6.2 IEC
In 2013 IEC adopted the draft EN50618 on request of IEC
TC82 as a basic paper to start to work out an IEC standard
for photovoltaic wires.
This is now published as a committee draft IEC62930.
The IEC draft is 95 per cent identical to EN50618.
6.2.1 The difference to EN50618
The main difference between EN 50618 and IEC 62930
is that in the IEC standard class two conductors are
permitted for use for fixed installations.
7 What is new in EN50618 and IEC
62930
7.1 Design
There are no great differences in the design requirements
of these new standards. Notice, however, the definition of
black as preferred jacket colour.
Minor changes are in the required layer thicknesses, which
are slightly increased.
7.2 Test requirements
Note that the material testing procedures have been widely
changed by adapting IEC60811 ”Electric and optical fibre
cables – Test methods for non-metallic materials”.
• All test samples now have to be taken from finished
cables
• It is not permitted to conduct material tests on
extruded tapes or moulded plates
