This International Standard describes an ultraviolet fluorescence method for sampling and determining sulfur dioxide (SO2) concentrations in the ambient air using automatic analysers. This International Standard is applicable to the determination of sulfur dioxide mass concentrations of a few micrograms per cubic metre to a few milligrams per cubic metre or, expressed in terms of volume fraction, from a few microlitres per cubic metre to a few millilitres per cubic metre.
