scope:
This Standard sets out a method for the continuous determination of PM2.5 particulate matter in ambient air using a tapered element oscillating microbalance (TEOM) monitor incorporating a filter dynamic measurement system (FDMS) unit. The method can provide a measure of average particle concentration over periods from 1 hour to 24 hours. The rolling 1-hour average is updated every 6 minutes, whereas the rolling 24-hour average mass concentration is updated every 60 minutes on the hour. Results are normally reported as 24-hour, time-integrated average values.
