DIN EN 50121-3-1:2016-01

This standard contains the German version of the European Standard EN 50121-3-1:2015. It specifies limits and measurement methods for spurious emission and immunity for all types of railway vehicles (traction vehicles and trains as well as hauled stock). The requirements are valid for the frequency range 0 Hz to 400 GHz. The scope ends at the interface of the railway vehicle with its energy inputs and outputs. Intentional communication signals are excluded. No immunity tests apply to the complete vehicle provided that the rolling stock is immune against an appropriate disturbance level and that the assembly of the apparatus into a complete vehicle is implemented according to an EMC plan. For the spurious emission appropriate limits and the associated test procedures are specified. The specific provisions are to be used in conjunction with DIN EN 50121-1 (VDE 0115-121-1). Compared to the previous standard, the scope, definitions and applicability of the specifications have been clarified and the previously undated references have been changed to dated references. In addition, the specifications on the subject of influences on telecommunication lines outside the railway area have been clarified in 6.2. Finally, the limit values for radiated magnetic fields in the frequency range 9 kHz to 150 kHz have been deleted, since it was found that there are only a few susceptible devices outside the railroad area, the interference radiation values measured in 10 m are not representative with respect to the compatibility of equipment within the railway area, the intra-EMC in this frequency range is covered by other methods and standards, and the reproducibility of the measurement method is low. Finally, Annex A has been clarified with regard to psophometric currents and an example of a national regulation has been included (Annex C). The responsible committee is DKE/UK 767.12 "Funkstörungen durch Hochspannungsfreileitungen und -anlagen und EMV von Bahnen" ("Radio interference by high voltage overhead lines and installations and EMC of railways") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
