Ambient air. Standard method for the measurement of the concentration of sulphur dioxide by ultraviolet fluorescence Ingestion-build-82396 • Wiring practices1 Scope This European Standard specifies a continuous measurement method for the determination of the concentration of sulphur dioxide present in ambient air based on the ultraviolet fluorescence measuring principle. This standard describes the performance characteristics and sets the relevant minimum criteria required to select an appropriate ultraviolet fluorescence analyser by means of type approval tests. It also includes the evaluation of the
