Scope

This Standard specifies the nominal cross-sectional areas, in the range 0.5 mm2
to 2 500 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 and stranded copper,
aluminium and aluminium alloy conductors in cables for fixed installations and
flexible copper conductors.
This Standard does not apply to conductors for telecommunication purposes.
The applicability of this Standard to a particular type of cable is as specified in
this Standard for the type of cable.
Unless indicated to the contrary in a particular clause, this Standard relates to
the conductors in the finished cable and not to the conductor as made or
supplied for inclusion into a cable.
Informative annexes are included giving supplementary information covering
temperature correction factors for resistance measurement (Annex B) and
dimensional limits of circular conductors (Annex C).
