EVS-EN IEC 60228:2024

IEC 60228 specifies the nominal cross-sectional areas, in the range 0,5 mm2 to 3 500 mm2, for conductors in electric power cables and cords of a wide range of types. Requirements for numbers and sizes of wires and resistance values are also included. These conductors include solid, stranded and Milliken, copper, aluminium and aluminium alloy conductors in cables for fixed installations and flexible copper conductors.

IEC 60228 does not apply to conductors for telecommunication purposes. The applicability of this document to a particular type of cable is as specified in the standard for the type of cable. Unless specified otherwise in a specific clause, IEC 60228 relates to the conductors in the finished cable and not to the conductor as made or supplied for inclusion into a cable. Conductors described in the standard are specified in metric sizes.

Informative annexes provide supplementary information covering temperature correction factors for resistance measurement (Annex B) and guidance on dimensional limits of circular conductors (Annex C).

IEC 60228:2023 has been approved in Europe as EN IEC 60228:2024 without any changes.
