Railway Brake Adhesion Performance Testing
This test method evaluates the adhesion performance of railway braking systems under controlled wet and contaminated rail conditions. It assesses the ability of brake systems to generate sufficient friction force while maintaining stable deceleration and preventing wheel lock-up. The test is fundamental for railway operators, brake manufacturers, and rolling stock producers to ensure safe braking performance across varying environmental conditions. Accredited testing ensures independent verification that brake systems meet critical safety requirements for European rail networks and comply with technical specifications for rolling stock.
What it measures
- Adhesion coefficient under wet conditions
- Adhesion coefficient with contaminated rail surfaces
- Brake force generation and stability
- Wheel slip and lock-up prevention
- Performance reproducibility across test cycles
