Abstract

This Final Draft International Standard is an up to 6 weeks' pre-release of the official publication. It is available for sale during its voting period: 2017-11-24 to 2018-01-05. By purchasing this FDIS now, you will automatically receive, in addition, the final publication.

This third edition cancels and replaces the second edition published in 2008. It constitutes a technical revision and has been developed on the basis of EN 50121-2:2017. This edition includes the following significant technical changes with respect to the previous edition: 
a) clarification of scope (Clause 1); 
b) combination of former Clause 5 and Annex A related to method of measurement for moving trains and traction substations (5.1); 
c) moving emission values for radiated H-fields in the frequency range 9 kHz to 150 kHz to new Annex C due to the fact that: 
– there are very few outside world victims;
– there is low reproducibility. 
d) clarification of acquisition method (5.2).
