European foreword This document (EN 12081:2017) has been prepared by Technical Committee CEN/TC 256 “Railway Applications”, the secretariat of which is held by DIN. 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of an identical text or by endorsement, at the latest by March 2018, and conflicting national standards shall be withdrawn at the latest by March 2018.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. This 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: revised for quality batch control and traceability; — Clause 10: revised pack marking; — Clause 11: revised storage prescriptions; — Annex A: revised topic, now Approval Procedure; — Annex B: Revised topic, now contains requirements for initial grease approval and quality batch control in Table B.1; — Annex C (informative): added. This document has been prepared under a mandate given to CEN/CENELEC/ETSI by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive 2008/57/EC.

SIST EN 12081:2017
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 level 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 intended for use in axlebox bearing application need to fulfil the requirements 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 current 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. SIST EN 12081:2017
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 for a not-yet-approved grease, the management of modification for an approved grease and the method of quality batch 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.
