1.1 This specification covers Aluminum 1350 bar for electric conductors in the tempers shown in . 1.2 Aluminum and temper designations are in accordance with ANSI H35.1/H35.1(M). The equivalent Unified Numbering System designation is A91350 in accordance with Practice E 527. Note 1 - For Alloy 6101 bus conductors, refer to Specification B 317/B 317M. Note 2Prior to 1975, Aluminum 1350 was designated as EC aluminum. 1.3 A complete metric companion to Specification B 236 has been developed-B 236M; therefore, no metric equivalents appear in this specification. 1.4 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.
