This European Standard describes the method to evaluate the performance of protective systems for electrical cable and busbar 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 method is very different to EN 50200 for the PH classification and also to IEC 60331 11, IEC 60331 21, IEC 60331 23, and IEC 60331 25, which are not designed for fire protective systems for electrical cable systems. This standard should be 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. The test
