This specification covers uninsulated metallic-coated copper conductors for use in hookup wire for electronic equipment. The coating of the solid conductors and the wires composing stranded conductors shall conform to the coating requirements. Unless otherwise specified, all coated conductors shall be furnished in the annealed temper. The elongation of Type I conductors shall be as specified in the reference material. For Type II stranded conductors 22 AWG and smaller, the test shall be performed on the whole conductor and the elongation measured when the first strand of the conductor breaks. Solid conductors shall conform to the requirements for Type I conductors, while stranded conductors shall conform to the requirements for Type II conductors. The direction and length of lay of the outside layer of stranded conductors are presented. The test methods to determine the conformance to coating, elongation, and electrical resistance requirements are presented in details.
1.1 This specification covers uninsulated metallic-coated copper conductors for use in hookup wire for electronic equipment.
1.2 The SI values for density are to be regarded as standard. For all other properties, the inch-pound values are to be regarded as the 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.
