1.1This specification covers two classes of commercial quality round and shaped quenched and tempered steel spring wire intended especially for the manufacture of mechanical springs and wire forms. The quality level is lower than specialty spring quality (Specification A1000/A1000M) or valve spring quality (Specification A230/A230M).
1.2The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems can result in non-conformance with the standard.
1.3This 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.
