This European Standard specifies a test method to evaluate the maintenance of circuit integrity of electric cables which have intrinsic resistance to fire under fire conditions, in order to classify the electric cable according to EN 13501-3 [2]. The test determines the survival time for circuit integrity of the electric cable when exposed to fire under the conditions of the EN 1363-1 standard time/temperature curve. This European Standard is used in conjunction with EN 1363-1. This European Standard applies to electric power and control cables with rated voltage up to and including 600/1 000 V. The cable is tested in a standardized representative installation condition. The test does not assess the performance of the cable management system. NOTE Optical and data cables could be tested using this method but do not form part of this European Standard as the verification procedures for such cables are still under development. This European Standard includes (Annex A) field of direct application and rules for extended application of test results (EXAP).
