    1. Scope

    1.1 This specification covers bare round copper-clad aluminum wire for electrical applications.

    1.2 Four classes of copper-clad aluminum wire are covered as follows:
    Class 10A—Nominal 10 volume % copper, annealed.
    Class 15A—Nominal 15 volume % copper, annealed.
    Class 10H—Nominal 10 volume % copper, hard-drawn.
    Class 15H—Nominal 15 volume % copper, hard-drawn.

    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.
