This European Standard shall be given the
23、 status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2004, and conflicting national standards shall be withdrawn at the latest by September 2004. This document has been prepared under a mandate given to CEN by the European Commissio
24、n and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this document According to the CEN/CENELEC Internal Regulations, the national standards organizations of th
25、e following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain,

27、tandards) 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 characteristics that had to be verified for the qualification were not given. This st
28、andard 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 procedures (see informative annex E); c) definition of the delivery conditions (see
29、 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 assurance concepts (see F.5). The standard defines the wheel product qualification
30、, 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 and ER9 are defined in this standard. Some characteristics are defined according
31、to a category 1 or a category 2. Category 1 is generally chosen when the train speed is higher than 200 km/h. These categories can sometimes be subdivided, depending upon the characteristics. This standard is applicable to solid forged and rolled wheels which are made from vacuum degassed steel and
32、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 to EN 13979-1 for their design. NOTE 1 The definition of other wheels may be found in other documents, such a
33、s UIC leaflets or ISO standards. NOTE 2 The technical approval procedure is not within the scope of this standard. NOTE 3 “Rim-chilled“ describes heat treatment of the rim, the aim of which is to harden the rim and to create compressive residual stresses in the rim. Licensed Copy: Wang Bin, ISO/Exch
