Anotácia textu normy ASTM A586-18 :
This specification covers zinc-coated parallel and helical steel wire structural strands for use where a high-strength, high-modulus, multiple-wire tension member is desired as a component part of a structure. Breaking strength is expressed as Grade 1 or 2, while, coating weight is expressed as Class A, B, or C. Strands shall be furnished with Class A weight zinc-coated wires throughout, but may be furnished with Class B or C weight wires as well where additional corrosion protection is required. The base metal shall be carbon steel manufactured by the open-hearth, basic-oxygen, or electric-furnace process Finished strands and the hard-drawn individual zinc-coated wires shall be coated by the hot-dip or electrolytic process. Specimens shall be tested and conform to values of the following physical requirements: nominal diameter, stress at specified extension under load, tensile strength, total elongation, ductility, and coating weight and adherence.

1.1 This specification covers metallic-coated steel wire structural strand, for use where a high-strength, high-modulus, multiple-wire tension member is desired as a component part of a structure. The strand is available with parallel or helical wire construction. 1.1.1 The strand is available with several metallic coating classes and with two strength grades, as described in Section 4. 1.2 The strand 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 as an option. 1.3 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. |
