备注:
范围:1.1 This specification covers aluminum 1350-H19 (extra hard), 1350-H16 or -H26 (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 corr
