【国外标准】 Standard Specification for Carbon Steel Wire for Wire Rope

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.1.1 This specification covers uncoated and metallic coated classes of round, cold-drawn, carbon steel wire for wire rope in five strength levels. This specification specifies:1.1.1 Dimensional tolerances,1.1.2 Mechanical characteristics,1.1.3 Chemical composition requirements,1.1.4 Coating requirements (if applicable), and1.1.5 Packaging requirements.1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
