Designation: A679/A679M − 17Standard Specif i cation forSteel Wire, High Tensile Strength, Cold Drawn 1This standard is issued under the f i xed designation A679/A679M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specif i cation covers round, uncoated, high tensilestrength, cold drawn steel spring wire, having properties andquality suitable for the manufacture of mechanical springs andwire forms subject to high static stresses or infrequent dynamicload, or both.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system are not exact equivalents; therefore, each systemshall be used independently of the other. Combining valuesfrom the two systems may result in non-conformance with thestandard.1.3 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards, Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade (TBT) Committee.2.
