1.1 This specification covers aluminum 1350-H19 (extra hard), 1350-H16 or -H26 (3/4 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.

1.3 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.


This specification covers aluminum1350-H19, 1350-H16 or -H26, 1350-H14 or -H24, and 1350-H142 or -H242 bare compact-round concentric-lay-stranded conductors made from round or shaped wires for use as uninsulated electric conductors or in covered or insulated electrical conductors. Joint shall be cold-pressure welded or electric-butt, cold-upset welded. The conductors shall conform to the required construction values of number of wires, nominal compact conductor diameter, nominal cross-sectional area and nominal DC resistance. Tests for the mechanical and electrical properties of wire composing the conductor shall be made before stranding and the conductors shall conform to the required values of breaking strength and rated strength.
