20、13298:2003 (E) Foreword This document (EN 13298:2003) has been prepared by Technical Committee CEN/TC 256 “Railway Applications“ the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsem
21、ent, at the latest by September 2003, and conflicting national standards shall be withdrawn at the latest by September 2003. In this European Standard the annexes A to E are normative. The preparation of this European Standard started in early 1992 with the aim to integrate the existing documents su
22、ch as UIC 822 (International Union of Railways) and internal documents of various railway companies into a concise standard. According to the CENKENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgi
23、um, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and the United Kingdom. 4 EN 13298:2003 (E) 1 Scope This European Standard is applicable to helical steel suspension
24、 springs used in the suspension of rail vehicles. It deals specially with cylindrical compression springs made from round section steel bars of constant diameter and with constant inclination of coiling. It deals also with helical springs with different shapes (e.g. conical and/or inclination of coi
25、ling not constant and/or steel bar with other cross sections, etc.). This standard gives guidance for: - design; - specification of technical and quality requirements; - the approval procedure and quality assurance of production methods; - the examinations and tests to be carried out; - the delivery
26、 conditions. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendment
27、s to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.
