BEMS 3000

Measurement of brake emissions for TPN10 and SPN10 in accordance with ECE/TRANS/WP.29/GRPE/2023/4
In Europe, motor vehicles (light-duty vehicles) will in the future be tested for braking emissions in the WLTP cycle. The basis for this is the directive ECE/TRANS/WP.29/GRPE/2023/4, in short, UN GTR. The particle sizes in brake emissions are in the nanoparticle range of up to about 10 µm in concentrations of up to 2x106 particles/cm³.

Therefore, emissions in this size range are tested for TPN (Total Particle Number, solid and volatile) and SPN (Solid Particle Number, solid particles only, in particles/cm³). The PM2.5 and PM10 values (in µg/m³) are also considered.
