Scope

This Standard specifies the fixed potential by electrolysis method for determination of
nitrogen oxides in stationary source emission.
This Standard is applicable to the determination of nitrogen oxide in the stationary
source emission.
The detection limit of tis Standard method is 3mg/m3 for nitrogen oxide (calculated by
NO2); 3mg/m3 for nitrogen dioxide; lower limit of determination is 12mg/m3 for nitrogen
oxide (calculated by NO2); 12mg/m3 for nitrogen dioxide.
