The quantification of variability and effects from testing different brakes at different facilities is a critical input to the rollout of a protocol from the World Forum for Harmonization of Vehicle Regulations to characterize brake emissions using inertia dynamometers. Having 17 laboratories from around the world testing five different brake corners is a reliable manner to quantify the sensitivity and ruggedness of the PMP protocol. The first part of the paper presents an overview of the structure of the ILS and the different brake corners under testing. The second part presents a taxonomy and high-level description of the dynamometer facilities related to enclosure style, constant volume sampling system, and instrumentation for measuring particulate mass (PM) and particle number (PN). The high-level results combined with the lessons learned (from the perspective of actual results, project execution, and project integration) will conform a basis for enhancing and detailing as needed the upcoming protocol from the PMP for vehicles categories M1 and N1. All combined will enable results to repeat and compare across different brakes, friction materials, and testing facilities.
