37、rs 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
38、of mechanical systems: pantograph dampers; motor dampers, etc. All relevant terminology which is specific to the subject is defined in this European Standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for it
