Railway Composite Brake Blocks - Requirements
This test method establishes performance requirements and acceptance criteria for composite (non-asbestos) brake blocks used in freight wagon braking systems. It evaluates friction characteristics, thermal stability, wear resistance, and compatibility with brake disc or wheel surfaces under representative operational conditions. Freight operators and brake block manufacturers use this test to ensure component reliability and safe braking performance in heavy-duty rail transport. Accreditation is critical for laboratories conducting brake block qualification testing to provide independent verification of compliance with European technical specifications for freight wagon safety.
What it measures
- Coefficient of friction under varied temperatures
- Wear rate and durability characteristics
- Thermal stability and fade resistance
- Compatibility with disc or wheel materials
- Dimensional stability and surface integrity
