Common safety method for conformity assessment (safety certificates)


This page gives an overview of the common safety method (CSM) for conformity assessment (safety certificates), which has been adopted and published by the European Commission.

Common safety methods are developed by the European Commission and the European Union Agency for Railways (ERA) to support the single market in the rail sector.

European Commission Regulation (EU) 1158/2010 (the CSM for conformity assessment of safety certificates) came into force on 3 January 2011. It provides a common approach across the EU for the assessment of applications for safety certificates by national safety authorities.

ORR has published an assessment criteria document for applications for a mainline safety certificate which contains the provisions of the CSM.
