标准摘要
ISO 15337:2009 specifies the gas phase titration (GPT) method for the calibration of ambient air ozone (O 3 ) analysers. The method is applicable to the calibration of O 3 concentrations in the range 10 µg m −3 (5 nmol mol −1 mole fraction) to 2 000 µg m −3 (1 000 nmol mol −1 mole fraction). ISO 15337:2009 uses the reference conditions of 25 °C and 101,325 kPa; however, reference temperatures of 0 °C and 20 °C are also acceptable.
