DIN EN 13262:2011-06 EN 13262:2004+A2:2011 (E) 5 Introduction Normative documents which have
26、been used until now in Europe for the wheel delivery (UIC leaflets, national standards) had for the main purpose, a complete definition of the delivery procedures and the wheel characteristics that were to be measured. Product qualification was sometimes mentioned, but the procedures and the charact
27、eristics that had to be verified for the qualification were not given. This standard addresses these requirements by: a) definition of all the wheel characteristics. These are either verified during the qualification or delivery of the product (see clause 3); b) definition of the qualification proce
28、dures (see informative annex E); c) definition of the delivery conditions (see informative annex F). Here, a choice is given to the supplier of either: - a traditional delivery procedure with a control by batch sampling as in existing documents (see F.4), or - a delivery procedure using quality assu
29、rance concepts (see F.5). The standard defines the wheel product qualification, the technical approval procedure is not within the scope of this standard. 1 Scope This European Standard specifies the characteristics of railway wheels for use on European networks. !Four steel grades, ER6, ER7, ER8 an
30、d ER9 are defined in this standard; for European freight wagon interoperability purposes only grades ER6, ER7 and ER8 are applicable. NOTE 1 Grade ER6 is not normally fit for the duty of application to freight wagons; it is normally applied in low axleload situations.“ !Certain characteristics are d
31、efined according to a category 1 or a category 2. Category 1 is generally chosen when the train speed is higher than 200 km/h. Freight vehicles running at speeds lower than 200 km/h generally use wheels of Category 2.“ These categories can sometimes be subdivided, depending upon the characteristics.
32、 This standard is applicable to solid forged and rolled wheels which are made from vacuum degassed steel and have a chilled rim. They are to have already been used in commercial conditions on a European network in a significant quantity, or to have satisfied a technical approval procedure according
33、to EN 13979-1 for their design. !NOTE 2“ The definition of other wheels may be found in other documents, such as UIC leaflets or ISO standards. !NOTE 3“ The technical approval procedure is not within the scope of this standard. !NOTE 4“ Rim-chilled“ describes heat treatment of the rim, the aim of wh
34、ich is to harden the rim and to create compressive residual stresses in the rim.
