This specification covers bare hard-drawn round copper-clad steel wire. The surface of the wire shall be smooth and free from imperfections not consistent with good commercial practice. The wire shall conform to the tensile requirements. Specimens shall be twisted to destruction and shall not reveal under test any seams, pits, slivers, or surface imperfections of sufficient magnitude to indicate inherent defects or imperfections in the wire. The electrical resistance of the wire shall be determined by resistance measurements. The finished wire shall contain no joints or splices made at finished size.

1.1 This specification covers bare hard-drawn round copper-clad steel wire for electrical purposes (Note 1).

Note 1—Wire ordered to this specification is not intended for redrawing. If wire is desired for this purpose, consult the manufacturer.

1.2 Four grades of wire are specified, designated as follows (Note 2): Grade 40 HS, Grade 40 EHS, Grade 30 HS, and Grade 30 EHS.

Note 2—The grades covered by this specification correspond to the following commercial designations:
Grade 40 HS, High Strength, 40 % Conductivity.
Grade 40 EHS, Extra High Strength, 40 % Conductivity
Grade 30 HS, High Strength, 30 % Conductivity.
Grade 30 EHS, Extra High Strength, 30 % Conductivity.

1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
