1.1This specification covers bare round copper-clad steel wire for electronic application.
1.2Four classes of copper-clad steel wire are covered as follows:
1.2.1Class 30HS—Nominal 30 % conductivity hard-drawn,
1.2.2Class 30A—Nominal 30 % conductivity annealed,
1.2.3Class 40HS—Nominal 40 % conductivity hard-drawn, and
1.2.4Class 40A—Nominal 40 % conductivity annealed.
1.3The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are in SI units.
