摘要：Directive 2008/50/EC on ambient air quality and cleaner air for Europe sets limit values for particulate matter PM10 and PM2.5. The reference measurement methods have already been standardized (EN12341:2014), but they are manual/semi-automated methods. A standard for automated PM measurements (Article 32.3) is still missing. For that purpose, the European Commission (EC) charged the European Committee for Standardization (CEN/TC264/WG15) to elaborate a new standard for the automated measurement of Particulate Matter (PM). In the current study two different research groups tested PM automated instruments in order to check if the test criteria, listed in the draft Technical Specification CEN/TS 16450:2013, were suitable for incorporation into the draft standard. As the new standard would rely on a comparison to the reference method (RM), parallel measurements, according to EN 12341:2014, were performed during the testing period (warm and cold) using three different filter types. The results show that TEOM-FDMS overestimated PM10 at both types of environment while it passed the equivalence test when it compared to RM, for both the warm and cold period. The BAM 1020 generally agrees with the reference method that is operated with EN12341:2014 style heads and with Emfab filters. There is one data point for which the BAM significantly underestimates the reference method. The type of filters that were used (Emfab, PTFE) filters and preconditioned Whatman QMA, appeared to be very well correlated between each other for both warm and cold periods.
