This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by March 2018,
24、 and conflicting national standards shall be withdrawn at the latest by March 2018. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. Th
25、is document supersedes EN 12081:2007+A1 2010. The main changes compared to the previous edition are the following: Clause 1: revised scope of the standard; Clause 2: revised and updated normative references; Clause 4: added REACH legislation; Clause 8: new definition of speed classes; Clause 9: revi

30、troduction 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 level in the interest of operating safety in international traffic. Per
31、formance 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 intended for use in axlebox bearing application need to fulfil the requ
32、irements of this European Standard, complying with Table B.1. This European Standard has been written so that it reflects the typical performance of, e.g. an 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 curre
33、nt use. However, this European Standard does not restrict or limit grease evolution for more demanding applications of today and in the future, hence several parameters are left open for agreement. BS EN 12081:2017EN 12081:2017 (E) 5 1 Scope This European Standard specifies the quality requirements
34、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 for a not-yet-approved grease, the management of modification for an approved grease and the method of quality b
35、atch control of the grease. The grease requirements are given for two speed classes. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
