This specification covers round, aluminum-clad steel core wire used for mechanical reinforcement in the manufacture of aluminum conductors, aluminum-clad steel reinforced. The base metal shall be steel produced by the openhearth, electric-furnace, or basic-oxygen process and shall be of such composition that the finished clad wire shall have the properties and characteristics prescribed in this specification. The aluminum used for cladding shall have a purity and quantity sufficient to meet thickness and resistance requirements of this specification. The material shall conform to the required tensile properties such as stress, tensile strength, and elongation. The aluminum-clad steel core shall undergo elongation test, tension test, and torsion test. The elongation test shall be determined by an extensometer equipped with a vernier or other instrument reading. In the torsion test, a small tensile load shall be applied to the specimen during testing. The specimen shall be twisted by rotating one of the vises in the same direction until fracture occurs.
