This part of EN 1366 describes a method to evaluate the maintenance of circuit integrity of electrical cable systems and associated components (connectors, glands, junctions, mountings, etc.) under fire conditions to classify the protective system according to EN 13501-3. The test examines the behaviour of cable protection systems exposed to fire from outside.
This standard is used in conjunction with EN 1363-1.
The test results apply to fire protective systems for electrical cable systems rated for voltages up to 1 kV.
NOTE This test procedure may be used to determine the functionality for optical and data cables in case of fire but this does not form part of the classification procedure.
The protection system may include ventilation devices, inspection hatches, fixed or removable lids etc.
The tests specified in this standard are not aimed for assessing the performance of sprayed or painted coatings (e. g. intumescent or ablative coating, plastic film, epoxy resin) and similar protective layers (e.g. wrap, bandage) applied directly on the cables or bus bars as fire protective system. Also cables and bus bars with intrinsic resistance to fire are excluded.
This method is very different to EN 50200 and also to IEC 60331-11, -21, -23 and -25, which are not designed for fire protective systems for electrical cable systems.
This test method is not applicable for cabinets for electrical accessory containing bus systems, relays or similar.
