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 be sometimes 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 technical approval procedure according to prEN 13979-1 for their design.
