scope:

Commented versions are a valuable improvement upon the conventional IEC Redline Version (RLV). These versions are designed to facilitate a clearer understanding of the revisions made between the prior and current editions of a publication. This enhanced product package incorporates both the most recent edition of the document and the annotated redline version. This combined offering provides users with an easily accessible means to track and comprehend the alterations and additions that have been made, thereby enhancing the utility and effectiveness of the publication for its intended audience.

This document 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.

This document 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 particular clause, this document 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 this document 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).
