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.
