Organization: IEC
Publication Date: 1 October 2007
Status: active
Page Count: 18
ICS Code (Cables): 29.060.20
scope:

This standard provides a range of stnadard tests which may be required for protective coverings consisting of extruded oversheaths when teh coverings, in addition to protecting underlying metallic layers against corrosion, are required to fulfill special functions, for the following types a) and b), such as:

a) insulated sheath systems:

i) where special bonding is employed to reduce sheath losses, resulting in a sheath voltage under full load conditions;

ii) where to cable sheath can be isolated from earth to permit a voltage to be applied to the oversheath to check the integrity of the covering;

b) uninsulated sheath system:

i) protection against corrosion of the underlying metal layer where preservation of the metal layer is of particular importance and/or the combination of the particular metal and the cable environment would give rise to a serious risk of corrosion.

The tests required in this standard are only appropriate to particular conditons and use and do not have to be implemented for normal conditions and use. Guidance on their implementation will be provided in the relevant cable specification.
