Ambient air - Standard method for the measurement of the concentration of sulphur dioxide by ultraviolet fluorescence

This document specifies a continuous measurement method for the determination of the concentration of sulfur 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 testing. 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 concentration of sulphur dioxide present in ambient air up to 1000 µg/m3. This concentration range represents the certification range for sulfur dioxide for type testing. NOTE 1 It is possible to use other ranges depending on the levels present in ambient air. NOTE 2 When this document is used for purposes other than for measurements required by Directive 2008/50/EC, the ranges and uncertainty requirements possibly do not apply. The method covers the determination of ambient air concentrations of sulfur dioxide in locations classified as rural areas, urban-background areas, and for sampling influenced by traffic or industrial sources. The results are expressed in µg/m3 (at 20 °C and 101,3 kPa). NOTE 3 1 000 µg/m3 of SO2 corresponds to 376 nmol/mol of SO2. This document contains information for different groups of users. Clause 5 to Clause 7 and Annex C and Annex D contain general information about the principles of sulfur dioxide measurement by ultraviolet fluorescence analyser and sampling equipment. Clause 8 and Annex E are specifically directed towards test houses and laboratories that perform type testing of sulfur dioxide analysers. These sections contain information about: — type testing conditions, test procedures and test requirements; — analyser performance requirements; — evaluation of the type testing results; — evaluation of the uncertainty of the measurement results of the sulfur dioxide analyser based on the type testing results. Clause 9 to Clause 11 and Annex F and Annex G are directed towards monitoring networks performing the practical measurements of sulfur dioxide 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 the measurement results under practical monitoring conditions. This document represents an evolution of earlier editions (EN 14212:2005 and EN 14212:2012). It is advisable that when equipment is procured it complies fully with this document. NOTE 4 Type testing performed prior to the publication of this document for the purpose of demonstrating equivalence are still valid. NOTE 5 Analysers type tested prior to the publication of this document remain valid for use for regulated monitoring purposes.

Instrumental Odour Monitoring Systems (IOMS) - Part 1: Definitions and general aspects

This document specifies: — definitions of specific terms used in this series of documents; — general aspects of IOMS design and management; — contexts of application where the use of IOMS is examined in this series of documents; — minimal documentation for the management of an IOMS. This document covers definitions and general aspects relating to instrumental odour monitoring in: 1) ambient air; 2) ambient air at the fence line of the source installation; 3) odorous gas emissions, including waste gases upstream of odorant abatement devices. This document does not apply to definitions and general aspects relating to: a) determination of the odour concentration in ouE/m3, for which the reference method is specified in EN 13725. This document is not aimed at demonstrating equivalence between the determination of olfactory stimulus quantity using an IOMS and the method described in EN 13725 and letting an IOMS to implement an alternative method to EN 13725; b) monitoring of hedonic tone (or pleasantness or unpleasantness); c) monitoring of odour annoyance; d) health and safety air monitoring.
