EN 15734-2
High-Speed Railway Braking System Performance Testing
This test method establishes performance criteria and evaluation procedures for braking systems installed on high-speed rolling stock operating at speeds exceeding 200 km/h. It assesses braking distances, deceleration rates, emergency brake effectiveness, and thermal capacity under various operational scenarios and environmental conditions. The test is essential for ensuring passenger safety and operational reliability on high-speed rail networks across Europe. Accreditation guarantees that testing laboratories can verify compliance with Technical Specifications for Interoperability (TSI) and validate that braking systems meet stringent European safety requirements.
What it measures
- Braking distance and deceleration rates
- Emergency brake effectiveness and response time
- Thermal stability and fade characteristics
- Braking system energy dissipation capacity
- Performance consistency across repeated brake applications
