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.
