scope:

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 1000 MHz. 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.
