    This specification prescribes the recommended standard metric sizes of solid round electrical conductors. The standard diameters of metric sizes of wires are preferred numbers calculated in accordance with the conventional mathematical principles. The standard metric size of stranded conductors and equivalent cross-sectional areas shall be designated.

    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. Scope

    1.1 This specification covers and prescribes the recommended standard metric sizes of solid round electrical conductors.

    1.2 This specification prescribes the recommended standard metric size designations of stranded electrical conductors (see Explanatory Note 1).

    Note 1: Physical properties, construction requirements, and manufacturing tolerances for specific products should be included in individual product specifications developed in accordance with appropriate sizes in this specification.

    1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

    1.3.1 Exceptions — For conductor sizes designated 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. Rounded values appear in Table 1.

    (A) The inch diameters, square inch areas, and circular mil areas are rounded values calculated from the metric diameters.
