AS 3580.9.8-2008

This Standard sets out a method for the continuous determination of suspended particulate matter in ambient air using a tapered element oscillating microbalance (TEOM) analyser. The method can provide a measure of mean particle concentration over periods from 10 minutes to 24 hours. The moving 10-minute mean is updated every 2 seconds, whereas the 24-hour mean mass concentration is updated every 60 minutes on the hour. Results are normally reported as 24-hour, time-integrated mean values.
