Ambient air quality. Standard method for the measurement ofthe concentration of nitrogen dioxide and nitrogen monoxide bychemiluminescence

Alkalmazási terület

This document specifies a continuous measurement method for the determination of the concentration of nitrogen dioxide and nitrogen monoxide present in ambient air based on the chemiluminescence measuring principle. This document describes the performance characteristics and sets the relevant minimum criteria required to select an appropriate chemiluminescence analyser by means of type approval tests. It also includes the evaluation of the suitability of an analyser for use in a specific fixed site so as to meet the Directives data quality requirements and requirements during sampling, calibration and quality assurance. The method is applicable to the determination of the concentration of nitrogen dioxide present in ambient air from 0 mg/m3 to 500 mg/m3. This concentration range represents the certification range for NO2 for the type approval test. NOTE 1 0 mg/m3 to 500 mg/m3 of NO2 corresponds to 0 nmol/mol to 261 nmol/mol of NO2. The method is applicable to the determination of the concentration of nitrogen monoxide present in ambient air from 0 mg/m3 to 1 200 mg/m3. This concentration range represents the certification range for NO for the type approval test. NOTE 2 0 mg/m3 to 1 200 mg/m3 of NO corresponds to 0 nmol/mol to 962 nmol/mol of NO. The method covers the determination of ambient air concentrations of nitrogen dioxide and nitrogen monoxide in zones classified as rural areas, urban-background areas and traffic-orientated locations. NOTE 3 Lower ranges may be used for measurement systems applied at rural locations monitoring Ecosystems. The results are expressed in mg/m3 (at 293 K and 101,3 kPa). When the standard is used for other purposes than the EU Directive, the range and uncertainty requirements need not apply.
