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. 2. Referenced Documents (purchase
separately) The documents listed below are referenced within the
subject standard but are not provided as part of the standard.
