‘A. Reference methods for the assessment of concentrations of sulphur dioxide, nitrogen dioxide and oxides of nitrogen, particulate matter (PM_(10) and PM_(2,5)), lead, benzene, carbon monoxide and ozone 1. Reference method for the measurement of sulphur dioxide The reference method for the measurement of sulphur dioxide is that described in EN 14212:2012 “Ambient air — Standard method for the measurement of the concentration of sulphur dioxide by ultraviolet fluorescence”. 2. Reference method for the measurement of nitrogen dioxide and oxides of nitrogen The reference method for the measurement of nitrogen dioxide and oxides of nitrogen is that described in EN 14211:2012 “Ambient air — Standard method for the measurement of the concentration of nitrogen dioxide and nitrogen monoxide by chemiluminescence”. 3. Reference method for the sampling and measurement of lead — unchanged 4. Reference method for the sampling and measurement of PM_(10) The reference method for the sampling and measurement of PM_(10) is that described in EN12341:2014 “Ambient Air — standard gravimetric measurement method for the determination of the PM_(10) or PM_(2,5) mass concentration of suspended particulate matter”. 5. Reference method for the sampling and measurement of PM_(2,5) The reference method for the sampling and measurement of PM_(2,5) is that described in EN12341:2014 “Ambient Air — standard gravimetric measurement method for the determination of the PM_(10) or PM_(2,5) mass concentration of suspended particulate matter” 6. Reference method for the sampling and measurement of benzene — unchanged 7. Reference method for the measurement of carbon monoxide The reference method for the measurement of carbon monoxide is that described in EN 14626:2012 “Ambient air — Standard method for the measurement of the concentration of carbon monoxide by non-dispersive infrared spectroscopy”. 8. Reference method for measurement of ozone The reference method for the measurement of ozone is that described in EN 14625:2012 “Ambient air — Standard method for the measurement of the concentration of ozone by ultraviolet photometry”.’
