CONTAINED IN VOL. 02.03, 2017 Describes silver-coated, soft or annealed, round copper wire, intended for use in electrical equipment.

1.1This specification covers silver-coated, soft or annealed, round copper wire, intended for use in electrical equipment, as follows:

1.1.1Class A—Wire whose silver coating is at least 1.25 % of the total weight of the coated wire.

1.1.2Class B—Wire whose silver coating is at least 2.50 % of the total weight of the coated wire.

1.1.3Class C—Wire whose silver coating is at least 4.00 % of the total weight of the coated wire.

1.1.4Class D—Wire whose silver coating is at least 6.10 % of the total weight of the coated wire.

1.1.5Class E—Wire whose silver coating is at least 10.00 % of the total weight of the coated wire.

1.2Silver-coated wire having different minimum percentages of silver by weight may be obtained by mutual agreement between the manufacturer and the purchaser. For information purposes the thickness of coating in microinches provided by the percentages listed above is shown in Table 1 (Explanatory Note 1).

1.3The 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.

1.3.1Exceptions—The SI values for density, resistivity, and volume are to be regarded as standard.

1.4The following precautionary caveat pertains only to the test method section of this specification: 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 and health practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements see 8.4.1.2 and Explanatory Note 2.

1.5This 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.
