Historical (view previous versions of standard)
This specification covers bare round copper-clad aluminum wire for electrical applications. Four classes of copper-clad aluminum wire are covered such as Class 10A, Class 15A, Class 10H, Class 15H. The wire shall consist of a core of aluminum with a continuous outer cladding of copper throughly bonded to the core throughout and shall be of such quality as to meet the requirements of this specification. The copper-clad aluminum wire shall conform to the tensile strength and elongation requirements. The electrical resistivity shall be measured. The copper-clad aluminum wire, when tested shall be free from seams or splits. They shall be free from cladding delamination. The finished wire shall contain no joints or splices. The density of the wire shall be taken for calculating mass/unit length, cross section and so forth.
