Defines 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.

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 EN13501‑3 . The test determines the survival time for circuit integrity of the electric cable when exposed to fire under the conditions of the EN1363‑1 standard time/temperature curve. This European Standard is used in conjunction with EN1363‑1 . This European Standard applies to electric power and control cables with rated voltage up to and including 600/1000V. The cable is tested in a standardized representative installation condition. The test does not assess the performance of the cable management system. NOTE Optical fibre cables and copper communication cables could be tested using this test method, however verification procedures for such cables were still under development when this document has been circulated for vote (2015-07-24). This European Standard includes field of direct application ( AnnexA) and rules for extended application of test results (EXAP) ( AnnexB). The selection of cables to be tested for classification of a family is given in AnnexB. In case the selection of the cables does not comply with AnnexB, the test results are only applicable to the tested cables.
