Describes the characteristics of new wheelsets for use on European networks: Applies to wheelsets comprising elements that conform to the following European Standards: [3/4] EN 13262 for wheels; [3/4] EN 13261 for axles; Not fully applies to wheelsets undergoing maintenance. Some characteristics are given as a function of a category 1 or of a category 2. Category 2 can be divided into sub-categories (2a and 2b) to specify certain characteristics. Category 1 is generally chosen when the operating speed exceeds 200 km/h. The wheelset then comprises wheels and axle of category 1 as specified in EN 13262 for the wheels and EN 13261 for the axles.
