1、Designation: D4465 05 (Reapproved 2015)Standard Performance Specification forZippers for Dungarees, Jeans and Work Trousers1This standard is issued under the fixed designation D4465; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision,
2、the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () 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 trous
3、ers madefrom heavy 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

Terminology3.1 Definitions:3.1.1 denim, na durable woven twill fabric, usually of allcotton or a blend of cotton and man-made fibers, made from avariety of yarn numbers, and in various fabric weights, colors,designs, and finishes.3.1.1.1 DiscussionTraditionally,
7、 denim is made with in-digo blue dyed cotton warp and undyed or tinted filling. Denimfabrics are used for many types of garments including workclothes, sportswear, dresswear, and home furnishings.3.2 Definitions of Terms Specific to This Standard:3.2.1 jeans, na style of trousers made of a twill fab
8、ric usedas sportswear and work clothing.3.2.2 dungaree, ntrousers made from denim and designedfor general heavy work wear.3.2.3 trouser, na garment that closes at the waist andcovers the lower body to the crotch and each leg from the waistto the ankle.3.3 For other textile terminology used in this s
9、pecification,refer to Terminology D123. For definitions of zipper termsused in this specification, refer to Terminology D2050.4. Specification Requirements4.1 The properties of zippers for dungarees, jeans and worktrousers shall conform to the specification requirements inTable 1.5. Significance and
10、 Use5.1 This specification serves as a guide for the 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 re
11、cognized that for purposes of fashion or aestheticsthe 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
12、purchaser and the supplier.5.3.1 In such cases, and references to this specification shallspecify that: This zipper meets Performance SpecificationD4465 except for the following characteristic(s).5.4 Where no prepurchase agreement has been reachedbetween the purchaser and the supplier, and in case o
13、fcontroversy, the requirements listed in Table 1 are intended tobe used as a guide only. As noted in 5.3 ultimate consumerdemands dictate varying performance parameters for anyparticular style of zipper.1This performance specification is under the jurisdiction of ASTM CommitteeD13 on Textiles and is

Take the specimens, andperform the tests on zippers as received by the garmentmanufacturer or on zippers removed from unused garments.6.3.1 If the method does not specify
19、the number of speci-mens and there has been no prior agreement, use the proce-dures in Practice D2905 to determine the number of specimensper unit in the laboratory sample when using a reliable estimateof the variability of individual observations on similar materi-als in the users laboratory under
20、conditions of single-operatorprecision. The number of specimens per unit in the laboratorysample shall be such that the user may expect at the 95 %probability level that each test result is not more than 5 % ofthe average above or below the true average for the unit in thelaboratory sample.7.
