(Main)Railway applications - Infrastructure - Mechanical requirements for joints in running rails
Railway applications - Infrastructure - Mechanical requirements for joints in running rails
This European Standard deals with mechanical rail joints for flat bottom rails 46 kg/m and over. The scope of this standard is: to
establish requirements for insulated and non-insulated rail joints, for stressed rail (continuous welded rail, CWR) and unstressed rail (jointed track); to define mechanical and electrical requirements for type approval and for acceptance of insulated rail joints which are manufactured in a factory (prefab construction) as well as assembled onsite (site construction). This standard specifies the minimum requirements. Special applications as for instance tram systems may require different demands in certain paragraphs and should be agreed between customer and supplier. The scope also excludes expansion joints (it is covered in EN 13232-8), and special joints in switch constructions.
Bahnanwendungen - Infrastruktur - Mechanische Anforderungen an Fahrschienenstöße
Dieses Dokument behandelt mechanische Schienenstöße für den dauerhaften Einbau an Vignolschienen von 46 kg/m und mehr.
Anwendungsbereich dieses Dokumentes:
Festlegung der Anforderungen für isolierte und nicht-isolierte Laschen der Schienenstöße, vorbelastete Schienen (zusammengeschweißte Langschiene (CWR, en: continuous welded rail)) und entspannte Schienen (verbundene Schienen);
Definition der mechanischen und elektrischen Anforderungen an die Bauartzulassung und Abnahme isolierter Schienenstöße, die in einem Werk hergestellt (vorgefertigt) und vor Ort montiert werden (Baustelle).
Dieses Dokument legt die Mindestanforderungen fest. Spezielle Anwendungen wie etwa für Straßenbahnsysteme können unterschiedliche Anforderungen in bestimmten Absätzen erfordern und werden zwischen dem Kunden und dem Lieferanten vereinbart.
Dieses Dokument ist anwendbar für Schienenverbindungen, die aus einem Schienenpaar mit rechtwinkligen oder abgewinkelten Schienenenden bestehen.
Der Anwendungsbereich dieses Dokumentes schließt alle Arten von temporären mechanischen Stößen in Gleisen aus wie beispielsweise während des Gleisbaus oder zur Sicherung gebrochener Schienen und Schweißverbindungen bis zur endgültigen Instandsetzung. Darüber hinaus schließt der Anwendungsbereich Auszugsvorrichtungen (behandelt in EN 13232 8) und Spezialstöße in Weichenkonstruktionen aus.
Applications ferroviaires - Infrastructure - Exigences mécaniques des joints dans les rails de roulement
Le présent document traite des joints mécaniques à usage permanent pour rails Vignole de masse supérieure ou égale à 46 kg/m.
Le domaine d'application du présent document est le suivant :
- établir les exigences relatives aux joints isolés et non isolés, pour les rails soumis à des contraintes de traction (voie en longs rails soudés, LRS) et les rails non soumis à des contraintes de traction (voie en rails éclissés) ;
- définir les exigences mécaniques et électriques relatives à l'homologation et à la réception des joints isolés fabriqués en usine (construction préfabriquée) et installés sur le terrain (construction sur site).
Le présent document définit les exigences minimales. Les applications spéciales, telles que les systèmes de tramway par exemple, peuvent exiger des demandes différentes dans certains paragraphes et il convient qu'elles fassent l'objet d'un accord entre le client et le fournisseur.
Le domaine d'application du présent document exclut tous les types de joints mécaniques destinés à être utilisés provisoirement en voie, par exemple pour la construction de voie ou la sécurisation des soudures et rails cassés avant réparation finale. Le domaine d'application exclut également les appareils de dilatation (voir EN 13232 8), ainsi que les joints spéciaux dans les constructions d'aiguillages.
Železniške naprave - Infrastruktura - Mehanske zahteve za spoje v voznih tirnicah
Ta evropski standard obravnava mehanske tirne spoje za tire z ravnim dnom 46 kg/m ali več. Področje uporabe tega standarda je:
določiti zahteve za izolirane in neizolirane tirne spoje, za napete tire (neprekinjeno zvarjene tirnice, CWR) in nenapete tire (stikovani tir); opredeliti mehanske in električne zahteve za homologacijo in potrditev izoliranih tirnih spojev, ki so izdelani v tovarni (montažna izdelava), in tistih, sestavljenih na kraju samem (izdelava na kraju samem). Ta standard določa minimalna zahteve. Za posebne načine uporabe kot na primer za sisteme tramvajev je morda treba uporabiti drugačne zahteve v določenih odstavkih; o tem naj se dogovorita odjemalec in dobavitelj. Področje uporabe vključuje tudi ekspanzijske spoje (zajete v standardu EN 13232-8) in posebne spoje v konstrukcijah kretnic.
