EN 13261:2003

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 EA1N ) 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 hollow axle
In addition, the particular characteristics for axles in grade EA1T1) and EA4T1) are given in annex A (normative).
Two categories of axle are defined, category 1 and category 2.  Generally, category 1 is chosen when operational speed in 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) have an influence on them

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 Sorte EA1N ), die bei den europäischen Bahnen am meisten verwendete Stahlsorte. Bei Hohlradsatz-wellen gilt diese Norm nur für diejenigen, die durch das Bohren eines Loches in eine geschmiedete oder gewalzte Radsatzvollwelle gefertigt werden.
Zusätzlich sind die für die Radsätze der Stahlgüten EA1T1) und EA4T1)  besonders zu berücksichtigenden Werte und Eigenschaften im Anhang A (normativ) gegeben.
Es werden zwei Radsatzwellenkategorien unterschieden: Kategorie 1 und Kategorie 2. Im allgemeinen wird die Kategorie 1 gewählt, wenn die Betriebsgeschwindigkeit über 200 km/h liegt.
Diese Europäische Norm gilt für Radsatzwellen, die nach den Anforderungen von EN 13103 und EN 13104 konstruiert sind.
ANMERKUNG   Andere Werte können für einige Eigenschaften vereinbart werden, wenn sie durch ein besonderes Herstellungsverfahren (z.B. Kaltschmieden, Kugelstrahlen) beeinflusst werden.

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

Cette norme s'applique aux essieux-axes dont la conception est conforme aux règles définies dans l'EN****** ou l'EN******.  Elle spécifie les caractéristiques des essieux-axes pleins et creux fabriqués par forgeage ou par laminage, en acier dégazé sous vide, de nuance EA1N 1) qui est la nuance la plus utilisée sur les réseaux de chemins de fer européens. Toutefois, les valeurs particulières des caractéristiques à prendre en compte pour les essieux de nuance EA1T1) et EA4T1) sont données en annexe A (normative).

Annexes H, I and J are informative. This document contains a bibliography. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and the United Kingdom.

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 informative annex I);
c) definition of delivery conditions (see informative annex J). Here, a choice is given to the supplier of either:  a traditional delivery procedure with a control by batch sampling as in existing documents (see J.4), or  a delivery procedure using quality assurance concepts (see J.5).
