[Current]Methods for sampling and analysis of ambient air, Method 9.11: Determination of suspended particulate matter — PM10 beta attenuation monitors
AS/NZS 3580.9.11:2022 sets out the method for the determination of suspended particulate matter in ambient air using a beta attenuation monitor (BAM). The method can provide a measure of the time-integrated mean particle concentrations for periods ranging from 10 min to 24 h.
