Standard Specification for High-Strength Zinc-Coated (Galvanized) Steel Core Wire for Use in Overhead Electrical Conductors

ABSTRACT
This specification covers the standard requirements for round, high-strength, zinc-coated (galvanized), steel core wire with Class A zinc coating used for mechanical reinforcement in the manufacture of special steel reinforced aluminum and aluminum-alloy conductors. The base metal shall be steel produced by the open-hearth, electric-furnace, or basic-oxygen process and the wire shall be cold drawn and coated with zinc. Joints may be made at any stage of processing prior to final cold drawing by the electric butt-weld or flash-welding process. Chemical analysis shall be conducted; wherein, the steel shall conform to the chemical composition requirements for carbon, manganese, phosphorus, sulfur, and silicon. The zinc-coated steel core wire shall conform to the tensile strength and elongation requirements which shall be obtained using a tensile test method. The material shall also undergo wrap and adherence tests; wherein, the wire shall be capable of being wrapped in a close helix without cracking or flaking.
SCOPE
1.1 This specification covers round, high-strength, zinc-coated (galvanized), steel core wire with Class A zinc coating (GA3) for use in overhead electrical conductors.  
1.2 This specification covers wire of diameter from 0.0500 in. to 0.1900 in. inclusive or 1.27 mm to 4.82 mm inclusive.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
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.

Standard Specification for Tin-Coated, Copper-Clad Steel Wire for Electronic Application

ABSTRACT
This specification covers tin-coated, copper-clad steel wires for electronic applications. The four classes of steel wires considered here are: hard-drawn wires with 30% nominal conductivity (Class T30HS); annealed wires with 30% nominal conductivity (Class T30A); hard-drawn wires with 40% nominal conductivity (Class T40HS); and annealed wires with 40% nominal conductivity (Class T40A). Specimens shall go through tests and shall adhere to specified requirements for dimensions, electrical resistivity, tensile strength, and coating continuity and adherence.
SCOPE
1.1 This specification covers tin-coated copper-clad steel wire for electronic application.  
1.2 Four classes of tin-coated copper-clad steel wire are covered as follows:  
1.2.1 Class T30HS—Nominal 30 % conductivity, hard-drawn,  
1.2.2 Class T30A—Nominal 30 % conductivity, annealed,  
1.2.3 Class T40HS—Nominal 40 % conductivity, hard-drawn, and  
1.2.4 Class T40A—Nominal 40 % conductivity, annealed.  
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.  
1.3.1 Exception—The SI values for resistivity and volume are to be regarded as standard.  
1.4 The following safety hazards caveat pertains only to the test method portion, Section 6, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. (Warning—Consideration should be given to toxicity and flammability when selecting solvent cleaners.)  
1.5 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.
