Element provides testing and certification services to ensure the safety and reliability of railway components and systems. We can help you meet the EN 50121 standards for electromagnetic compatibility (EMC).


What is EN 50121

The five standards provide a framework for managing the EMC for railways. It specifies the limits for the electromagnetic (EM) emission of the railway as a whole to the outside world and for the EM emission and immunity for equipment operating within the railway.


Limits and levels are chosen to ensure a reasonable level of EMC with other apparatus within the local railway environment. 


Supporting you in meeting Railway standards

  • EN 50121-3-2 - EMC emission and immunity testing of Rolling Stock Apparatus 
  • EN 50121-4 - EMC emission and immunity testing of signaling and telecommunications apparatus
  • EN 50121-5 - EMC Emission and immunity testing of fixed power supply installations and apparatus
  • EN 50121-3-1 - EMC emissions testing of Rolling Stock, Train, and Complete Vehicle
  • EN 50121-2 - EMC emissions testing of the whole railway system to the outside world
  • EN 50155 - EMC and environmental testing of Rolling stock and Electronic equipment
