1. Scope

1.1 This specification covers bare round copper-clad steel wire for electronic application.

1.2 Four classes of copper-clad steel wire are covered as follows:

1.2.1 Class 30HS—Nominal 30 % conductivity hard-drawn,

1.2.2 Class 30A—Nominal 30 % conductivity annealed,

1.2.3 Class 40HS—Nominal 40 % conductivity hard-drawn, and

1.2.4 Class 40A—Nominal 40 % conductivity annealed.

1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are in SI units.
