1.1 This specification covers bare round copper-clad steel for the following applications: electrical, electronic, grounding, telecommunications, and other applications.
1.2 Four conductivities are covered as follows: 21, 30, 40, and 70 %.
1.3 Temper is designated as annealed.
1.4 The values stated in inch-pound or SI units are to be regarded separately as the standard. Each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. For conductor sizes designated by AWG, the requirements in SI units have been numerically converted from corresponding values stated or derived in inch-pound units. For conductor sizes designated by SI units only, the requirements are stated or derived in SI units.
This specification covers annealed bare round copper-clad steel wire for the following applications: electrical, electronic, grounding, telecommunications, and other applications. Four types of copper-clad steel wires according to their electrical conductivities are included. The wire shall consist of a core of homogeneous open-hearth, electric-furnace, or basic-oxygen steel with a continuous outer cladding of copper thoroughly bonded to the core throughout. The copper-clad steel wire shall conform to the specified requirements for: tensile strength, elongation, dimension (diameter), adhesion and surface defects, joints, finish, copper thickness, density, and electrical resistivity. Methods for measurement, inspection, and testing such as torsion (twist) test are detailed.
