Abstract
What 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 evaluation of the suitability of an analyzer for use in a specific fixed site so as to meet the data quality requirements as specified in Annex I of Directive 2012/50/EC [1] and requirements during sampling, calibration and quality assurance for use. The methods described in BS EN 14625
