Up-to-date lists and bibliographical references concerning such nationalstandards may be obtained on application to the Management Centre 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 Management Centre has the same status as the officialversions.CEN members are the national standards bodies of Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece,Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and UnitedKingdom.EUROPEAN COMMITTEE FOR STANDARDIZATIONCOMITÉ EUROPÉEN DE NORMALISATIONEUROPÄISCHES KOMITEE FÜR NORMUNGManagement Centre: rue de Stassart, 36

The equipment specified is thatwhich gives the best probability of achieving the required product for use in track.
In the future new technology canadd to, but preferably will reduce or delete such items.Examples of areas where the technological state of the art renders the standard less than complete include: oxide/oxygen relationships; hydrogen test techniques; roller straightening effects on residual stresses; roller straightening effects on contact scrub; measurement and effect of residual stresses throughout the rail.SIST EN 13674-1:2004

106 cycles.NOTELife is defined as the complete separation of the specimen.8.5 Residual stress in rail foot8.5.1 Test methodThe residual stresses in the rail foot shall be determined in accordance with annex C.8.5.2 Test piecesEach of the 6 test pieces from the rail section shall be 1 m in length and shall be taken from rails as described in8.1.3 and 8.1.5.NOTEOnly a small part of the test piece will be destroyed for the purpose of measuring residual stress; the remaindercan be used for other qualifying approval tests.8.5.3 MeasurementsLongitudinal residual stress determinations shall be made on the rail foot of each of the 6 test pieces described in8.5.2. The location of the measurements is shown in Figure C.1.If data are available for straightness class A rails then class B rails of the same profile need not be tested.8.5.4 Qualifying criteriaThe maximum longitudinal residual stress in the foot shall be 250 MPa for all steel grades.8.6 Variation of centre line running surface hardness of heat treated railsThis clause only applies to heat treated rails.For the longest length of rail produced by the manufacturer, a one metre length of rail shall be taken from each endand at 20 m intervals from one end of the rail. These shall be hardness tested (HBW) in accordance withEN ISO 6506-1 along their length at 25 mm intervals on the centreline of the running surface after 0,5 mm hasbeen ground away. The hardness results shall be no more than
15 HBW from the mean result obtained.SIST EN 13674-1:2004
