【国外标准】 Standard Specification for Metallic-Coated Steel Structural Wire Rope

This specification covers zinc-coated steel structural wire rope, prestretched or nonprestretched for use where a high-strength, relatively flexible prefabricated zinc-coated multiple-wire tension member is desired as a component part of a structure. The wire rope is furnished with Class A weight zinc-coated wires throughout. It can be furnished with Class B weight or Class C weight zinc-coated outer wires or Class B weight or Class C weight zinc-coated wires throughout where additional corrosion protection is required. The steel shall conform to the following tensile requirements: tensile strength; bend-free or kink-free test specimens; stress at extension under load; elongation; ductility; weight of zinc coating; adherence of coating; and finish. The weight of the zinc coating shall be determined by a stripping test made on the individual wires prior to fabrication of strand. When specified, the wire rope shall be prestretched. The prestretched rope shall meet the required minimum modulus of elasticity.1.1 This specification covers metallic-coated steel structural wire rope, prestretched or nonprestretched for use where a high-strength, relatively flexible prefabricated metallic-coated multiple-wire tension member is desired as a component part of a structure.1.2 The wire rope is furnished with Class A weight zinc or zinc-aluminum alloy-coated wires throughout. It can be furnished with Class B weight or Class C weight zinc-coated outer wires or Class B weight or Class C weight zinc-coated wires throughout as an option.1.3 Units—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.1.4 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.
