Ambient air. Standard method for the measurement of the concentration of ozone by ultraviolet photometry Ingestion-build-73935 This should be done with1 Scope This European Standard specifies a continuous measurement method for the determination of the concentrations of ozone present in ambient air based on the ultraviolet photometric measuring principle. This standard describes the performance characteristics and sets the relevant minimum criteria required to select an appropriate ultraviolet photometric analyser by means of type approval tests. It also includes the evaluation of the suitability of
