Introduction This European Standard has been prepared in the form of a Product Stan
18、dard. It defines the immunity and emission test requirements for apparatus defined in the scope in relation to the electromagnetic disturbances likely to be experienced in the railway. In particular, the test requirements represent the essential electromagnetic immunity requirements and have been se
19、lected to ensure an adequate level of immunity for apparatus installed in the railway locations. Test requirements are specified for each port considered. Safety considerations are not covered by this standard. In special situations, where the level of disturbances may exceed the levels considered i
20、n this standard, e.g. at a special location or where a hand held transmitter is used in very close proximity to an apparatus, special mitigation measures may have to be employed. 1 Scope This European Standard applies to signalling and telecommunication apparatus which is installed in the railway en
21、vironment. Signalling and telecommunication apparatus mounted in vehicles is covered by EN 50121-3-2. This standard specifies limits for emission and immunity and provides performance criteria for signalling and telecommunications (S however, additional information needed for the practical applicati
22、on of the tests is given where appropriate. Voltages induced by traction currents are not treated here. They have to be covered by the functional specification. 7 EN 50121-4:2006 ?
