UIC 541-5

Railway Disc Brake Pad Homologation

UIC 541-5 specifies the technical requirements and homologation conditions for disc brake pads used in railway rolling stock. This standard establishes performance criteria including friction coefficient stability, wear resistance, thermal durability, and mechanical properties under dynamic braking loads. Testing ensures brake pads function safely across diverse operational temperatures and moisture conditions encountered in European railway networks. Accreditation for this test is critical for brake pad manufacturers and railway operators to guarantee compatibility and safety across standardized European rail systems.

What it measures

  • Friction coefficient stability across temperature ranges
  • Brake pad wear rate and material loss
  • Thermal durability and fade resistance
  • Mechanical strength and adhesion to backing plates
  • Moisture absorption and water resistance
