Scope

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.
