This European Standard specifies the quality parameters of axlebox rolling bearings supporting the load of the vehicle, required for reliable operation of trains on European networks. It covers metallurgical and material properties as well as geometric and dimensional characteristics. It also defines methods for quality assurance and conditions for approval of the products.

This document defines the interfaces and gives guidance for the design of systems and procedures for change of track gauge. It defines also their assessment for technical approval, for the automatic variable-gauge systems. The document is focused on the change of track gauge among the following nominal track gauges: 1 435 mm, 1 520 mm, 1 524 mm, 1 600 mm and 1 668 mm. This document is not limited to the aforementioned nominal track gauges but the interfaces to change to/from other nominal track gauges can be different. The established assessment procedures can be used as well.

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.

This document specifies the principles and methods for deployment of the system of axlebox rolling bearing(s), housing, seal(s) and grease, required for reliable operation of trains on European networks. It covers the conformity assessment with respect to design requirements on the rolling bearing(s) according EN 12080 and grease according EN12081 as well as the performance of (rig) tests according to EN 12082 1 . This document is historically developed for outboard applications with rotating inner rings, but can be used for vehicles with inboard bearing arrangements with rotation inner rings. The present document describes the complete deployment procedure for new axleboxes. For certain cases and based on a documented risk assessment, a reduced deployment procedure is described. This document only applies to axleboxes equipped with rolling bearings and greases according to EN 12080 and EN 12081. It is not within the scope of EN 12082 2 to define the validation procedure of box housings, sleeves or coves from a structural point of view. The relevance of these parts in the scope of this document is limited to the interaction with the axle box rolling bearing with respect to the required service.

This docuemnt specifies the principles and methods for a rig performance test of the system of axlebox rolling bearing(s), housing, seal(s) and grease, required for reliable operation of trains on European networks. It covers a rig performance test, a water tightness test and basic principles for a field test. Test parameters and minimum performance requirements for vehicles in operation on main lines are specified. Different test parameters and performance requirements may be selected for vehicles in operation on other networks (e.g. urban rail). This document is historically developed for outboard applications with rotating inner rings, but can be used for vehicles with inboard bearing arrangements. It gives some possible examples where a sequenced rig performance test addresses the broad range of different service conditions within a specific application or vehicle platform into account. It describes compatibility tests of components for their integration into the axlebox system. With respect to design requirements on the rolling bearing(s) according EN 12080 and grease according EN 12081, it outlines requirements for the deployment of the respective component or assembly . This documetn only applies to axleboxes equipped with rolling bearings and greases according to EN 12080 and EN 12081.
