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.
