This International Standard specifies a method for sampling, sample conditioning and determining dinitrogen monoxide (N2O) content in the flue gas emitted from ducts and stacks to atmosphere. It describes the non- dispersive infrared (NDIR) analytical technique, including the sampling system and sample gas conditioning system. This ISO standard is considered as a reference method for periodic monitoring and for calibration, adjustment or control of automatic monitoring systems permanently installed on a stack.This reference method has been evaluated based on a field test on sewage sludge incineration. It has been validated for N2O concentrations in the range of 0 mg/m<(hoch)3> to 400 mg/m<(hoch)3>.
