Railway applications - Braking - Distributor valves and distributor-isolating devices

This European Standard applies to distributor valves and distributor-isolating devices. The distributor valves contained in this European Standard are of graduated release type. Direct release types are not included. Functionally they are regarded as not containing relay valves of any type, even if the relay valves are physically an integral part of the distributor valves. This European Standard applies to both distributor-isolating devices mounted separate from the distributor valve and distributor-isolating devices integral with the distributor valve. This European Standard specifies the requirements for the design, testing and quality assurance of distributor valves and distributor-isolating devices. For interoperable freight wagons, these devices which are operated by compressed air according to EN 14198 are assessed according to the respective technical specification of interoperability.

Bahnanwendungen - Bremse - Steuerventile und Bremsabsperreinrichtungen

Dieses Dokument gilt für Steuerventile, die nach den TSI Spezifikationen als Interoperabilitätskomponenten für Druckluftbremsen von interoperablen Schienenfahrzeugen, die durch Druckluft betätigt werden, bewertet werden.
Die Steuerventile, wie sie in diesem Dokument enthalten sind, sind von mehrlösiger Bauart. Einlösige Ventile werden nicht behandelt.
Die Betrachtung der Funktionen erfolgt so als ob kein Relaisventil enthalten wäre, auch wenn die Relaisventile physikalisch in das Steuerventil integriert sein können.
Dieses Dokument definiert die Anforderungen an Konstruktion, Abmessungen, Prüfung und Qualitätssicherung des Steuerventiles. Diese Anforderungen können nicht ausreichend genau beschrieben werden, um die fachgerechte Herstellung oder zweckmäßige Konstruktion sicherzustellen. Daher ist jeder Hersteller dafür verantwortlich, alle notwendigen Schritte zu unternehmen, die die Qualität von Konstruktion, Bearbeitung und Herstellung im Einklang mit fachgerechter Ingenieurspraxis sowie ausreichender Fertigungsqualität sicherstellen.

Applications ferroviaires - Freinage - Distributeurs de freinage et robinet d'isolement

Le présent document s’applique aux distributeurs de freinage et aux robinets d’isolement.
Les distributeurs de freinage décrits dans la présente norme européenne sont de type à desserrage gradué.
Les types à desserrage direct ne sont pas couverts.
Sur un plan fonctionnel, ils sont considérés comme ne comportant pas de relais pneumatique d’aucune sorte, même
si les relais pneumatiques font partie intégrante des distributeurs de freinage.
La présente norme européenne s’applique aux robinets d’isolements montés séparément du distributeur de freinage
ainsi qu’aux robinets d’isolement intégrés au distributeur de freinage.
Elle spécifie les exigences à respecter pour la conception, les essais et l’assurance qualité des distributeurs
de freinage et des robinets d’isolement.
Pour les wagons de marchandises interopérables, ces dispositifs fonctionnant à l’air comprimé conformément
à l’EN 14198, sont évalués selon les Spécifications Techniques d’Interopérabilité concernées.

Železniške naprave - Zavore - Krmilni ventili in naprave za ločitev krmilnih ventilov od zavornega voda

Ta evropski standard velja za krmilne ventile in naprave za ločitev krmilnih ventilov od zavornega voda. Krmilni ventili, ki jih vključuje ta evropski standard, so ventili s postopnim razbremenjevanjem. Ventili z neposrednim razbremenjevanjem niso vključeni. Glede njihove funkcionalnost velja, da ne vsebujejo relejnih ventilov, tudi če so ti fizično integralni del krmilnih ventilov. Ta evropski standard velja za naprave za ločitev krmilnih ventilov od zavornega voda, nameščene ločeno od krmilnega ventila, in za naprave za ločitev krmilnih ventilov od zavornega voda, integrirane s krmilnim ventilom. Ta evropski standard določa zahteve za načrtovanje, preskušanje in zagotavljanje kakovosti krmilnih ventilov in naprav za ločitev krmilnih ventilov od zavornega voda. Pri medobratovalnih tovornih vagonih se naprave, ki delujejo na stisnjeni zrak v skladu z EN 14198, ocenjujejo glede na ustrezno tehnično specifikacijo medobratovalnosti.
