Scope
UIC 540-1, 540-2
Pneumatic Brake Systems for Railway Rolling Stock
UIC 540 establishes technical requirements and test procedures for pneumatic (air) brake systems on freight and passenger trains throughout the European railway network. This standard covers design, performance, safety, and interoperability of brake components including cylinders, valves, pipes, and control systems. Railway manufacturers, brake suppliers, and infrastructure operators require testing to ensure compliance, validate equipment compatibility across different networks, and demonstrate safety performance. Accredited testing provides independent verification that brake systems meet stringent safety and reliability standards essential for railway operations.
What it measures
- Brake force and braking deceleration (m/s²)
- Pressure response and valve actuation times
- Pipe and connection integrity and leakage rates
- Brake cylinder performance and seal integrity
- System compatibility and inter-car coupling performance
