ASTM B901-04(2021) - 1.2.2021
 
1. 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), 1350-H142 or -H242 (1/2?hard), and aluminum alloy 8XXX series as listed in Specification B800 for tempers O and H1X or H2X, bare stranded conductors composed of one or more roller shaped or die compressed layers of helically layed wires. The conductors are for general use for electrical purposes (Explanatory Notes 1 and 2).

Note 1:?For the purposes of this specification, single input wire (SIW) construction is defined as follows: a stranded conductor design methodology that varies the number of wires within a range of conductor sizes in order to permit that range of conductor sizes to be constructed from a single wire size.

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 2:?Prior to 1975, aluminum 1350 was designated as EC aluminum.

Note 3:?The aluminum and temper designations conform to ANSI H35.1. Aluminum 1350 corresponds to Unified Numbering System A91350 in accordance with Practice E527. Aluminum alloys in the 8000 series correspond to Unified Numbering System A98XXX in accordance with Practice E527.

Note 4:?This specification also permits conductors for use as covered or insulated electrical conductors.

Note 5:?Sealed conductors, which are intended to prevent longitudinal water propagation and are further covered/insulated, are also permitted within the guidelines of this specification.

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.
