BS EN 12082:2017EN 12082:2017 (E) 5 Introduction To improve the reliability, availability, durability, the high speed capacity and maintenance
34、of the European rail transportation system, there is a need to ensure the required quality, safety and efficiency of axleboxes that are covered by the set of standards: EN 12080, EN 12081 and EN 12082. This European Standard has been drawn up with the purpose of standardizing the performance testing
35、 of axleboxes for all types of rolling stock to ensure suitability for the required service, i.e. that the assembly of box housing, bearing(s), seal(s) and grease is well suited for the service requirements. This testing is made in two stages, a “rig test”, described in detail in this European Stand
36、ard, and a “field test”. The extent of testing to be applied depends on the novelty of bearing design, seal design, grease formulation and/or box housing, as well as the application (see EN 12080 and EN 12081). BS EN 12082:2017EN 12082:2017 (E) 6 1 Scope This European Standard specifies the principl
37、es 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 v
38、ehicles 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”
39、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 rol
40、ling bearings and greases according to EN 12080 and EN 12081. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
