ASTM B803/B803M-22 - 1.10.2022
 
1. Scope

1.1?This specification covers round, high strength, zinc5 % aluminum-mischmetal (Zn5AlMM) alloy-coated, steel core wire with one class of Zn5AlMM coating (MA3) for use in overhead electrical conductors.

1.2?This specification covers wire of diameter from 0.0500 in. to 0.1900 in. inclusive or 1.27 mm 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.
