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 Paper courtesy of the 63 rd IWCS Technical Symposium, Providence, Rhode Island, USA, November 2014.
