scope:
This European Standard describes the chemiluminescence method, including the sampling and the gas conditioning system, to determine the NO/NO2/NOx concentrations in flue gases emitted from ducts and stacks to atmosphere. This European Standard is the Standard Reference Method (SRM) for periodic monitoring and for calibration or control of Automatic Measuring Systems (AMS) permanently installed on a stack, for regulatory or other purposes such as calibration. To be used as the SRM, the user shall demonstrate that the performance characteristics of the method are better than the performance criteria defined in this European Standard and that the overall uncertainty of the method is less than ± 10 % relative at the daily Emission Limit Value (ELV). NOTE When the chemiluminescence method
