|Publication Date:||10 April 2000|
|ICS Code (Steel wire, wire ropes and link chains):||77.140.65|
1.1 This specification covers round, uncoated, high tensile strength, hard-drawn steel spring wire, having properties and quality suitable for the manufacture of mechanical springs and wire forms subject to high static stresses or infrequent dynamic load, or both.
1.2 The 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 exact equivalents; therefore, each system must be used independent of the other.
