Schienen - Teil 4:Vignolschienen mit einer längenbezogenen Massezwischen 27 kg/m und unter 46 kg/mThis European Standard was approved by CEN on 9 January 2006.CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this EuropeanStandard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such nationalstandards may be obtained on application to the Central Secretariat or to any CEN member.This European Standard exists in three official versions (English, French, German). A version in any other language made by translationunder the responsibility of a CEN member into its own language and notified to the Central Secretariat has the same status as the officialversions.CEN members are the national standards bodies of Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France,Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania,Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.EUROPEAN COMMITTEE FOR STANDARDIZATIONCOMITÉ EUROPÉEN DE NORMALISATIONEUROPÄISCHES KOMITEE FÜR NORMUNGManagement Centre: rue de Stassart, 36

a See Table 3 for chemical composition/mechanical properties. b See Table 5 for hardness requirements. 6 Dimensions, static properties, linear mass and tolerances Rail profiles, dimensions, static properties and linear masses are given in Annex A. The tolerances of certain dimensions shall be as given in Table 6. All other quantities are informative only. NOTE Linear masses have been calculated based on the density of steel of 7,85 g/cm3. 7 Manufacture 7.1 Product integrity 7.1.1 Factory production control Rails shall be produced under a comprehensive system of factory production control, which shall ensure confidence in the conformity of the finished product. The system shall address this European Standard to ensure that the finished products consistently comply with requirements to achieve the product integrity necessary to provide assurance of product safety in track. Manufacturers shall demonstrate continuing compliance, including documented evidence, with the factory production control system required. Manufacturers having a factory production control system, which complies with EN ISO 9001 are recognised as satisfying the minimum requirements specified by this clause. 7.1.2 Best practice manufacture The product shall be manufactured to the best practices as defined in 7.1.1. NOTE This is to ensure that the rail attributes, described in the Introduction, which are not known in an exact manner or are not practically measurable, achieve the required high level of product integrity in track.

(40E1 profile rail rolled 1998, non-alloy rail steel grade R260) 7.4.2 Hot stamping In addition to the branding requirements of 7.4.1 each rail shall be identified by a numerical and/or alphabetical code system, hot stamped on the non-branded side of the rail web by machine and each rail shall be hot stamped at least once every 5 m. NOTE Subsequent cutting could result in more than one rail length having the same identity. The figures and letters used shall be clearly legible and shall be 16 mm high. The stamped characters shall have a flat or radius face (1 mm to 1,5 mm wide) with bevels on each side. The letters and numbers shall be on a 10° angle from vertical and shall have rounded corners. The stamping shall be between 0,5 mm and 1,5 mm in depth along the centre of the web. The design shall be as shown in Figure 1. The identification system employed shall be such as to enable the hot stamped marking to be collated with:
