BS EN 12081:2007+A1:2010EN 12081:2007+A1:2010 (E) 4 Introduction This European Standard has been drawn up with the purpose to define the minimum requirements of greases used for the lubrication of rolling bearings in railway axleboxes. The purpose is to ensure a certain performance lev
24、el in the interest of operating safety in international traffic. Performance implies a certain quality level of the vehicle running gear, which every railway undertaking may require, notably by imposing procedures in approval and quality assurance for the supply of axleboxes. Lubricating greases int
25、ended for use in axlebox bearing application need to fulfil the requirements of this European Standard, complying with Table A.1. Additional requirements for high speed or specific bearing types, environment or operating conditions are detailed in Table B.1. This specification has been written so th
26、at it reflects the typical performance of e.g. a NLGI grade 2 simple lithium soap grease, based on a mineral oil with a base oil viscosity of 100 mm2/s at 40 C such as would be found in current use. However, this specification needs to not restrict or limit grease evolution for more demanding applic
27、ations of today and in the future, hence several parameters are left open for agreement. For example, the base oil viscosity can be reduced for high speed applications, and where sealed bearing units are being used the grease grade may need to be lower.

28、(E) 5 1 Scope This European Standard specifies the quality requirements of greases intended for the lubrication of axlebox rolling bearings according to EN 12080, required for reliable operation of trains on European networks. It covers the approval procedure, the method of quality control and quali
29、ty monitoring of the grease. The grease requirements are given for two speed classes. 2 Normative references The following referenced documents are indispensable for the application of this document.
