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 high-strength hard-drawn,

1.2.2''Class 30HS-A'''Nominal 30'''% conductivity high-strength annealed,

1.2.3''Class 40HS'''Nominal 40'''% conductivity high-strength hard-drawn, and

1.2.4''Class 40HS-A'''Nominal 40'''% conductivity high-strength 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.

1.4''This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
