    1. Scope

    1.1 This specification covers concentric-lay-stranded conductors made from round aluminum 1350-H19 (extra hard) wires and round aluminum-alloy 6201-T81 (hard: solution heat treated, cold worked, and then artificially aged) core wires for use as overhead electrical conductors (Explanatory Note 1).

    1.2 The values stated in inch-pound units are to be regarded as the standard with the exception of density. SI units shown are approximate.

    Note 1-Prior to 1975, aluminum 1350 was designated as EC aluminum. Note 2-The aluminum, alloy, and temper designations conform to ANSI H35.1. Aluminum 1350 and Alloy 6201 correspond to unified numbering system A91350 and A96201, respectively, in accordance with Practice E527. Note 3-A complete metric companion to Specification B524 has been developed-Specification B524M; however metric equivalents are included in this inch-pound specification for information only.
