Method of test for resistance to fire of larger unprotected power and control cables for use in emergency circuits Ingestion-build-53008 Part nine of BS EN1 Scope This European Standard specifies a test method for cables designed to have intrinsic resistance to fire and intended for use as emergency circuits. The standard is applicable to power and control cables for emergency circuits of rated voltage not exceeding 0,6 1 kV. The test method is intended for cables with an overall diameter exceeding 20 mm. Cables of smaller diameter shall be tested in accordance with EN 50200. The test method is based on
