    Abstract

    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.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. Scope

    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.

    1.5 The following precautionary statement pertains to the test method portion only, Section 7, of this specification: This standard does not purport to address all of the safety concerns, if any associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
