This Part 1 of the European standards series EN 50121 outlines the structure and the content of
the whole set. This part alone is not sufficient to give presumption of conformity to the essential
requirements of the EMC-Directive and must be used in conjunction with other parts of this standard.
Annex A describes the characteristics of the railway system which affect electromagnetic compatibility
(EMC) behaviour.
Phenomena excluded from the set are Nuclear EM pulse, abnormal operating conditions and the
induction effects of direct lightning strike.
Emission limits at the railway boundary do not apply to intentional transmitters within the railway
boundaries.
Safety considerations are not covered by this set of standards.
The biological effects of non-ionising radiation as well as apparatus for medical assistance, such as
pacemakers, are not considered here.
