EVS-EN 50577:2015
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 standard time/temperature curve.  This European Standard is used in conjunction with EN 1363-1. This European Standard applies to cables of rated voltages up to and including 600/1 000 V and control cables with rated voltage. The cable is tested in a standardized installation condition. The test does not assess the performance of the cable management system.
