ASTM B609/B609M-12 PDF

1.1 This specification covers aluminum 1350-O (annealed), 1350-H12 or -H22 (¼ hard), 1350-H14 or -H24 (½ hard), 1350-H16 or -H26 (¾ hard) and 1350-H142 or -H242 (½ 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.
