BAS EN 15746-2:2011

This European Standard applies to discs designed to be fitted to rail vehicles used on the main national networks, urban networks, underground railways, trams, private networks (regional railways, company railways, etc.). This European Standard comprises a basic test of disc performance. The disc is tested for energy dissipation, power conversion and ventilation characteristics as well as mechanical integrity. The disc and pad interaction couple, which is used as a reference, are defined. The classification qualifies a brake disc with the defined brake pads by dynamometer tests for type validation by in-service experience for up to one year without additional tests in the defined application class. It does not give rules for the application and the brake performance in specific trains. For this purpose additional tests may be necessary. The classes may give a recommendation for a preliminary selection of the required brake equipment to the vehicle designer. Except for the frictional performances, the tests defined in this standard are type test according EN 14535 1 and EN 14535-2.
