Are you ready for the changes to EN 50121?

The new sections of EN 50121 which target apparatus (including rolling stock) are now listed in the Official Journal of the European Union.  

For the new parts of the standards, apparatus which has been tested to the 2006 version will cease to have a presumption of conformity from the 30th November 2018 – less than 4 months’ time – and will need assessment against the new version prior to updating its Declaration of Conformity.

Although the scope of the new parts of EN 50121 remains the same, there are a number of detailed technical requirements that may be different enough to raise questions for apparatus conforming to the previous 2006 versions.

Which parts of the standards are affected?

The Official Journal lists the new versions of the sections of standards, or whole standards where applicable, alongside the superseded standards.

As a quick reference, below is the information that is relevant to EN 50121:

Standard First Publication (OJ) Reference of superseded standard Date of cessation of presumption of conformity of superseded standard
EN 50121-3-1:2017 Railway applications — Electromagnetic compatibility — Part 3-1: Rolling stock — Train and complete vehicle This is the first publication EN 50121-3-1:2006

Fundamentals of EMC in Railways

This 5-day course delivers an in-depth study of EMC in the complex railway environment. It provides an understanding of its importance and the need to manage EMC from project concept to completion.

It is illegal to sell or operate electronic equipment or systems that are not compliant with the EMC Directive within the European Economic Area. In the rail environment, additional regulations are also laid down by companies such as Network Rail, Crossrail and London Underground.

Topics covered in this course help you to understand and manage the railway electromagnetic environment. The legal EMC requirements will be explained and how these are satisfied by use of standards and Technical Documentation; these requirements are related to safety and safety case requirements.
