This standard specifies the calibration conditions, calibration items and calibration methods of portable volatile organic compound hydrogen flame ionization analyzers, and the uncertainty assessment of calibration results. This standard is applicable to the calibration of instruments with a calibration range of carbon mass concentration of 1000 mg/m3 (the unit of non-methane total hydrocarbons is measured in carbon) and a calibration range of characteristic pollutants of 50 μmol/mol. Instruments with other measurement ranges shall refer to this standard.
