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. 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 wagon buffers is not required, and therefore the requirements of 5.2 (Fixing on vehicle and interchangeability), 5.3 (Buffer dimensions) do not apply, those of 5.4 (mechanical characteristics of buffers) and 5.6 (marking) apply with restrictions.

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. (...)

Železniške naprave - Železniška vozila - Odbojniki

Ta evropski standard opredeljuje zahteve za odbojnike s 105-, 110- in 150-mm hodom za vozila ali enote, ki na vmesniku za sklapljanje z drugimi medobratovalnimi tirnimi vozili uporabljajo odbojnike in vijačne spenjače. Zajema funkcionalnost, vmesnike in postopke preskušanja za odbojnike, vključno z merili za uspešnost in neuspešnost. Opredeljuje različne kategorije odbojnikov, ohišje, statične in dinamične lastnosti ter absorpcijo energije. Vključuje metodo izračuna za določanje minimalne velikosti glave odbojnika, ki preprečuje prekrivanje med odbojniki. Opredeljuje statične in dinamične lastnosti elastičnih sistemov. Opredeljuje tudi zahteve za odbojnike z vgrajenimi elementi za trčenje (odbojniki za zagotavljanje pasivne varnosti), le za vagone s cisterno v skladu z RID. Zahteve tega evropskega standarda veljajo tudi za lokomotive in potniške vagone, ki morajo ustrezati zahtevam EN 15227 za zagotavljanje pasivne varnosti, le za odbojnike pri običajni uporabi. Lastnosti funkcije za absorpcijo energije so opredeljene v EN 15227, zahteve, določene v Klavzuli 7 za vagone s cisterno v skladu z RID, pa ne veljajo za lokomotive in potniške vagone. Ta evropski standard ne vključuje diagonalnih odbojnikov. Pri vozilih, ki morajo ustrezati zahtevam za zagotavljanje pasivne varnosti (lokomotive, vozniški vagoni ali potniški vagoni v skladu z EN 15227, vagoni s cisterno v skladu z RID), se praviloma uporabljajo odbojniki, ki zagotavljajo pasivno varnost (odbojniki z deformabilnim ohišjem in/ali odprtino v prirobnicah za vgradnjo), ali odbojniki, ki so del kombiniranega sistema, sestavljenega iz posebnega odbojnika (npr. odbojnika s centralno prirobnico) in deformabilnega elementa. Pri tovrstnih odbojnikih je medobratovalnost mogoča, vendar medsebojna zamenljivost z odbojniki tovornih vagonov ni potrebna, zato zahteve točk 5.2 (Pritrjevanje na vozilo in medsebojna zamenljivost), 5.3 (Mere odbojnikov) ne veljajo, zahteve točk 5.4 (mehanske lastnosti odbojnikov) in 5.6 (označevanje) pa veljajo z omejitvami.

Introduction The main purpose of normative documents used until now for the delivery of buffers (UIC leaflets, national standards) was a complete definition of the acceptance procedures and of the buffers characteristics which were to be verified. Product qualification was sometimes mentioned but the procedures used and the product characteristics to be verified during qualification were not given. This European Standard addresses all buffer characteristics that are assembly characteristics and finished product characteristics and do not arise from a choice of design parameters such as diameters, interferences, materials etc.
The buffer and its components are delivered by suppliers that operate a quality system. NOTE The quality systems used should offer equivalence with EN ISO 9001. This European Standard is based on UIC 526-1, UIC 526-3, UIC 527-1, UIC 528, UIC 573, UIC 827-1 and UIC 827-2. For coaches the technical content at present is limited to that given in UIC 528:2007.
