1.1 This specification covers round, zinc-5 % aluminum-mischmetal (Zn-5Al-MM) alloy-coated, steel core wire with three classes of Zn-5Al-MM coating used for mechanical reinforcement in the manufacture of aluminum conductors, steel reinforced (ACSR). 1.2 This specification covers wire of diameter from 0.0500 to 0.1900 in. or 1.27 to 4.82 mm, inclusive. 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
