Measuring nitrogen dioxide NO₂ (chemiluminescence), DIN EN 14211

This European Standard specifies a continuous chemiluminescence measurement method for determining the concentration of nitrogen dioxide and nitric oxide in air. It specifies the performance parameters and sets out the minimum requirements for the qualification of chemiluminescence measuring instruments. It also covers the assessment of a measuring instrument’s suitability for use at a specific fixed monitoring site with regard to the data quality requirements set out in Annex I to Directive 2008/50/EC and with regard to the requirements for sampling, calibration and quality assurance.
