(Specification)Standard Performance Specification for Zippers for Dungarees, Jeans, and Work Trousers
Standard Performance Specification for Zippers for Dungarees, Jeans, and Work Trousers
ABSTRACT
This performance specification covers zippers to be used as fly closures in dungarees, jeans, and work trousers made from heavy denim or other durable fabric. Zippers covered here may be satisfactorily used for lighter weight denim and other fabrics as well, however, consideration should be given to the zipper size and slider type because of their effect on the appearance of the zipper installation area. Zippers shall be suitably sampled and tested, and shall adhere accordingly to the following requirements: element pull-off resistance; element slippage resistance; crosswise chain strength; bottom stop holding-stringer separation strength; top stop holding strength; slider lock holding strength (positive and ratchet lock); slider deflection and recovery after pull (deflection and permanent set); resistance to pull-off of slider pull; slider operability on chain; longitudinal dimensional change after laundering (normal and low shrinkage level); and colorfastness to laundering (color change and staining). It is recognized that for purposes of fashion or aesthetics the ultimate consumer may find acceptable trousers having zippers that do not conform to all of these requirements. Therefore, one or more of the requirements may be modified by agreement between the purchaser and the supplier.
SIGNIFICANCE AND USE
5.1 This specification serves as a guide for the purchase of zippers 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 the requirements listed in Table 1 of this specification.
5.3 It is recognized that for purposes of fashion or aesthetics the ultimate consumer may find acceptable dungarees, jeans, or work trousers, having zippers that do not conform to all of the requirements in Table 1. Therefore, one or more of the requirements listed in Table 1 may be modified by agreement between the purchaser and the supplier.
5.3.1 In such cases, and references to this specification shall specify that: This zipper meets Performance Specification D4465 except for the following characteristic(s).
5.4 Where no prepurchase agreement has been reached between the purchaser and the supplier, and in case of controversy, the requirements listed in Table 1 are intended to be used as a guide only. As noted in 5.3, ultimate consumer demands dictate varying performance parameters for any particular style of zipper.
5.5 The uses and significance of particular properties and test methods are discussed in the appropriate sections of the specified test methods.
SCOPE
1.1 This performance specification covers zippers to be used as fly closures in dungarees, jeans, and work trousers made from heavy denim or other durable fabric, approximately 475 g/m2 (14 oz/yd2).
1.2 Zippers covered by this specification may be satisfactory for lighter weight denim and other fabrics.
1.2.1 When lighter weight material is being used, consideration should be given to the zipper size and slider type because of their effect on the appearance of the zipper installation area.
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
