Ambient air. Determination of the mass concentration of tire and road wear particles (TRWP). Pyrolysis-GC-MS method1 Scope This document specifies a method for the determination of the airborne concentration (g m3), mass concentration (g g) and mass fraction (%) of tyre and road wear particles (TRWP) in ambient particulate matter (PM) samples. This document establishes principles for air sample collection, the generation of pyrolysis fragments from the sample, and the quantification of the generated polymer fragments. The quantified polymer mass is used to
