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 requirements by:
a)
definition of all the wheel characteristics. These are either verified during the qualification or delivery of the product (see clause 3);
b)
definition of the qualification procedures (see informative annex E);
c)
definition of the delivery conditions (see informative annex F). 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 F.4), or
-
a delivery procedure using quality assurance concepts (see F.5).
The standard defines the wheel product qualification, the technical approval procedure is not within the scope of this standard.
1 Scope This European Standard specifies the characteristics of railway wheels for use on European networks.
Four steel grades, ER6, ER7, ER8 and ER9 are defined in this standard.
Some characteristics are defined according to a category 1 or a category 2. Category 1 is generally chosen when the train speed is higher than 200 km/h.
These categories can sometimes be subdivided, depending upon the characteristics.
This standard is applicable to solid forged and rolled wheels which are made from vacuum degassed steel and have a chilled rim. They are to have already been used in commercial conditions on a European network in a significant quantity, or to have satisfied a technic
