Brake emissions are a central focus of upcoming regulations, such as EU7 or CHN7: non-exhaust emissions, new limit values, and increasing requirements for measurement accuracy are leading about lasting changes to development and testing processes. ZF/AIP supports this development with a portfolio of test bench solutions and measurement systems—including regulation-compliant measurement technology for brake emissions. FAKT GmbH (Automotive Testing and Engineering Center) is using this technology to expand its measurement and testing capabilities for brake emissions at its Heimertingen location while ensuring high, repeatable, and reproducible data quality for customer projects. For this reason, FAKT opted for a combination of in-house development and high-quality components from ZF/AIP.
Precise and Reproducible Testing
As regulations continue to evolve, there is a growing need for measurement systems that not only “measure” but also deliver repeatable, comparable, reliable, and compliant results—even across different test fields, measurement campaigns, and test specimens. This is precisely where AIP brake emission measurement technology comes into play: as a specialized system for measuring brake particles and generating reproducible emission data as a basis for research, development, and homologation.
FAKT, as the largest independent EURO 7 test center, has decided to install a total of five systems as part of this collaboration. The system is based on a combination of FAKT’s proprietary enclosing (test specimen enclosure) and air conditioning technology, along with AIP’s measurement technology for brake emissions. The test bench is complemented by ZF’s electromechanical setup and automation to enable highly precise simulations of defined driving profiles.
This has laid the foundation for efficiently handling multiple measurement tasks—with consistent data throughout and a procedure compliant with regulations. The focus is on:
- Gravimetric PM determination for PM10 and PM2.5
- Measurement of solid and total particle number (SPN10 and TPN10)
- Compliant with GTR 24 / UN R 179
Brake emission measurement compliant with the latest GTR 24 and UNR 179 standards
With measurement technology specifically developed for brake dust emissions and compliant with GTR/UNR, AIP offers a future-proof solution: The PMC-DI enables gravimetric particle mass determination of PM10 and PM2.5; isokinetic sampling combined with precise mass flow controller technology guarantees reliable and reproducible results. The SPC-DI delivers particle number concentrations for SPN10 and TPN10 through proven CPC analysis and wear-free dilution stages. As an accredited calibration laboratory, AIP also provides ISO 17025-compliant calibrations for all relevant measurement parameters, thereby ensuring traceable measurement results and maximum process reliability.
Technical highlights of AIP measurement technology:
- PM10 and PM2.5 measurement in a compact combination device
- Regulation-compliant isokinetic sampling
- Precise mass flow controller technology
- PM and PN measurement technology in a compact 19-inch cabinet
- Efficient test bench operation thanks to a multisampling system
- Flow measurement with proven RDE technology
Higher throughput, robust data foundation, future-proof setup, new markets
With five systems for measuring brake emissions, FAKT is laying the groundwork for a standardized, future-proof, and efficient measurement infrastructure—with high repeatability and reproducibility of emission data and a clear alignment with current and future regulations.
Building on the successful implementation of brake emission measurement technology, the collaboration between FAKT and ZF/AIP is set to be further intensified in the future. In addition to the joint further development and optimization of the measurement technology, the focus is also on new application areas and market potential. Against the backdrop of growing regulatory requirements, the long-term goal is also to establish joint sales of such systems—particularly with an eye toward the Asian market. The aim is to leverage the combined system and application expertise of all partners in a targeted manner to offer customers high-performance, field-proven solutions on an international scale.
“For us at FAKT, close collaboration with ZF and AIP is a key success factor. Our testing technology stands for innovation, quality, and reliability. Together with our partners, we set standards for precision and comparability in Euro 7-related measurements. FAKT creates solutions that are already designed today to meet the requirements of future regulations.” (Xaver Fackler, Managing Director of FAKT GmbH, 2026)
