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 noninsulated 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 132328), and special joints in switch constructions.

Bahnanwendungen - Infrastruktur - Mechanische Anforderungen an Fahrschienenstöße

Diese Europäische Norm behandelt mechanische Schienenstöße für Vignolschienen ab 46 kg/m.
Diese Norm hat folgenden Anwendungsbereich:
-   Festlegung der Anforderungen an Isolierstöße und unisolierte Schienenstöße von belasteten Schienen (durchgehend verschweißte Schienen (CWR)) und unbelasteten Schienen (verschraubte Schienen);
-   Festlegung der mechanischen und elektrischen Anforderungen an die Typprüfung und Annahme von Isolierstößen, die in einem Werk hergestellt werden (vorgefertigte Herstellung) und von Isolierstößen, die vor Ort zusammengebaut werden (Vor-Ort-Herstellung).
Diese Norm legt die Mindestanforderungen fest. Für besondere Anwendungen, wie z. B. Straßenbahnsysteme, können bezüglich bestimmter Abschnitte andere Anforderungen gelten, die zwischen Verbraucher und Lieferant zu vereinbaren sind.
Vom Anwendungsbereich ausgenommen sind auch Auszugsvorichtungen (die in EN 13232-8 behandelt werden) und besondere Stöße in Weichenkonstruktionen.

Applications ferroviaires - Infrastructures - Exigences mécaniques des joints dans les rails de roulement

La présente Norme européenne traite des joints mécaniques pour rails Vignole de masse supérieure ou égale à 46 kg/m.
Le domaine d’application de la présente Norme est le suivant :
-   établir les exigences relatives aux joints isolés et non isolés, pour les rails avec contraintes (longs rails soudés, LRS) et les rails sans contraintes (voie avec joints) ;
-   définir les exigences mécaniques et électriques relatives à l’homologation et à l’acceptation des joints isolés fabriqués en usine (construction préfabriquée) et installés sur le chantier (construction sur site).
La présente norme définit les exigences minimales. Les applications spéciales telles, par exemple, que les systèmes de tramway peuvent exiger des demandes différentes dans certains paragraphes et doivent être convenues entre le client et le fournisseur.
Le domaine d’application exclut également les joints de dilatation (ce point est couvert par l’EN 13232-8), ainsi que les joints spéciaux dans les constructions d’aiguillages.

This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee
CEN/TC 256.
If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations
which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,
Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and
United Kingdom.
Recipients of this draft are invited to submit, with their comments, notification of any relevant patent rights of which they are
aware and to provide supporting documentation.
