Scope

This European Standard specifies a continuous measurement method for the determination of the concentration of carbon monoxide present in ambient air based on the non-dispersive infrared spectroscopic measuring principle. This standard describes the performance characteristics and sets the relevant minimum criteria required to select an appropriate non-dispersive infrared spectroscopic 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 data quality requirements as specified in Annex I of Directive 2008/50/EC [1] and requirements during sampling, calibration and quality assurance for use.
The method is applicable to the determination of the mass con¬centration of carbon monoxide present in ambient air up to 100 mg/m3 carbon monoxide. This concentration range represents the certification range for CO for the type approval test.
NOTE 1 Other ranges may be used depending on the levels present in ambient air.
NOTE 2 When the standard is used for other purposes than for measurements required by Directive 2008/50/EC, the ranges and uncertainty requirements may not apply.
The method covers the determination of ambient air concentrations of carbon monoxide in areas classified as rural, urban-background and traffic-orientated and those influenced by industrial sources.
The results are expressed in mg/m3 (at 20 °C and 101,3 kPa).
NOTE 3 100 mg/m3 of CO corresponds to 86 mol/mol of CO.
This standard contains information for different groups of users.
Clauses 5 to 7 and Annexes B, C and D contain general information about the principles of carbon monoxide measurement by non-dispersive infrared spectroscopic analyser and sampling equipment.
Clause 8 and Annex E are specifically directed towards test houses and laboratories that perform type-approval testing of carbon monoxide analysers. These sections contain information about:
- Type-approval test conditions, test procedures and test requirements;
- Analyser performance requirements;
- Evaluation of the type-approval test results;
- Evaluation of the uncertainty of the measurement results of the carbon monoxide analyser based on the type-approval test results.
Clauses 9 to 11 and Annex F are directed towards monitoring networks performing the practical measurements of carbon monoxide in ambient air. These sections contain information about:
- Initial installation of the analyser in the monitoring network and acceptance testing;
- Ongoing quality assurance/quality control;
- Calculation and reporting of measurement results;
- Evaluation of the uncertainty of measurement results under practical monitoring conditions.
