Scope

This standard specifies the chemiluminescence method for automatically measuring ozone in ambient air. This standard is applicable to the automatic measurement of ozone in ambient air. When the instrument's measurement range is 0 nmol/mol to 500 nmol/mol, the detection limit of this method under reference conditions (298.15 K, 101.325 kPa) is 4 μg/m3, and the measurement limit is 16 μg/m3.
