適用范圍：This International Standard specifies a photometric method for the determination of the mass concentration of nitrogen oxides in exhaust gases from ducts or chimneys. NOTE —Nitrogen oxides (NOx) are practically defined as the sum of NO and NO2. The mass concentration of NOx is expressed as the equivalent NO2 concentration in milligrams per cubic metre. The method is applicable to the determination of the mass concentration of nitrogen oxides in exhaust gases from combustion processes, processes for surface treatment of metals and from organic chemical reactions, if necessary after removal by washing, in-furnace reduction and/or catalytic denitration, prior to their dispersion into the atmosphere. This International Standard is applicable to the concentration range 5 mg/m
