In 2022, just 15 % of overall particle related emissions originated from the tailpipe were regulated. 85 % of the emissions were non-regulated and originated from sources such as brake wear, tire wear and road abrasion. To respond to this, a testing procedure for brake wear was validated and has been implemented as a new global testing regulation at the start of 2023.
Based on this, GTR-compliant particle mass and particle number (PM10, PM2.5 and CPC-based SPN & TPN measurement) must be measured over a specified brake cycle on a brake dyno.

The AVL Brake Emission Solution is an all-in-one testing solution to measure the particle mass and number concentration of braking systems on a high-end brake dynamometer under variable, highly dynamic testing conditions.
- Highly dynamic AVL Dynamometers
- Optimized sampling system for minimal particle loss
- APC technology in a device that measures particle number concentration, solid particle number (SPN), and total particle number (TPN)
- Cost-efficient gravimetric filter modules for PM 2.5 and PM 10
- Highest automation degree with the xChange option - up to 16 filter pucks can be stored and swapped automatically within the device between the tests
- Highest weighing accuracy using the optional AVL Filter Weighing Chamber
