    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 40—HSNominal 40 % conductivity hard-drawn, and

    1.2.4 Class 40ANominal 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.
