Railway applications - Railway rolling stock - Buffers

This European Standard defines the requirements for buffers with 105 mm, 110 mm and 150 mm stroke for vehicles or units which use buffers and screw coupling at the coupling interface with other interoperable rolling stock. It covers the functionality, interfaces and testing procedures, including pass fail criteria, for buffers.
NOTE   Typically, buffers with a stroke of 105 mm are used on freight wagons and locomotives, buffers with a stroke of 110 mm are used on coaches and locomotives and buffers with a stroke of 150 mm are used on freight wagons.
It defines the different categories of buffers, the space envelope, static and dynamic characteristics and energy absorption.
It includes a calculation method to determine the minimum size of the buffer head to avoid override between buffers.
It defines the static and dynamic characteristics of the elastic systems.
It also defines the requirements for buffers with integrated crash elements (crashworthy buffers) for tank wagons only according to RID.
The requirements of this European Standard also apply to locomotives and passenger coaches which have to meet the crashworthiness requirements of EN 15227 for buffers in normal service only. The properties for the energy absorbing function are defined in EN 15227 and the requirements specified in Clause 7 for tank wagons according to RID are not applicable to locomotives and passenger coaches.
Diagonal buffers are excluded from this European Standard.
For vehicles which have to comply with crashworthiness requirements (locomotives, cab cars or passenger coaches according to EN 15227, tank wagons according to RID), typically crashworthy buffers (buffers with a deformable housing and/or the need for an opening in their mounting flange) or buffers which form part of a combined system consisting of a special buffer (e.g. middle flange buffer) and a deformation element are used. For these types of buffers, interoperability is possible, but interchangeability with freight wag

Bahnanwendungen - Schienenfahrzeuge - Puffer

Diese Europäische Norm definiert die Anforderungen an Puffer mit 105 mm, 110 mm und 150 mm Hub für
Fahrzeuge und Einheiten, die Puffer und Schraubenkupplungen verwenden und an Kupplungsschnittstellen
mit Schienenfahrzeugen im grenzüberschreitenden Verkehr zum Einsatz kommen. Sie umfasst die Funktionsmerkmale,
Schnittstellen und Prüfverfahren einschließlich der Abnahmekriterien für Puffer.
ANMERKUNG Üblicherweise werden Puffer mit einem Hub von 105 mm für Güterwagen und Lokomotiven, Puffer mit
einem Hub von 110 mm an Reisezugwagen und Lokomotiven und Puffer mit einem Hub von 150 mm für Güterwagen
genutzt.
Sie definiert die einzelnen Pufferkategorien, den erforderlichen Hüllraum, statische und dynamische Merkmale
und die Energieaufnahme.
Sie beinhaltet weiterhin eine Berechnungsmethode zur Bestimmung der Mindestgröße des Puffertellers, um
ein Überpuffern zu vermeiden.
Außerdem werden die statischen und dynamischen Merkmale der Federsysteme definiert.
Weiterhin definiert diese Norm die Anforderungen an in Puffer integrierte Crashelemente (kollisionssichere
Puffer) für Kesselwagen ausschließlich nach den Bestimmungen des RID.
Die Anforderungen dieser Europäischen Norm gelten auch für Lokomotiven und Reisezugwagen, die die
Anforderungen der EN 15227 zur Kollisionssicherheit erfüllen müssen, und für Puffer bei normalem Betrieb.
Die Eigenschaften der Energieaufnahmefunktion sind in der EN 15227 definiert. Die Anforderungen, die in
Abschnitt 7 für Kesselwagen nach RID festgelegt sind, gelten nicht für Lokomotiven und Reisezugwagen.
Diagonalpuffer sind von dieser Europäischen Norm ausgenommen.
Für Fahrzeuge, die den Anforderungen der Kollisionssicherheit unterliegen (Lokomotiven, Steuerwagen und
Reisezugwagen nach der EN 15227, Kesselwagen nach RID), werden übliche kollisionssichere Puffer (Puffer
mit einem verformbaren Gehäuse und/oder dem Bedarf einer Öffnung in ihrem Montage-Flansch) oder Puffer,

Applications ferroviaires - Wagons - Tampons

La présente norme définit les exigences relatives aux tampons de 105 mm, 110 mm et 150 mm de course pour les véhicules ou les unités, qui utilisent des tampons et des attelages à vis pour être couplés avec d’autres matériels roulants interopérables. La présente norme couvre les fonctionnalités, les interfaces et les procédures d’essai, y compris les critères de réussite ou d’échec, des tampons.
NOTE     Typiquement les tampons avec une course longue de 105 mm sont utilisés sur les wagons de marchandises et les locomotives, les tampons d’une course longue de 110 mm sont utilisés sur les véhicules voyageurs et les locomotives, les tampons d’une course longue de 150 mm sont utilisés sur les wagons de marchandises.
Elle définit les différentes catégories de tampons, l'encombrement, les caractéristiques statiques et dynamiques et l’absorption d’énergie.
Elle inclut une méthode de calcul permettant de déterminer la taille minimale du plateau de tampon afin d’éviter un chevauchement des tampons.
Elle définit également les caractéristiques statiques et dynamiques des systèmes élastiques.
Elle définit les exigences relatives aux éléments de choc intégrés dans les tampons pour les wagons citernes conformes à la réglementation RID.
Les exigences de la présente norme européenne s’appliquent aussi aux locomotives et véhicules voyageurs, qui doivent remplir les exigences anti crash conformément à la norme EN 15227, seulement pour les tampons en utilisation de service normal. Les propriétés de la fonction « absorption d’énergie » sont définies dans la norme EN15227 et les exigences énoncées dans l’Article 7 pour les wagons citernes conformément à la réglementation RID ne sont pas applicables aux locomotives et aux véhicules voyageurs.
Les tampons diagonaux ne font pas partie du présent document.
