EN 12082:2017/FprA1

Railway applications - Axleboxes - Performance testing

This European Standard specifies the principles and methods for a rig performance test of the system of axlebox rolling bearing(s), housing, seal(s) and grease. 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 standard is historically developed for outboard applications but can be used for vehicles with other bearing arrangements (e.g.: inboard application or single wheels).
It gives some possible examples where a "sequenced performance test" addresses the broad range of different service conditions within a specific application or vehicle platform into account.
It describes in detail the water tightness test and basic principles and minimum requirements for a field test.
This European Standard only applies to axleboxes equipped with rolling bearings and greases according to EN 12080 and EN 12081.
