(Specification)Standard Specification for Aluminum 1350 Round Wire, Annealed and Intermediate Tempers, for Electrical Purposes
Standard Specification for Aluminum 1350 Round Wire, Annealed and Intermediate Tempers, for Electrical Purposes
SCOPE
1.1 This specification covers aluminum 1350-O (annealed), 1350-H12 or -H22 (1/4 hard), 1350-H14 or -H24 (1/2 hard), 1350-H16 or -H26 (3/4 hard) and 1350-H142 or -H242 (1/2 hard), suitable for stranding into conductors or for solid single conductors, either bare or insulated. (Table 1).
1.2 The values stated in inch-pound units are the standard with the exception of resistivity. The SI equivalents of inch-pound units may be approximate.
Note 1-Prior to 1975, aluminum 1350 was designated as EC-aluminum.
Note 2-The aluminum and temper designations conform to ANSI H35.1. Aluminum 1350 corresponds to Unified Numbering System A91350 in accordance with Practice E 527.
