Salient Characteristics

Note General. The individual item requirements shall be as specified herein and in accordance with the applicable ASTM standard. In the event of any conflict between the requirements of this CID and the applicable ASTM standard, the former shall govern.

Materials. The composition of the copper shall conform to ASTM B49.

Construction.
Solid wire.
Solid wires shall conform to and cover the range of wire sizes in the applicable ASTM standard specified in table I. The diameters and cross sectional areas shall be in accordance with ASTM B258. Solid wire of 33 through 56 AWG shall be in accordance.

Splices. Splices shall not be made in wire, except as permitted by the applicable ASTM standard. Splices shall be so constructed and distributed throughout the wire that the diameter, configuration, resistance, flexibility, and mechanical strength of the completed wire shall not be adversely affected.

Performance. All wire shall comply with the requirements of the applicable ASTM standard.

Elongation of 33 through 44 AWG wires only. Wire sizes 33 through 40 AWG shall have a minimum elongation of 15 percent and wire sizes 41 though 44 AWG shall have a minimum elongation of 10 percent. The percentage of elongation shall be calculated from the travel distance of the testing machine’s gripping jaw at the instant of break of a 10 inch wire sample elongated at the rate of 12 inches ±1 inch per minute. A test that results in a break within 0.25 inches of either gripping jaw shall be repeated with a new sample.
