14、 11 3 EN 50121-4:2006 Introduction This European Standard has been prepared in the form of a Product Standard. 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 particu
15、lar, the test requirements represent the essential electromagnetic immunity requirements and have been selected 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
16、 this standard. In special situations, where the level of disturbances may exceed the levels considered in 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 Eur
