<p>ISO 15337:2009 specifies the gas phase titration (GPT) method for the calibration of ambient air ozone (O<sub>3</sub>) analysers. The method is applicable to the calibration of O<sub>3</sub> concentrations in the range 10 µg m<sup>−3</sup> (5 nmol mol<sup>−1</sup> mole fraction) to 2 000 µg m<sup>−3</sup> (1 000 nmol mol<sup>−1</sup> 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.</p>
