The main objective of brake testing is to determine the braking performance of railway vehicles. Braking performance may be assessed by determining stopping distances, brake weights or equivalent decelerations.
Braking systems performance: Sustituir introducción por “CETEST is able to perform Braking performance and functionality tests according to international standards and TSI:
- Functional requirement tests according to UIC547 and UIC540 standards,
- Braking performance assessment tests according to UIC544-1 and TSI LOC&PAS standards,
- Wheel slide protection tests according to EN15595:2020 standard,
- Determination of braked weight percentage and braking distance according to UIC544-1 standard.
Since the stopping distance varies according to vehicle conditions (load case, degraded modes, etc.) and brake type (service brake, emergency brake, parking brake, etc.), then vehicles should be tested under combinations of different vehicle conditions and brake types.
Measurements involve speed, brake disks/wheels temperature, reservoir/cylinder pressures, acceleration, brake activation and other parameters, in order to fully understand the vehicle’s braking behavior under each test configuration.
Note that the tested vehicle can be a full test consist or a single trailer car/wagon and can be tested via slip tests, with a coupling designed specifically for those applications.
