alle neuen Fahrzeugbauarten von selbstfahrenden Zügen mit thermischem oder elektrischem Antrieb, die bei einer Höchstgeschwindigkeit bis 200 km/h betrieben werden, im Folgenden vereinfachend EMUs/DMUs genannt;
alle größeren Grundüberholungen der vorstehend aufgeführten Fahrzeuge, wenn diese Neukonstruk¬tionen oder umfassende Änderungen des Bremssystems des betreffenden Fahrzeugs mit einschließen.
Diese Norm gilt nicht für:
lokbespannte Züge, die in EN 14198 festgelegt sind;
Fahrzeuge des öffentlichen Nahverkehrs, die in EN 13452 1 festgelegt sind;
Hochgeschwindigkeitszüge, die bei Geschwindigkeiten über 200 km/h betrieben werden und in EN 15734 1 festgelegt sind.

Applications ferroviaires - Systèmes de freinage pour trains automoteurs - Partie 1 : Exigences et définitions

La présente Norme européenne décrit les fonctions, les contraintes, les performances et le fonctionnement d'un système de freinage destiné à être utilisé dans des trains thermiques et électriques automoteurs circulant sur les voies du réseau de systèmes ferroviaires classiques européens.
La présente Norme européenne couvre :
-   toutes les nouvelles conceptions de véhicules des trains thermiques et électriques automoteurs circulant à une vitesse maximale de 200km/h, qui par la suite dans le texte sont simplement désignés par EMU/DMU (unité multiple électrique/unité multiple diesel) ;
-   toutes les grandes révisions des véhicules susmentionnés si celles-ci entraînent une reconception ou une transformation majeure du système de freinage du véhicule concerné.
La présente Norme ne couvre pas :
-   les trains tractés par locomotive qui sont spécifiés par l'EN 14198 ;
-   les matériels roulants des transports publics et suburbains qui sont spécifiés par l'EN 13452-1 ;
-   les trains à grande vitesse circulant à des vitesses supérieures à 200km/h qui sont spécifiées par l’EN 15734-1.
