Brake and tire emissions testing

Mastering non-exhaust emissions for Euro 7

How to reduce particulate emissions intelligently, efficiently and flexibly? We are your partner for the new requirements of Euro 7 legislation with regard to brake and tire emissions. With our test center, our development services and our many years of automotive expertise, we will accompany and advise you all the way to your successful Euro 7 homologation.

Take a breath

In order to reduce particulate matter from brake and tire abrasion in the air, the European Parliament has voted for a regulation of these non-exhaust emissions for the first time. The expansion of electrically powered vehicles will ultimately eliminate exhaust emissions completely. Therefore, the focus is shifting to non-exhaust emission sources.

Holistic Engineering & Consulting

In order to comply with limit values, we support you in the selection of friction materials and secondary measures. We offer a detailed analysis of the underlying factors influencing wear and particle formation. And thanks to our excellent knowledge of trends and technologies, you can rely on us to react flexibly and avoid costly detours.

Virtual development methods

Using CAE methods, we optimize the efficiency of secondary measures such as particle capture devices for brake and tire particles and support you in the design of the system with regard to thermal and comfort requirements as well as wear and fatigue resistance.

Data driven emissions reduction

We develop prediction models and thus a digital twin of the braking system as well as the tire with regard to wear and emission behavior. We derive control strategies, e.g. for regenerative braking. Traffic control can be optimized using V2X methods.

Features at a glance

Our services for clean braking

  • Testing at our accredited test facility: We carry out brake emission tests in accordance with the UN-GTR No. 24 test procedure, including preparation and execution. We create detailed test reports automatically according to your specifications. In future, we will offer Euro 7 homologation tests and conformity tests.
  • Comprehensive testing in a diverse testing infrastructure: At IAV, you benefit from extensive experience in the development, design, testing and integration of chassis components. We have many years of expertise in measuring exhaust emissions, which we build on with non-exhaust emissions. You have access to our component test benches for your performance and NVH tests as well as to complete vehicle tests on the road and on chassis dynamometers.
