This standard specifies a gravimetric method for the determination of PM and PM in ambient air. This standard is applicable to the manual determination of PM and PM concentrations in ambient air. The detection limit of this standard is 0.010mg/m (based on an analytical balance with a sensitivity of 0.1mg, a sample load of 1.0mg, and a 108m air sample collected).
