Railway applications - Brake discs for railway rolling stock - Part 3: Brake discs, performance of the disc and the friction couple, classification

Scope

This European Standard applies to brake discs designed to be fitted to railway vehicles.
This document comprises a type test of brake disc performance. The brake disc is tested for energy conversion and dissipation, ventilation characteristics as well as mechanical integrity.
The classification qualifies a brake disc in conjunction with the defined brake pad by dynamometer tests which simulates up to one year in service when operating in the defined application class. It does not define the application and the brake performance in specific trains.
NOTE For this purpose, additional tests may be necessary.
For the application of brake discs on railway vehicles it is not mandatory to use classified brake discs.
Classified brake discs can be validated for the use on railway vehicles for higher performance applications with additional tests.
This document describes the type test procedure for brake disc classification as specified in EN 14535 1 and EN 14535 2.
