This document applies to emission and immunity aspects of EMC for electrical and electronic apparatus intended for use on railway rolling stock. prEN 50121 3 2:2025 applies for the integration of apparatus on rolling stock. The test frequency range defined in this document is considered to ensure the electromagnetic compatibility of the apparatus in the whole frequency range from 0 Hz (DC) to 400 GHz. The application of tests depends on the particular apparatus, its configuration, its ports, its technology and its operating conditions. This document takes into account the internal environment of the railway rolling stock and the external environment of the railway, and interference to the apparatus from equipment such as hand-held radio-transmitters. This document does not apply to transient emissions when starting or stopping the apparatus. The objective of this document is to define limits and test methods for electromagnetic emissions and immunity test requirements in relation to conducted and radiated disturbances. These limits and tests represent essential electromagnetic compatibility requirements. Emission requirements have been selected so as to ensure that disturbances generated by the apparatus operated normally on railway rolling stock do not exceed a level which could prevent other apparatus from operating as intended. Likewise, the immunity requirements have been selected so as to ensure an adequate level of immunity for rolling stock apparatus. Test requirements are specified for each port considered. AC and DC traction power ports (see Table A.2) are not covered in this document.
