Applies to emission and immunity aspects of EMC for electrical and electronic apparatus intended for use on railway rolling stock. The frequency range considered is from d.c. to 400 GHz. At present, testing is not defined for frequencies above 1 GHz. The application of tests shall depend on the particular apparatus, its configuration, its ports, its technology and its operating conditions. This standard takes into account the internal environment of the railway rolling stock and the external environment of the railway, and interferences to the apparatus from equipment such as hand-held radio transmitters. If a port is intended to transmit or receive for the purpose of radio communication then the emission and immunity limits in this standard at the communication frequency do no apply. This standard does not apply to transient emissions when starting or stopping the apparatus. The objective of this Standard is to define limits and test methods for electromagnetic emssions and immunity test requirements in relation to conducted and radiated disturbances. These limits and test represent essential electromagnetic compatibility requirements. Emission requirements have been selected to 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. The levels do not however cover extreme cases which may occur with an extremely low probability of occurence in any location. Specific requirements which deviate from this Standard shall be specified. Test requirements are specified for each port considered. These specific provisions are additional to the general provisions in prEN 50121-1.
