Document GRPE-81-12
9 June 2020

The first part of the PMP Brake Protocol for measuring brake particle emissions and addresses items using a new WLTP-Brake Cycle in conjunction with an inertia dynamometer test. The PMP Brake protocol will include three sections aiming to provide a comprehensive protocol for testing facilities:

  • Inertia Dynamometer Protocol to Measure and Characterise Brake Emissions Using the WLTP-Brake Cycle;
  • Part 2: Minimum Requirements and Guidelines for Sampling and Measurement of Brake Emissions for Particle Number and Particle Mass;
  • Part 3: Reporting Test Results from Brake Emissions Testing.
