Standard Specification for Soft or Annealed Copper Wire
The following bibliographic material is provided to assist you with your purchasing decision:
This specification covers drawn and annealed or soft round bare copper wire for electrical purposes. The matterial shall be copper of such quality and purity that the finished product shall have the properties and characteristics prescribed. Tensile strength, elongation, and resistivity of the wires shall be determined. A micrometer caliper equipped with a vernier shall be used to measure the material dimensions. The wires shall be subjected to surface finish and shall conform to the particularized requirements.
Scope
1.1 This specification covers drawn and annealed or soft round bare copper wire for electrical purposes (see Explanatory Note 1).
1.2 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.
1.2.1 Exception—For density, resistivity and temperature, the values stated in SI units are to be regarded as standard.
