This European Standard specifies the conformity assessment arrangements for newly manufactured EMS installed on a traction unit. This includes the integration conformity assessment and installation conformity assessment. In addition, this document also specifies the conformity assessment procedures for device and ancillary component replacement (e.g. due to damage in service), and periodic check to verify the EMSconformity assessment remains valid.

This European Standard does not include elements related to conformity assessment aspects other than design review and testing provisions for the products, processes or services specified. Consequently, this part does not delete, change or interpret the general requirements for conformity assessment procedures and vocabulary detailed in EN/ISO/IEC 17000.

This European Standard does not cover the conformity assessment schemes that, according to the CEN-CENELEC Internal Regulations, are the responsibility of ISO policy committee “Committee on conformity assessment” (ISO/CASCO).
