General Information
Frequently Asked Questions
An EU Directive is a legislative act of the European Union that sets out goals that all EU member states must achieve. However, it is up to each member state to devise their own laws on how to reach these goals through national transposition. Directives are used to harmonize laws across the EU, particularly for the functioning of the single market.
Directive 01/995 covers "Ambient air quality assessment and management for benzene, CO, ... (2nd daughter Directive of 94/62/EC Directive)". There are 2 standards associated with this directive.
Harmonized standards under 01/995 are European standards (ENs) developed by CEN, CENELEC, or ETSI in response to a mandate from the European Commission. When these standards are cited in the Official Journal of the European Union, products manufactured in conformity with them benefit from a presumption of conformity with the essential requirements of 01/995, facilitating CE marking and free movement within the European Economic Area.
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.
