This standard specifies the standardized nominal cross-sectional areas from 0.5 mm2 to 2 000 mm2, as well as numbers and diameters of wires and resistance values for conductors in electric cables and flexible cords.
It does not apply to conductors for telecommunication purposes, and it applies to conductors of special design only when stated in the specification for the type of cable. Conductors of special design are, for example, conductors for pressure cables, conductors in extra-flexible welding cables or in special types of flexible cables having the cores twisted together with unusually short lays.
