Причина отмены This specification covered hard-drawn round copper alloy wires for electric conductors. The copper alloy wires were to be made in any one of ten distinct alloys designated 8.5 to 85 in accordance with their increasing conductivities or designated by assigned UNS numbers.

Formerly under the jurisdiction of Committee B05 on Copper and Copper Alloys, this specification was withdrawn in April 2023. This standard is being withdrawn without replacement due to its limited use by industry.

Реферат

This specification covers hard-drawn round copper alloy wires for electric conductors. The wires shall be made in any one of ten distinct alloys designated 8.5, 13, 15, 20, 30, 40, 55, 74, 80, and 85 in accordance with their increasing electrical conductivities. Specimens shall undergo tests to which they shall meet the required values for chemical composition, electrical resistivity, and mechanical and physical properties. The mechanical properties to be examined are elongation and tensile strength, while the physical properties in consideration are wire diameter, area, and density. The completed wire, to which no joints are to be made, shall be free from all imperfections not consistent with the best commercial practice.
