Testing solution for the measurement of brake wear emissions

Brake Wear Key Visual

Brake wear is a major source of non-exhaust, traffic-related particulate matter (PM) and, due to its increasing contribution to overall PM emissions, is increasingly in the spotlight of regulatory bodies.

EU regulations will include particulate emissions due to brake wear in the certification of vehicles, necessitating the precise measurement of particle mass (PM) and particle number (PN) of brake wear. A draft Global Technical Regulation (GTR) is available.
The AVL Brake Wear Testing Solution is an all-in-one testing solution for the measurement of particle mass and number concentration of braking systems using a high-end brake dynamometer under variable, highly dynamic testing conditions.

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 is currently being validated and will be implemented as a new global testing regulation at the start of 2023. 
Based on this, GTR particle mass and particle number (PM10, PM2.5 and CPC-based PN10 measurement) must be measured over a specified brake cycle on a brake dyno.
