ASTM A906 covers the standard specification for grade 80 and grade 100 alloy steel chain slings for overhead lifting. To meet this standard, the mechanical properties of the chain must meet the ASTM requirements. A391 covers the test practices for determining the proof load, breaking force, and elongation of steel wire.
