(Main)Railway applications - Infrastructure - Flash butt welding of rails - Part 3: Welding in association with crossing construction
Railway applications - Infrastructure - Flash butt welding of rails - Part 3: Welding in association with crossing construction
This document specifies requirements for the approval of a welding process in a fixed plant, together with the requirements for subsequent welding production.
This document applies to new Vignole rails manufactured in accordance to EN 13674-1 and welded by flash butt welding to crossing components in a fixed plant, and intended for use on railway infrastructures.
This document applies to cast Manganese crossings manufactured to EN 15689, fabricated crossings manufactured from rail and crossings manufactured from forged/rolled premium steels.
NOTE EN 14587-1 is also used for the flashed butt welding of switches.
Sometimes special profiles exist in crossing construction, which are not rail profiles as defined in EN 13674 series (example: profile with machined off rail foot). In these cases, tests are defined by the railway authority in participation with the manufacturer.
Bahnanwendungen - Infrastruktur - Abbrennstumpfschweißen von Schienen – Teil 3: Schweißen im Zusammenhang mit Herzstückkonstruktionen
Diese Europäische Norm legt die Anforderungen für die Zulassung eines Schweißverfahrens in einem Schweißwerk fest, gemeinsam mit den Anforderungen für die spätere Schweißung.
Diese Europäische Norm ist anwendbar für neue, nach EN 13674-1 hergestellte Vignol-Schienen mit in einer stationären Anlage abbrennstumpfgeschweißten Herzstückkomponenten, die für den Einsatz in der Eisenbahn-Infrastruktur vorgesehen sind.
Diese Norm gilt für nach EN 15689 hergestellte Manganguss-Herzstücke sowie für aus Schienen und aus geschmiedeten und gewälzten Edelstählen hergestellte Herzstücke.
ANMERKUNG EN 14587-1 ist auch zum Abbrennstumpfschweißen von Weichen zu verwenden.
In Kreuzungskonstruktionen können Sonderprofile vorliegen, die keine Schienenprofile nach den Definitionen in der Normenreihe EN 13674 sind (Beispiel: Profile mit maschinell bearbeitetem, außerhalb der Schiene liegendem Fuß). In solchen Fällen dürfen die Eisenbahnunternehmen zusammen mit dem Hersteller die Prüfungen vorgeben.
Applications ferroviaires - Voie - Soudage des rails par étincelage - Partie 3 : Soudure en association avec la construction des appareils de voie
Le présent document spécifie les exigences pour l'homologation d'un procédé de soudage dans une installation fixe, ainsi que les exigences pour les soudures de production.
Le présent document s’applique aux rails Vignole neufs fabriqués conformément à l’EN 13674 1 soudés par étincelage à des composants d’appareil de voie dans une installation fixe et destinés à des infrastructures ferroviaires.
Le présent document s'applique aux cœurs de voie en manganèse coulé fabriqués conformément à l’EN15689, aux cœurs fabriqués à partir de rails et aux cœurs fabriqués à partir d'aciers premium forgés/laminés.
NOTE L’EN 14587 1 est également utilisée pour le soudage par étincelage des interrupteurs.
Dans la construction de cœurs de voie, on peut trouver des profils spéciaux qui ne sont pas des profils de rail tels que définis dans la série de normes EN 13674 (exemple : profil avec patin usiné). Dans ces cas, les essais sont définis par l'autorité ferroviaire en collaboration avec le fabricant.
