including requirements related to measurement technology
and testing methodology for brake emissions. The core of this
testing methodology is a testbed for brakes, which is used for
a sTecially defined testing cycle, tLe ;orldwide ,armoni^ed
Light Vehicles Test Procedure (WLTP) Brake Cycle. By the

supports other labs with measurement technology.
Our Active Involvement in Design
AVL has been a world leader in the exhaust emissions
segment for many years. We also enjoy a leading role with
regard to brake particulate measurement systems, based
on our profound understanding of the physical behavior
of the particles that occur during the braking process. We
are represented in all relevant EU bodies and also apply our
expertise to help design the future of mobility in the non-
exhaust emissions segment.
AVL Brake Emission Test Systems
At the same time, we have developed our own AVL Brake
Emission Test Systems solution, delivering replicable and
comparable measurement results thanks to comprehensive
optimization of the entire measurement chain, all in a GTR-
compliant manner. The modular design and the self-contained
subsystems allow our solution to be tailored to each customer.
We also have a range of simulation tools for all current
development requirements. We can also repurpose testbeds
previously used to measure internal combustion engine
emissions so that these can be used for brake emission testing
– while keeping investment to a minimum. Major OEMs already
rely on AVL’s proven expertise.
Looking Ahead
The emissions legislation leads to the assumption that brake
emissions testing will not be restricted to component tests
on the testbed, but will also be conducted during real driving
conditions in the medium term. AVL has initiated development
in this area as well, building on the successes enjoyed in
emissions reduction.
“We offer brake emissions
measurement, (atribute)
engineering, certification, and
homologation – from a single
provider.”
Exhaust gases are no longer the cause of the majority of particulate
emissions, which are now often produced by tire, road and brake abrasion.
And it is the latter that offers significant potential for reduction. From 2026,
statutory provisions will be in place for the first time, in the form of Euro 7.
