BS EN 1747 12 specifies a chemiluminescence method for the determination of the mass concentration of ozone in ambient air. The method described in BS EN 1747 12 is applicable to the determination of the mass concentration of ozone between 2 4g m3 [0,001 ppm(V V)] and 10 mg m3 [5 ppm(V V)] at the reference conditions of 25 C and 101,3 kPa. Ultraviolet (UV) photometry is specified as
