Scope

This Standard specifies the non-dispersive infrared absorption method that is
to determine the sulphur dioxide from organized exhausted gas of stationary
source.
This Standard is applicable to instantaneous monitoring and continuous
monitoring on sulphur dioxide from organized exhausted gas of stationary
source. The detection limit of this method is 3 mg/m3; the lower limit of
determination is 10 mg/m3.
