This specification covers silver-coated, soft or annealed, round copper wire, intended for use in electrical equipment. The silver-coated wires are classified according to the total weight of the coated wires, namely; Class A, B, C, D, and E. Tensile strength test, resistivity test, weight of coating, and dimensional measurements shall be performed to conform to the requirements specified.
Область применения1.1 This specification covers silver-coated, soft or annealed, round copper wire, intended for use in electrical equipment, as follows:
1.2 Silver-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).
