Ambient air. Standard method for the measurement of the concentration of ozone by ultraviolet photometry Ingestion-build-239834 This part of ISO 12164What is BS EN 14625 Ambient air about ? BS EN 14625 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 analyzer by means of type approval tests. BS EN 14625 also includes the
