Railway Brake Friction Material Characterisation

This test characterises the friction properties and thermal behavior of brake pads and brake blocks used in railway braking systems, ensuring consistent performance and safety across diverse operating conditions. The test evaluates friction coefficients at various temperatures, pressure levels, and speeds to validate that materials meet performance specifications for both passenger and freight applications. Accurate characterisation is essential for brake system designers to predict braking performance and prevent brake fade or instability. Accreditation guarantees that testing is performed with validated equipment and procedures, supporting regulatory compliance and safe brake system design.

What it measures

Friction coefficient at varying temperatures
Friction coefficient dependence on pressure and sliding speed
Thermal fade and recovery characteristics
Wear rate and material degradation
Vibration and noise generation potential
