Bibliography

This European Standard applies to hydraulic dampers and their end mountings used on rail vehicles. The dampers covered in this standard include:-Dampers that control the dynamic behaviour of a vehicle:-Suspensions dampers, (e.g. primary vertical dampers, secondary vertical dampers and secondary lateral dampers);-Yaw dampers;-Roll dampers;-Inter-vehicles dampers.-Dampers that control the dynamic behaviour of mechanical systems:-Pantograph dampers;-Motor dampers, etc.All relevant terminology which is specific to the subject is defined in this European Standard.
