Proposal to establish approval requirements for the particle emissions of replacement brake pads (based on the laboratory method established by GTR 24).

Proposal to enable the approval of vehicles equipped with an Automated Driving System under the new UN Regulation on brake particle emissions.

Proposal to clarify the selection of the wheel load among vehicles with identical brake assemblies for particle emissions testing.

Proposal to establish a UN Global Technical Regulation for measuring brake particulate matter and particle number emissions from heavy-duty vehicles. The regulation defines laboratory test procedures using a brake dynamometer and the Worldwide Harmonized Heavy-Duty Vehicles Brake Cycle (WHBC), encompassing 20,353 seconds with 246 brake events across three driving segments. Tests require brake bedding with six WHBC repetitions, followed by emissions measurement. Laboratories must measure PM10 and PM2.5 mass gravimetrically and total and solid particle numbers (TPN10, SPN10) using particle counters. Technical specifications cover brake enclosure design, sampling tunnel configuration, climatic control, instrumentation calibration, and data reporting requirements to ensure reproducible and comparable brake emissions testing across regions.
