1.1 This specification covers Aluminum 1350 bar for electric conductors in the tempers shown in Table 1. 1.2 Aluminum and temper designations are in accordance with ANSI H35.1. The equivalent Unified Numbering System designation is A91350 in accordance with Practice E 527. For Alloy 6101 bus conductors, refer to Specification B 317. Note 1 Prior 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.
