26、 been drawn up with the purpose of aiming at optimum performance in rail transportation. Performance implies a certain quality level of the vehicle running gear, which every railway company may require, notably by imposing procedures in approval and requesting the existence of a quality assurance sy
27、stem for the supply of rolling bearings intended for rolling stock operating on its network or other networks in Europe. 1 Scope This European Standard defines the quality parameters of axlebox rolling bearings, required for reliable operation of trains on European networks. It covers metallurgical
28、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 This European Standard incorporates, by dated or undated reference, provisions from other publications. Thes
29、e normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated r
