This part of EN 1366 describes the method to evaluate the performance of protective systems for electrical cable systems in order to maintain the circuit integrity under fire conditions to classify the protective system according to EN 13501-3 for the P classification. The test examines the behaviour of cable protection systems exposed to fire from outside. The tests specified in this standard are not aimed for assessing the performance of the fire protective system and the penetration seal for maintaining the requirements of the penetrated wall or ceiling (classification E / I). 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. This test procedure shall also be used to determine the functionality for optical and data cables in case of fire. The protective 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, and without fire protective systems around, are excluded (see CENELEC standard under development). This method is very different to EN 50200 for the PH classification, which is 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.
