ASTM B682-01

Standard Specification for Standard Metric Sizes of Electrical Conductors

ABSTRACT
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.
SCOPE
1.1 This specification 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 2--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 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, 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.
