Today non-exhaust particulate matter emissions, the abrasion of brakes, tires and the road itself, as well as resuspension of road dust, already have a significant share of up to 86% of all road traffic emissions. The UNECE's Particle Measurement Pro-gram is currently elaborating a planned test procedure for the regulation of brake-wear particle emissions. This paper covers the latest state of knowledge of brake wear emissions discussing their origins, physical properties and health effects. Fur-ther insights into the challenges in sampling, detection and characterization that need to be addressed to allow for a standardized, robust and reproducible brake-wear par-ticle measurement, are given. Finally, the methodology is reviewed with respect of its potential to represent real-world emission behaviour and the potential and challenges for on-board measurements.
