Performance implies a certain quality level of the vehicle running gear, which every railway undertaking
28、 may require, notably by imposing procedures in approval and requesting the existence of a quality assurance system for the supply of rolling bearings intended for rolling stock operating on its network or other networks in Europe. BS EN 12080:2007+A1:2010EN 12080:2007+A1:2010 (E) 6 1 Scope This Eur
29、opean Standard specifies the quality parameters of axlebox rolling bearings, required for reliable operation of 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 conditi
