1、Designation: A 641/A 641M 03Standard Specification forZincCoated (Galvanized) Carbon Steel Wire1This standard is issued under the fixed designation A 641/A 641M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last revi
2、sion. A number in parentheses indicates the year of last reapproval.A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This specification covers soft, medium, and
3、hard temperzinc-coated (galvanized) carbon steel wire in coils for generaluse.1.2 The supplementary requirements of this specificationcover zinc-coated weights masses for nails, staples, and wirefrom which nails and staples are cut and formed.1.3 This specification is applicable to orders in eitheri
4、nch-pound units (as A 641) or SI units (as A 641M). Valuesstated in either inch-pound units or SI units are to be regardedseparately as the standard. Within the text, the SI units areshown in brackets. The values stated in the two systems are notexact equivalents; therefore, each system shall be use
5、d inde-pendent of the other, without combining values in any way.1.4 This specification and some referenced specificationsare expressed in both inch-pound and SI units. If the orderspecifies the applicable “M” specification designation, theproduct shall be furnished to SI units.1.5 The text of this
