This standard specifies limits and measuring methods for the emission and immunity of electrical and electronic apparatus that are foreseen to be installed in rolling stock. The requirements are valid for the frequency range 0 Hz to 400 GHz. Typical examples for the apparatus that are covered in this standard are listed in annex A. The specific requirements apply together with the EN 50121-1. In relation to the previous edition the undated references were changed into dated references the requirements for the emission were extended in the frequency range from 1 GHz to 6 GHz and for the immunity in the frequency range from 5,1 GHz to 6 GHz.
