Executive summary

Emission and immunity levels of electromagnetic interference in signalling and telecommunication apparatus.

Abstract

This European Standard applies to signalling and telecommunication apparatus which is installed in the railway environment.

It specifies limits for emission and immunity and provides performance criteria for signalling and telecommunications (S&T) apparatus which may interfere with other apparatus in the railway environment, or increase the total emissions for the railway environment beyond the limits defined in the appropriate standard, and so risk causing Electro-Magnetic Interference (EMI) to apparatus outside the railway system.

Apparatus which conforms to the emission levels of EN 50081-2, will meet the emission requirements of this standard. The immunity levels given for the apparatus will in most cases allow the apparatus to perform as intended in the railway environment.

This standard does not specify basic personal safety requirements for apparatus such as protection against electric shock, unsafe operation, insulation co-ordination and related dielectric tests. The requirements were developed for and are applicable to this set of apparatus when operating under normal conditions. The requirements and test methods also apply to S&T data and power lines connected to the equipment under test (EUT).

The frequency limits for emission and immunity requirements are from D.C. to 400 GHz. At present testing is not defined for frequencies below 150 kHz (except for traction fundamental frequencies) and above 1 GHz because of difficulties in specifying appropriate test methods.
