Automatic Variable Load Brake Testing
This test defines specifications for automatic variable load braking systems that adjust braking force proportionally to the vehicle's loading condition, optimizing stopping distance and wheel adhesion. The standard covers the design, functionality, and performance requirements of automatic load-sensing brake control equipment fitted to freight and passenger trains. Testing verifies that braking force automatically adjusts across the range from empty to fully loaded conditions, enhancing safety and reducing wheel slide risk. Accreditation for this test is critical for manufacturers of brake control systems and railway operators ensuring consistent, safe braking performance regardless of train loading.
What it measures
- Load-proportional braking force adjustment mechanisms
- Response characteristics across loading range
- Wheel adhesion optimization and anti-lock performance
- System reliability and fail-safe functionality
- Pressure modulation and control accuracy
