Railway applications - Track - Aluminothermic welding of rails - Part 1: Approval of welding processes

This standard defines the laboratory tests and requirements for approval of an aluminothermic welding process using welds produced in workshop conditions.
It applies to the joining of new, Vignole rails as described in EN 13674-1 of the same profile and steel grade.
Compliance with the requirements of this standard does not of itself ensure the suitability of a welding process for specific conditions of track and traffic.
The standard does not cover welds made between different rail sections, differently worn rails and different rail grades.
In addition to the definitive requirements this standard also requires the items detailed in Clause 4 to be documented. For compliance with this standard, it is important that both the definitive requirements and the documented items be satisfied.

Bahnanwendungen - Oberbau - Aluminothermisches Schweißen von Schienen - Teil 1: Zulassung der Schweißverfahren

Diese Norm definiert Laborprüfungen und Anforderungen zur Zulassung eines aluminothermischen Schweißverfahrens an unter Werkstattbedingungen hergestellten Schweißungen.
Diese Norm umfasst die Verbindung von Vignolschienen, wie in EN 13674-1 beschrieben, des gleichen Profils und gleicher Stahlsorte.
Die Erfüllung der Anforderungen dieser Norm bedingt jedoch nicht notwendigerweise die Eignung des Schweißprozesses für spezifische Bedingungen im Oberbau und im Betrieb.
Die Norm berücksichtigt nicht die Schweißungen von unterschiedlichen Schienen-Querschnitten, unterschiedlich abgenutzten Schienen und unterschiedlichen Stahlsorten.
Zusätzlich zu den in dieser Norm definierten Anforderungen sind auch die in Abschnitt 4 beschriebenen Forderungen zu dokumentieren. Für die Übereinstimmung mit dieser Norm sind sowohl die definierten Anforderungen als auch die zu dokumentierenden Dinge zu erfüllen.

Applications ferroviaires - Voie - Soudage des rails par aluminothermie - Partie 1 : Approbation des procédés de soudage

La présente norme définit ces essais de laboratoire et les exigences pour l’approbation d’un procédé de soudage des rails par aluminothermie.
Elle s’applique à l’assemblage de rails Vignole neufs tels que décrits dans l'EN 13674-1, de même profil et de même nuance d’acier.
La conformité aux exigences de la présente norme n’assure pas par elle-même l’aptitude à l’emploi d’un procédé de soudage dans des conditions spécifiques de voie ferrée et de trafic.
La présente norme ne s'applique pas au soudage des rails de profils, d'usures ou de nuances différentes.
Outre les exigences définitives, la présente Norme exige également que les éléments détaillés à l’Article 4 soient documentés. Pour être conforme à la présente norme, il est important que les exigences définitives ainsi que les éléments à documenter soient remplis.

Železniške naprave - Zgornji ustroj - Aluminotermično varjenje tirnic - 1. del: Odobritev varilnega postopka

Ta standard opredeljuje laboratorijske preskuse in zahteve za odobritev aluminotermičnega varilnega postopka z uporabo zvarov, narejenih v pogojih delavnice. Velja za spajanje novih Vignolovih tirnic, kot opisuje 13674-1, z istim profilom in vrsto jekla. Skladnost z zahtevami tega standarda sama po sebi ne zagotavlja primernosti varilnega postopka za določene pogoje zgornjega ustroja in prometa. Standard ne zajema zvarov, narejenih med različnimi deli tirnic, različno obrabljenimi tirnicami in različnimi vrstami tirnic. Poleg končnih zahtev ta standard prav tako zahteva, da so postavke, navedene v Klavzule 4, dokumentirane. Za skladnost s tem standardom je pomembno, da so izpolnjene končne zahteve in dokumentirane postavke.
