Railway applications - Braking - Relay valves

This European Standard is applicable to relay valves designed to control the brake cylinder pressure of compressed air brakes fitted to railway vehicles, in association with an air brake distributor valve or other control device, and in response to a change in vehicle load that is either continuously variable or in two stages i.e. empty - loaded.
Relay valves operating with other pressures, in particular the brake pipe pressure, are not included.
This European Standard specifies the requirements for the design, manufacture and testing of relay valves.

Bahnanwendungen - Bremse - Relaisventile

Diese Europäische Norm gilt für Relaisventile zur Steuerung des Bremszylinderdruckes von Druckluftbremsen
in Eisenbahnfahrzeugen in Zusammenarbeit mit einem Bremssteuerventil oder einem anderen Steuerelement,
abhängig von einer Veränderung der Fahrzeugbeladung, die entweder autokontinuierlich oder
zweistufig, d. h. „leer“ — „beladen“, erfolgt.
Relaisventile, die mit anderen Betriebsdrücken, insbesondere dem Druck in der Hauptluftleitung, arbeiten,
sind hierin nicht erfasst.
In dieser Europäischen Norm werden die Anforderungen für die Konstruktion, die Herstellung und die Prüfung
von Relaisventilen festgelegt.

Applications ferroviaires - Freinage - Relais pneumatiques

La présente Norme européenne s’applique aux relais pneumatiques conçus pour commander la pression du
cylindre des freins à air comprimé montés sur les véhicules ferroviaires, en association avec un distributeur de
freinage à air ou un autre dispositif de commande et en fonction des variations de la charge du véhicule. La
pression commandée peut varier soit continuellement en fonction des variations de la charge, soit par paliers
à 2 niveaux (un niveau pour l’état de charge « vide » et un autre pour l’état de charge « chargé »).
Les relais pneumatiques fonctionnant avec d’autres pressions, notamment la pression de conduite générale,
ne sont pas considérés dans cette norme.
La présente Norme européenne spécifie les exigences relatives à la conception, à la fabrication et aux essais
des relais pneumatiques.
