This part of IEC 60092 provides the basic requirements for the selection and installation of electrical cables intended for fixed electrical systems on board ships at voltages (U) up to and including Um 36 kV and also fibre optic cables..

The reference to fixed systems includes those that are subjected to vibration (due to the movement of the ship) or movement (due to motion of the ship) and not to those that are intended for frequent flexing.

Cables subject to frequent or continual flexing use shall be able to withstand the mechanical stress and the environment they are exposed to and are detailed in other IEC specifications e.g. IEC 60227 and IEC 60245. Flexible cables are frequently used for retractable thrusters, elevators, moving decks, cranes, shore connections and other moving applications on board ships.

The following types and applications of cables are not included:

optical fibre cables;

sub-sea and umbilical cables;

data, telecommunication and radio frequency cables;

the choice and installation of cables for use on offshore platforms;

The object of this test is to define a standard test method for thermoelectric electromotive force(e.m.f.).

Note: If different metals are attached at both ends and the temperatures where the metals are connected are held at different temperatures, current will flow in one direction in the circuit. The electromotive force that causes this current is called thermoelectromotive force.
