Railway applications - Rail - Part 1: Vignole railway rails 46 kg/m and above

This document specifies Vignole railway rails of 46 kg/m and greater linear mass, for conventional and high speed railway track usage.
Pearlitic steel grades are specified covering a hardness range of 200 HBW to 440 HBW and include non heat treated non alloy steels, non heat treated alloy steels, and heat treated non alloy steels and heat treated alloy steels.
There are 24 rail profiles specified in this document.
Two classes of rail straightness are specified, differing in requirements for straightness, surface flatness and crown profile. Two classes of profile tolerances are specified.

Bahnanwendungen - Schienen - Teil 1: Vignolschienen ab 46 kg/m

Dieses Dokument enthält Festlegungen für Vignolschienen mit einer längenbezogenen Masse ab 46 kg/m für konventionelle und Hochgeschwindigkeitsstrecken im Eisenbahnwesen.
Es sind perlitische Stahlsorten in einem Härtebereich zwischen 200 HBW und 440 HBW festgelegt. Die Schienen sind entweder nicht wärmebehandelt und bestehen aus unlegiertem Stahl bzw. legiertem Stahl oder sind wärmebehandelt und bestehen aus unlegiertem Stahl bzw. legiertem Stahl.
In dieser Norm sind 24 Schienenprofile festgelegt.
Zwei Geradheitsklassen sind festgelegt, die sich hinsichtlich der Anforderungen an die Geradheit, die Fahrflächenebenheit und das Kopfprofil unterscheiden. Für die Profiltoleranzen sind zwei Klassen festgelegt.

Applications ferroviaires - Rails - Partie 1 : Vignole de masse supérieure ou égale à 46 kg/m

Le présent document caractérise les rails ferroviaires Vignole symétriques de masse linéaire supérieure ou égale à 46 kg/m, destinés à l’usage des voies classiques et à grande vitesse.
Les nuances d'acier perlitique spécifiées sont dans une fourchette de dureté comprise entre 200 HBW et 440 HBW et incluent les aciers non traités thermiquement non alliés, les aciers alliés non traités thermiquement, les aciers traités thermiquement non alliés et les aciers traités thermiquement alliés.
24 profils de rail sont spécifiés dans le présent document.
Deux classes de rectitudes des rails sont spécifiées, différenciées par les exigences de rectitude, la planéité de la surface et le bombé du champignon. Deux classes de tolérances de profils sont également spécifiées.
