Air quality. Determination of the PM10 fraction of suspended particulate matter. Reference method and field test procedure to demonstrate reference equivalence of measurement methods (British Standard)
This standard specifies the performance of PM10 sampling instruments in order to harmonize the monitoring within the framework of the European Union Council Directive 96/62/EC (2) on ambient air quality assessment and management, and the first daughter directive. In the daughter directive, by convention the ISO thoracic sampling convention has been assimilated to the PM10 fraction (see annex A; (3)).
