Abstract
1 Scope This document specifies a method for the determination of the airborne concentration (μg/m 3 ), mass concentration (μg/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 calculate the fraction of tyre tread in PM and concentration of tyre tread in air. These quantities are expressed on a TRWP basis, which includes the mass of tyre tread and mass of road wear encrustations, and can also be expressed on a tyre rubber polymer or tyre tread basis. Air sample collection is on quartz fibre filters with size-selective input in a range of PM 2,5 or PM 10 . The method is suitable for the determination of TRWP in indoor or outdoor atmospheres.
