|Publication Date:||10 September 2001|
|ICS Code (Steel wire, wire ropes and link chains):||77.140.65|
1.1 This specification covers carbon steel chain for such applications as railroad cars, construction, industrial uses, load binding, and general purposes other than overhead lifting.
Note 1-This specification does not cover carbon steel chain for sprocket applications.
1.2 Three classes of carbon steel chain are covered:
1.2.1 Grade 30-Proof coil chain.
1.2.2 Grade 43-High test chain.
1.2.3 Grade 70-Transport chain.
1.3 The values stated in either acceptable metric units or in other units shall be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining values in any way.
