1.1 This specification covers aluminum 1350-H19 (extra hard), 1350-H16 or -H26 ( 3/4 hard), 1350-H14 or -H24 (1/2 hard), and 1350-H142 or -H242 (1/2 hard), bare concentric-lay-stranded conductors constructed with a straight round central wire surrounded by one or more layers of helically layed wires. The conductors are for general use for electrical purposes (Explanatory Notes 1 and 2).
1.2 The SI values for resistivity are regarded as standard. For all other properties the inch-pound units are regarded as standard and the SI 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 Standard H35.1. Aluminum 1350 corresponds to Unified Numbering System A91350 in accordance with Practice E527. Note 3-A complete metric companion to Specification B231 has been developed-Specification B231M. Note 4-Sealed conductors that are intended to prevent longitudinal water propagation and are further covered/insulated are also permitted within the guidelines of this specification.
