(e)introductionnormative 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 informative annex i);c)definition of delivery conditions (see informative annex j). here, a choice is given to the supplier of either:atraditional deliveryprocedurewith acontrolbybatchsamplingasinexisting documents (see j.4), ora delivery procedure using quality assurance concepts (see j.5).1scopethis 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 axlein 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 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 anden 13104note different values for some characteristics may be agreed if a particular process of fabrication (e.g cold rolling, shot peening) has an influence on them.1) n for the normalized metallurgical conditiont for the quenched and tempered metallurgical condition5en 13261:2003 (e)2normative
