Describes requirements and test methods for the construction and performance of cables.

This British Standard specifies requirements and test methods for the construction and performance of cables that:
have a thermosetting insulation of rated voltage 300/500 V;
emit limited amounts of smoke (see 15.5) and corrosive gases when subjected to relevant tests;
are primarily intended for use in walls, partitions and building voids;
have a screen that can carry the fault current required for a selected size and type of protective device, that operates within a given time if the cable is penetrated by a nail or similar fixing (see 16.4).

To achieve a satisfactory safety performance of the cable when installed, both the selection of protective device and the maximum current rating is critical.

NOTE 1 See Clause 12 for the requirements of the safe selection of protective devices and maximum current rating of cables.

It is applicable to 2-core, 3-core and 4-core cables with an uninsulated, full-size circuit protective conductor and metallic screening.

NOTE 2 A guide to the use of the cables specified in this British Standard is given in Annex A.
