Description

ASTM B231/B231M-11

Historical Standard: Standard Specification for Concentric-Lay-Stranded Aluminum 1350 Conductors

ASTM B231/B231M

Scope

1.1 This specification covers aluminum 1350-H19 (extra hard), 1350-H16 or -H26 (¾ hard), 1350-H14 or -H24 (½ hard), and 1350-H142 or -H242 (½ 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 Note 1 and Note 2).

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

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 Standard H35.1/H35.1M. Aluminum 1350 corresponds to Unified Numbering System A91350 in accordance with Practice E527.

Note 3—Sealed conductors that are intended to prevent longitudinal water propagation and are further covered/insulated are also permitted within the guidelines of this specification.
