UIC 518

Testing and Approval of Railway Vehicle Running Behaviour

UIC 518 is the International Union of Railways standard that specifies dynamic testing requirements for acceptance of railway vehicles based on running behaviour criteria. This standard, which served as the basis for the later EN 14363, defines measurements and limits for vehicle response to track irregularities, lateral dynamics, and operational safety across varying track conditions. It is historically significant in European rail certification and remains in use for certain vehicle classes and retrofit assessments. Accreditation for UIC 518 testing ensures proper measurement methodology and comparison against established international railway acceptance criteria.

What it measures

  • Lateral acceleration response
  • Wheel load variation under dynamic conditions
  • Vehicle body acceleration and displacement
  • Derailment coefficient assessment
  • Running safety indices
