Railway applications - Wheelsets and bogies - Axles - Product requirements

This European Standard specifies the characteristics of axles for use on European networks. It defines characteristics of forged or rolled solid and hollow axles, made from vacuum-degassed steel grade EA1N1 that is the most commonly used grade on European networks. For hollow axles, this standard applies only to those that are manufactured by machining of a hole in a forged or rolled solid axle In addition, the particular characteristics for axles in grade EA1T1 and EA4T1 are given in Annex A. Two categories of axle are defined, category 1 and category 2. Generally, category 1 is chosen when the operational speed is higher than 200 km/h. This standard is applicable to axles that are designed in accordance with the requirements of EN 13103 and EN 13104.

Bahnanwendungen - Radsätze und Drehgestelle - Radsatzwellen - Produktanforderungen

Diese Europäische Norm legt die Eigenschaften von Radsatzwellen für den Einsatz auf europäischen Netzen fest.
Sie beschreibt die Eigenschaften für geschmiedete oder gewalzte Radsatzwellen aus vakuumentgastem Stahl der Güte EA1N1), der bei den europäischen Bahnen am meisten verwendete Stahlgüte. Bei Hohlwellen gilt diese Norm nur für diejenigen, die durch das Bohren eines Loches in eine geschmiedete oder gewalzte Vollwelle gefertigt werden.
Zusätzlich sind die für die Radsätze der Stahlgüten EA1T1) und EA4T1) zu berücksichtigende Sonderwerte der Charakteristika im Anhang A gegeben.
Es werden zwei Kategorien von Radsatzwellen unterschieden: Kategorie 1 und Kategorie 2. Im Allgemeinen wird die Kategorie 1 gewählt, wenn die Fahrgeschwindigkeit über 200 km/h liegt.
Diese Norm gilt für Radsatzwellen, die nach den Anforderungen von EN 13103 und EN 13104 konstruiert sind.
ANMERKUNG Für bestimmte Charakteristika können andere Werte akzeptiert werden, sofern diese durch besondere Fertigungsbedingungen (z. B. Kaltschmieden, Kugelstrahlen) beeinflusst werden.

Applications ferroviaires - Essieux montés et bogies - Essieux-axes - Prescriptions pour le produit

La présente Norme Européenne spécifie les caractéristiques des essieux-axes, utilisés sur les réseaux européens.
Elle définit les caractéristiques des essieux-axes fabriqués par forgeage ou par laminage, en acier dégazé sous vide, de nuance EA1N )  qui est la nuance la plus utilisée sur les réseaux de chemins de fer européens. Pour les essieux-axes creux cette Norme s'applique seulement à ceux qui sont obtenus par usinage du trou dans un essieu-axe plein forgé ou laminé.
En complément, les valeurs particulières des caractéristiques à prendre en compte pour les essieux de nuance EA1T1) et EA4T1) sont données en Annexe A.
Deux catégories d'essieux axes sont distinguées, la catégorie 1 et la catégorie 2. Généralement, la catégorie 1 est utilisée pour des vitesses de circulation supérieures à 200 km/h.
Cette Norme s'applique aux essieux-axes dont la conception est conforme aux règles définies dans l’EN 13103 et l’EN 13104.
NOTE   Des valeurs différentes pour certaines caractéristiques peuvent être acceptées lorsque des conditions particulières de fabrication (par exemple forgeage à froid, grenaillage de précontrainte) ont une influence sur celles-ci.

Železniške naprave - Kolesne dvojice in podstavni vozički - Osi - Zahtevane lastnosti proizvoda

Ta evropski standard določa značilnosti osi za uporabo v evropskih omrežjih. Opredeljuje značilnosti kovanih ali valjanih trdnih in votlih osi, narejenih iz vakuumsko razplinjenega jekla vrste EA1N1, ki je najpogosteje uporabljena vrsta jekla v evropskih omrežjih. Pri votlih oseh ta standard velja le za osi, narejene s strojno izdelavo luknje v kovano ali valjano trdno os. Poleg tega so v Dodatku A navedene posebne značilnosti osi iz vrst jekla EA1T1 in EA4T1. Opredeljeni sta dve kategoriji osi, kategorija 1 in kategorija 2. Kategorija 1 se običajno izbere, kadar hitrost obratovanja presega 200 km/h. Ta standard velja za osi, načrtovane v skladu z zahtevami EN 13103 in EN 13104.

EN 13261:2009+A1:2010 (E) 6 Introduction Normative documents which have been used until now in Europe for axle delivery (UIC leaflets, national standards) had, for the main purpose, a complete definition of delivery procedures and axle characteristics that were to be measured.
Product qualification was sometimes mentioned, but the procedures and the characteristics that had to be verified for the qualification were not given.
This standard addresses these issues by:
a) definition of all axle characteristics; these are verified either during qualification or delivery of the product (see clause 3); b) definition of qualification procedures (see Annex I); c) definition of delivery conditions (see Annex J); here, a choice is given to the supplier of either: 1) a traditional delivery procedure with a control by batch sampling as in existing documents (see J.5),
or; 2) a delivery procedure using quality assurance concepts (see J.6). SIST EN 13261:2009+A1:2010

1 Scope This European Standard specifies the characteristics of axles for use on European networks.
It defines characteristics of forged or rolled solid and hollow axles, made from vacuum-degassed steel grade EA1N1 that is the most commonly used grade on European networks. For hollow axles, this standard applies only to those that are manufactured by machining of a hole in a forged or rolled solid axle
In addition, the particular characteristics for axles in grade EA1T1 and EA4T1 are given in Annex A.
Two categories of axle are defined, category 1 and category 2. Generally, category 1 is chosen when the operational speed is higher than 200 km/h.
This standard is applicable to axles that are designed in accordance with the requirements of EN 13103 and EN 13104.
NOTE Different values for some characteristics may be agreed if a particular process of fabrication (e.g. cold rolling, shot peening, shot peening, steel cleanliness, reduction ratio, improved material properties from melting and heat treatment processes, etc.) has an influence on them. 2 Normative references The following referenced documents are indispensable for the application of this document.
