ANNEXProcedure for monitoring the reference measurements for gaseous SOx emissions
For the purposes of calculating the quantities of SO2 and SO3 and acid droplets expressed as SO2 equivalent, discharged by specific installations, account must be taken of the volume of gas discharged over the duration of the specific operations in question and of the average SO2/SO3 content measured over the same period. The SO2/SO3 flow rate and content must be determined under the same temperature and humidity conditions.
