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.

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.

1.3 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.

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.
