    1. Scope

    1.1 This specification covers copper clad aluminum rectangular bar for electrical (bus) applications.

    1.2 Six classes of copper-clad aluminum bar are covered as follows:

    Class 20A—Nominal 20 volume % copper, annealed.

    Class 25A—Nominal 25 volume % copper, annealed.

    Class 30A—Nominal 30 volume % copper, annealed.

    Class 20H—Nominal 20 volume % copper, hard-worked.

    Class 25H—Nominal 25 volume % copper, hard-worked.

    Class 30H—Nominal 30 volume % copper, hard-worked

    1.3 The values stated in inch-pound units are to be regarded as the standard, except for resistivity and density, where the SI units are the standard. The values given in parentheses are for information only.

    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.
