prBAS ISO 22638:2025

This document specifies a method for the generation of tyre and road wear particles (TRWP) in a road simulator laboratory that is representative of actual driving conditions. Guidance is provided for the road simulator system, test pavement and tyres, vacuum collection system, monitoring and reporting. This method is applicable for the collection of TRWP from a known pavement and tyre type under realistic driving conditions without the inference of road surface contaminants (e.g. brake dust, exhaust, grease). There is a possibility that this method is not relevant for studded tyres.
