EN 14907:2005 Ambient air quality Standard gravimetric measurement method for the determination of the PM2,5 mass fraction of suspended particulate matter
This European Standard describes a standard method for determining the PM2,5 mass concentration of suspended particulate matter in ambient air by sampling the particulate matter on filters and weighing them by means of a balance.Measurements are made over a sampling period of about 24 h, and in line with the Directive, are expressed as 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 the standard is from 1 μg/m3 (i.e. the limit of detection of the standard measurement method expressed as its uncertainty) up to 120 μg/m3 (i.e. the maximum concentration level observed during
