ASTM A229/A229M-12 - 15.4.2012
 
1. Scope

1.1 This specification covers two classes of round and shaped quenched and tempered steel spring wire intended especially for the manufacture of mechanical springs and wire forms.

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 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.
