This specification covers uncoated and four classes of round, metallic coated, cold-drawn, carbon steel wire rope in five strength levels. The following materials testing procedures shall be conducted: standard tensile testing; alternate tensile testing; torsion testing; and wrap testing. The wire diameter tolerances of uncoated, drawn-galvanized or drawn-Zn5 Al-MM, and final-galvanized or final-coated Zn5 Al-MM rope wires shall be described. Minimum breakage forces for the carbon steel wire rope shall also be presented. During torsion testing, varying amounts of load shall be applied to the wire being tested.
