    1. Scope

    1.1 This specification covers aluminum 1350-H19 (extra hard), 1350-H16 or -H26 ([n ]hard), 1350-H14 or -H24 (1/2 hard) and 1350-H142 or -H242 (1/2 hard) bare compact-round concentric-lay-stranded conductors made from round or shaped wires for use as uninsulated electrical conductors or in covered or insulated electrical conductors. These conductors shall be composed of a central core surrounded by one or more roller or die compacted layers of helically applied wires (Explanatory Note 1 and Note 2).

    1.2 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.

    Note 1—Prior to 1975, aluminum 1350 was designated as EC aluminum.
    Note 2—The aluminum and temper designations conform to ANSI Standard H35.1. Aluminum 1350 corresponds to Unified Numbering System A91350 in accordance with Practice E527.
