scope:

NEN-EN 12341 describes a standard method for determining the PM10 or PM2,5 mass concentrations of suspended particulate matter in ambient air by sampling the particulate matter on filters and weighing them by means of a balance. Measurements are performed with samplers with inlet designs as specified in Annex A, operating at a nominal flow rate of 2,3 m3/h, over a nominal sampling period of 24 h. Measurement results are expressed in μg/m3, where the volume of air is the volume at ambient conditions near the inlet at the time of sampling. The range of application of this European Standard is from approximately 1 μg/m3 (i.e. the limit of detection of the standard measurement method expressed as its uncertainty) up to 150 μg/m3 for PM10 and 120 μg/m3 for PM2,5. This European Standard describes procedures and gives requirements for the use of so-called sequential samplers, equipped with a filter changer, suitable for extended stand-alone operation. Sequential samplers are commonly used throughout the European Union for the measurement of concentrations in ambient air of PM10 or PM2,5. However, this European Standard does not exclude the use of single-filter samplers.
