This standard specifies limits and measuring methods for the emission and immunity of all types of rolling stock (traction vehicles, trains and independent hauled stock). The requirements are valid for the frequency range 0 Hz to 400 GHz. The scope ends at the interface of the stock with its energy inputs and outputs. Furthermore this pre-standard does not apply to intentional communication signals. 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 a EMC plan. For the emission appropriate limits and the associated test procedures are specified. The specific requirements apply together with the EN 50121-1.
