Stationary source emissions. Determination of PM10/PM2,5 mass concentration in flue gas. Measurement at low concentrations by use of impactors1 Scope This International Standard specifies a standard reference method for the determination of PM10 and PM2,5 mass concentrations at stationary emission sources by use of two stage impactors. The measurement method is especially suitable for measurements of mass concentrations below 40 mg m3 as half hourly averages in standard conditions (273 K, 1 013 hPa, dry gas). It is an acceptable method for the measurement in the flue gas of different
