This document applies to hydraulic dampers (excluding end mountings) used on rail vehicles. The dampers covered in this standard include:
-- dampers that control the dynamic behaviour of vehicle:
- suspension dampers, (e.g. primary vertical dampers, secondary vertical dampers and secondary lateral dampers),
- yaw dampers,
- roll dampers,
- inter-vehicle dampers,
-- dampers that control the dynamic behaviour of mechanical systems:
- pantograph dampers,
- etc.
All relevant terminology which is specific to the subject is defined in this document.
