under the fixed designation D 4465; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last

2、 revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This performance specification covers zippers to be usedas fly closures in dungarees, jeans and work trousers madefrom he

3、avy denim or other durable fabric, approximately 475g/m2(14 oz/yd2).1.2 Zippers covered by this specification may be satisfac-tory for lighter weight denim and other fabrics.1.2.1 When lighter weight material is being used, consider-ation should be given to the zipper size and slider type becauseof

4、their effect on the appearance of the zipper installation area.1.3 The values stated in SI units are to be regarded as thestandard. The values in parentheses are for information only.2.

Specification Requirements4.1 The properties of zippers for dungarees, jeans and worktrousers shall conform to the specification requirements inTable 1.5. Significance and Use5.1 This specification serves as a guide for th

10、e purchase ofzippers to be used for dungarees, jeans or work trousers.5.2 Upon agreement between the purchaser and the supplier,zippers intended for this end-use should meet all of therequirements listed in Table 1 of this specification.5.3 It is recognized that for purposes of fashion or aesthetics

11、the ultimate consumer may find acceptable dungarees, jeans orwork trousers, having zippers that do not conform to all of therequirements in Table 1. Therefore, one or more of therequirements listed in Table 1 may be modified by agreementbetween the purchaser and the supplier.5.3.1 In such cases, and

12、 references to this specification shallspecify that: This zipper meets Performance SpecificationD 4465 except for the following characteristic(s).5.4 Where no prepurchase agreement has been reachedbetween the purchaser and the supplier, and in case ofcontroversy, the requirements listed in Table 1 a

13、re intended tobe used as a guide only. As noted in 5.3 ultimate consumerdemands dictate varying performance parameters for anyparticular style of zipper.5.5 The uses and significance of particular properties andtest methods are discussed in the appropriate sections of thespecified test methods.1This
