M/256 - SO2, NO2, CO & 03 -ambiant air

This document specifies a continuous measurement method for the determination of the concentration of sulphur dioxide present in ambient air based on the ultraviolet fluorescence measuring principle. This document describes the performance characteristics and sets the relevant minimum criteria required to select an appropriate ultraviolet fluorescence 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 for use.
The method is applicable to the determination of the mass concentration of sulphur dioxide present in ambient air from 0 mg/m3 to 1 000 mg/m3 sulphur dioxide. This concentration range represents the certification range for the type approval test.
NOTE 1   0 mg/m3 to 1 000 mg/m3 of SO2 corresponds to 0 nmol/mol to 376 nmol/mol of SO2.
NOTE 2   Lower ranges may be used for measurement systems applied at rural locations monitoring Ecosystems.
The method covers the determination of ambient air concentrations of sulphur dioxide in zones classified as rural areas, urban-background areas and traffic-orientated locations.
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.
