ASTM B609/B609M-12(2021)

Standard Specification for Aluminum 1350 Round Wire, Annealed and Intermediate Tempers, for Electrical Purposes

ABSTRACT
This specification covers annealed and intermediate tempered round aluminum wires suitable for electrical purposes like stranding into conductors or for solid single conductors, either bare or insulated. The tempers covered here are 1350-O, 1350-H12 or 1350-H22, 1350-H14 or 1350-H24, 1350-H16 or 1350-H26, and 1350-H142 or 1350-H242. Materials shall be made from drawing stock in which the manufacturer shall have the option of producing the intermediate tempers by either strain-hardening only, by strain-hardening and partial annealing. The wires shall adhere to standard nominal diameters, cross-sectional areas, masses per unit length, and densities. Wires shall also be tested to evaluate their conformance to specified values of tensile strength and electrical resistivity.
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 (see Table 1 or Table 2).    
1.2 The values stated in inch-pound units or SI units are to be regarded separately as standard. The values in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.  
1.2.1 For density, resistivity, and temperature, the values stated in SI units are to be regarded as standard.
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 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.
