ASTM B231M-95

Standard Specification for Concentric-Lay-Stranded Aluminum 1350 Conductors [Metric] (Withdrawn 1999)

SCOPE
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 made 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). Note 1-Prior to 1975, aluminum 1350 was designated EC aluminum. Note 2-The aluminum and temper designations conform to ANSI H35.1(M). Aluminum 1350 corresponds to Unified Numbering System A91350 in accordance with Practice E257. Note 3-This specification is the metric companion of Specification B231. 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.
