This standard specifies the non-dispersive infrared absorption method for the determination of nitrogen oxides in exhaust gases from fixed pollution sources. This standard is applicable to the determination of nitrogen oxides in exhaust gas from fixed pollution sources. The detection limit of nitric oxide (measured as NO) in this method is 3 mg/m, and the lower limit of determination is 12 mg/m.
