Brake particle emission measuring system AVL Brake TS™

automatedfor braking padfor brake discs

Overview
The AVL Brake Emission Solution is a complete brake emissions testing system to measure particulate mass (PM2.5, PM10) and particle number concentration (SPN, TPN) from braking systems on a dynamic brake dynamometer. The solution integrates sampling hardware, APC particle-number technology, gravimetric PM modules and braking test engineering to deliver traceable, regulation-oriented results.

Regulatory context
Designed to address forthcoming regulatory frameworks (for example EURO 7), the system provides ISO17025-calibrated, traceable measurement chains suitable for compliance testing across light-duty, heavy-duty and full-electric vehicles. Documentation and certified procedures support homologation and audit processes.

AVL Brake Emission Solution - Key components

• Dynamic AVL brake dynamometers for highly variable, time-resolved profiles
• Optimized sampling system engineered to minimize particle losses and ensure homogeneous aerosol distribution
• APC-based particle-number measurement for PN, SPN and TPN
• Gravimetric filter modules for PM2.5 and PM10
• xChange automated filter handling (up to 16 filter pucks) for unattended test sequences
• Optional AVL Filter Weighing Chamber for laboratory-grade mass determination
