IEC 60840:1988

Specifies test requirements for power cables for fixed installations with extruded insulation of the types listed in Sub-clause 1.4 for rated voltages, U, above 30 kV (Um = 36 kV) up to and including 150 kV (Um = 170 kV). The requirements apply to cables for usual conditions of installation and operation, but not to special cables, such as submarine cables, for which modifications to the standard tests may be necessary or special test conditions may need to be devised. Tests for accessories are not included in this standard.
