Active Standard ASTM B856 | Developed by Subcommittee: B01.07
Book of Standards Volume: 02.03
Historical (view previous versions of standard)
This specification covers round wire concentric-lay-stranded aluminium conductors, steel supported (ACSS) for use as ovehead electrical conductors. Tests for mechanical and electrical properties of aluminum wires shall be made after stranding. The electrical resistivity shall meet the minimum resistivity specified for the wire after stranding.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification covers round wire concentric-lay-stranded aluminum conductors, steel supported (ACSS) for use as overhead electrical conductors (see Explanatory Note 1).
1.2 The values stated in inch-pound or SI units are to be regarded separately as standard. Each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. For conductor sizes designated by AWG or kcmil sizes, the requirements in SI units are numerically converted from the corresponding requirements in inch-pound units. For conductor sizes designation by AWG or kcmil, the requirements in SI units have been numerically converted from corresponding values stated or derived in inch-pound units. For conductor sizes designated by SI units only, the requirements are stated or derived in SI units.
