Ambient air quality - Standard method for the measurement of the concentration of carbon monoxide by nondispersive infrared spectroscopy

Asnjë informacion i shtuar.

This document specifies a continuous measurement method for the determination of the concentration of carbon monoxide present in ambient air based on the non-dispersive infrared measuring principle (NDIR). This document describes the performance characteristics and sets the relevant minimum criteria required to select an appropriate non-dispersive infrared carbon monoxide analyser by means of type approval tests. It also includes the evaluation of the suitability of an anayser 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 mass concentration of carbon monoxide present in ambient air in the range from 0 mg/m3 to 100 mg/m3 carbon monoxide. This concentration range represents the certification range for the type approval test. NOTE 1 0 mg/m3 to 100 mg/m3 of CO corresponds to 0 mmol/mol to 86 mmol/mol of CO. The method covers the determination of ambient air concentrations of carbon monoxide in zones classified as rural areas, urban-background areas and traffic-orientated locations. NOTE 2 Other 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.
