Product Overview ( Overview ) :
Emission and immunity aspects of electromagnetic compatibility for electrical and electronic apparatus intended for use on railway rolling stock.
This European Standard applies to emission and immunity aspects of electromagnetic compatibility for electrical and electronic apparatus intended for use on railway rolling stock.
The frequency range considered is from D.C. to 400 GHz. Testing is not defined for frequencies above 1 GHz.
This standard 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.
The emission and immunity limits in this Standard do not apply at the communication frequency, if a port is intended to transmit or receive for the purpose of radio communication.
The objective of this standard 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. The immunity requirements have been selected so as to ensure an adequate level of immunity for rolling stock apparatus.
