Railway applications - Braking systems of high speed trains - Part 2: Test methods

This European Standard specifies test methods and acceptance criteria for a brake system for use in high speed trains as described in the TSI Rolling Stock, operating on routes of the trans-European high-speed rail system.
The tests defined in this document have the purpose of verifying that the braking performance and functions of the train's brake system comply at least with the respective requirements of EN 15734-1.
This European Standard is applicable to:
-   new vehicles of high speed trains;
-   new constructions of existing vehicle types;
-   major overhauls of the above-mentioned vehicles if they involve redesigning or extensive alteration to the brake system of the vehicle concerned.
The functional testing requirements set out in this document assume the vehicles are fitted with a brake system architecture that follows the UIC air brake pipe control principles.
High Speed Rolling Stock can be fitted with alternative brake system architectures that do not employ brake pipe control. In these cases equivalent testing requirements will need to be generated to test the functional performance of brake system fitted.

Bahnanwendungen - Bremssysteme für Hochgeschwindigkeitszüge - Teil 2: Prüfverfahren

Diese Europäische Norm legt die Prüfverfahren und Zulassungsbedingungen eines Bremssystems für den Einsatz in Hochgeschwindigkeitszügen fest, wie sie in der TSI Hochgeschwindigkeitsfahrzeuge beschrieben sind und welche auf Strecken des Transeuropäischen Hochgeschwindigkeitsnetzes betrieben werden.
Die in dieser Norm definierten Prüfungen haben den Zweck festzustellen, dass die Leistung und Funktion des Zugbremssystems mindestens die entsprechenden Anforderungen nach EN 15734 1 erfüllt.
Diese Europäische Norm ist anzuwenden für:
—   alle neuen Fahrzeugbauarten von Hochgeschwindigkeitszügen;
—   alle Nachbauten bereits bestehender Fahrzeugbaureihen;
—   alle größeren Grundüberholungen der o. g. Fahrzeuge, wenn dies Neukonstruktionen oder umfassende Änderungen der Bremsanlage des betreffenden Fahrzeuges mit einschließt.
Die im vorliegenden Dokument enthaltenen funktionalen Prüfanforderungen gehen von der Annahme aus, dass die Architektur des Bremssystems der Fahrzeuge dem der UIC-Druckluftbremse entspricht.
Hochgeschwindigkeitsschienenfahrzeuge können mit einem alternativen Bremssystem ausgerüstet werden, welches nicht über eine Hauptluftleitung angesteuert wird. In diesen Fällen ist die Festlegung gleichwertiger Prüfanforderungen erforderlich, um die funktionalen Anforderungen des eingebauten Bremssystems zu prüfen.

Applications ferroviaires - Systèmes de freinage pour trains à grande vitesse - Partie 2 : Méthodes d'essai

La présente Norme européenne décrit les méthodes d’essai ainsi que les critères d’acceptation relatifs à un
système de freinage destiné à être utilisé sur des trains à grande vitesse décrits dans les spécifications
techniques d'interopérabilité (STI) Matériel roulant à grande vitesse, circulant sur des lignes du système
ferroviaire transeuropéen à grande vitesse.
Les essais définis dans le présent document ont pour objet de s’assurer que les performances de freinage et
les fonctions assurées par le système de freinage du train sont au moins conformes aux exigences
respectives de l’EN 15734-1.
La présente Norme européenne est applicable aux :
- véhicules neufs des trains à grande vitesse ;
- nouvelles constructions en ce qui concerne les types de véhicules existants ;
- grandes révisions des véhicules susmentionnés si celles-ci entraînent une reconception ou une
transformation majeure du système de freinage du véhicule concerné.
Les exigences d’essai fonctionnel définies dans le présent document supposent que les véhicules sont
équipés d’une architecture du système de freinage conforme aux principes UIC de commande par la conduite
générale de frein.
Le matériel roulant à grande vitesse peut être équipé d’autres architectures de système de freinage n’utilisant
par de commande par la conduite générale de frein. Dans ces cas, des exigences d’essai équivalentes
doivent être établies pour soumettre à essai les performances fonctionnelles du système de freinage installé.

Železniške naprave - Zavorni sistemi na vlakih z velikimi hitrostmi - 2. del: Preskusne metode

Ta evropski standard določa preskusne metode in kriterije sprejemljivosti za delovanje zavornega sistema za uporabo pri vlakih z velikimi hitrostmi, kot je opisano v tehničnih specifikacijah za interoperabilnost hitrih vlakov, ki vozijo po vseevropskem železniškem sistemu za velike hitrosti.
Namen preskusov, opredeljenih v tem dokumentu, je preveriti, ali zavorna zmogljivost in funkcije zavornega sistema vlaka ustrezajo vsaj zadevnim zahtevam standarda EN 15734-1.
Ta evropski standard se uporablja za:
–   nove vlake z velikimi hitrostmi;
–   nove konstrukcije obstoječih tipov vozil;
–   večje obnove zgoraj navedenih vozil, če obnova vključuje preoblikovanje ali obsežno spremembo zavornega sistema zadevnega vozila.
Zahteve za funkcionalno preskušanje, določene v tem dokumentu, predvidevajo, da so vozila opremljena z arhitekturo zavornega sistema v skladu z načeli UIC za upravljanje zračnih zavornih vodov.
Hitri vlak je mogoče opremiti z alternativnimi arhitekturami zavornih sistemov, ki ne uporabljajo upravljanja zavornih vodov. V takih primerih je treba določiti enakovredne zahteve za preskušanje, da se preizkusi funkcionalna učinkovitost vgrajenega zavornega sistema.
