8、ive elements, as defined in Clause 3 of the CEN/CENELEC Internal Regulations, Part 3.Normative: Requirements conveying criteria to be fulfilled if compliance with the document is to be claimed and from which no deviation is permitted.Informative: Information intended to assist the understanding or u
9、se of the document. Informative annexes do not contain requirements, except as optional requirements, and are not mandatory. For example, a test method may contain requirements, but there is no need to comply with these requirements to claim compliance with the standard.When speeds in km/h require u
10、nit conversion for use in the UK, users are advised to use equivalent values rounded to the nearest whole number. The use of absolute values for converted units should be avoided in these cases. In the following standard, 200 km/h should be taken as equivalent to 125 mph.The UK participation in its

BS EN 12080:2017EN 12080:2017 (E) 6 Introduction This standard is part of a set of standards: EN 12080, EN 12081 and EN 12082. This European Standard has been drawn up with th
39、e purpose of aiming at optimum performance in rail transportation. Performance implies a certain quality level of the vehicle running gear, which every railway undertaking may require, notably by imposing procedures in approval and requesting the existence of a quality assurance system for the suppl
40、y of rolling bearings intended for rolling stock operating on its network or other networks in Europe. BS EN 12080:2017EN 12080:2017 (E) 7 1 Scope This European Standard specifies the quality parameters of axlebox rolling bearings supporting the load of the vehicle, required for reliable operation o
41、f trains on European networks. It covers metallurgical and material properties as well as geometric and dimensional characteristics. It also defines methods for quality assurance and conditions for approval of the products. 2 Normative references The following documents, in whole or in part, are nor
