Ambient air quality - 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 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.
Luftqualität - Messverfahren zur Bestimmung der Konzentration von Schwefeldioxid mit Ultraviolett-Fluoreszenz
Dieses Dokument legt ein kontinuierliches Messverfahren zur Bestimmung der Konzentration von Schwefeldioxid in Luft nach dem Ultraviolett-Fluoreszenz-Messprinzip fest. Dieses Dokument gibt die Leistungskenngrößen an und legt die relevanten Mindestanforderungen für die Eignungsprüfung von Ultraviolett-Fluoreszenz-Messgeräten fest. Es schließt auch die Bewertung der Eignung eines Messgeräts zur Anwendung an einer spezifischen Messstelle im Hinblick auf die Datenqualitätsanforderungen der EU-Richtlinien ein und enthält Anforderungen für die Probenahme, Kalibrierung und Qualitätssicherung bei der Anwendung.
Das Verfahren ist anwendbar zur Bestimmung der Massenkonzentration von Schwefeldioxid in Luft im Bereich von 0 µg/m³ bis 1000 µg/m³. Dieser Konzentrationsbereich entspricht dem Zertifizierungsbereich für die Eignungsprüfung.
ANMERKUNG 1 0 µg/m³ bis 1000 µg/m³ SO2 entspricht 0 nmol/mol bis 376 nmol/mol SO2.
ANMERKUNG 2 Kleinere Bereiche können für Messsysteme an ländlichen Standorten zur Überwachung von Ökosystemen verwendet werden.
Das Verfahren umfasst die Bestimmung der Konzentration von Schwefeldioxid in Gebieten, die als ländliche Gebiete, Gebiete mit städtischem Hintergrund und verkehrsbezogene Standorte klassifiziert sind.
Die Ergebnisse werden in µg/m³ (bei 293 K und 101,3 kPa) angegeben.
Wenn diese Norm für andere als in der EU-Richtlinie festgelegte Zwecke eingesetzt wird, müssen die Anforderungen hinsichtlich Anwendungsbereich und Unsicherheit nicht gestellt werden.
Qualité de l'air ambiant - Méthode normalisée pour le mesurage de la concentration de soufre par fluorescence U.V.
Le présent document spécifie une méthode de mesurage en continu pour la détermination de la concentration en dioxyde de soufre (SO2) dans l'air ambiant, selon le principe de mesure par fluorescence U.V. Le présent document décrit les caractéristiques de performance et fixe les critères minimums requis pour sélectionner un analyseur par fluorescence U.V. à l'aide d'essais d'approbation de type. Il présente également l'évaluation de l'aptitude à l'emploi d'un analyseur sur un site fixe spécifique de manière à répondre aux exigences de qualité des données prescrites dans les Directives ainsi qu'aux exigences à observer au cours du prélèvement, de l'étalonnage et de l'assurance qualité.
La méthode s'applique à la détermination de la concentration massique en SO2 présent dans l'air ambiant dans une plage de concentration en SO2 comprise entre 0 mg/m3 et 1 000 mg/m3. Cette plage de concentration représente l'étendue de mesure certifiée pour l'essai d'approbation de type.
NOTE 1 La plage comprise entre 0 mg/m3 et 1 000 mg/m3 de SO2 correspond à la plage de 0 nmol/mol à 376 nmol/mol de SO2.
NOTE 2 Des plages inférieures peuvent être utilisées pour les systèmes de mesure appliqués aux zones rurales contrôlant des écosystèmes.
La méthode couvre la détermination des concentrations en SO2 présent dans l'air ambiant dans les zones classées comme zones rurales, périurbaines et proches d'axes de circulation automobile.
Les résultats sont exprimés en mg/m3 (à 293 K et 101,3 kPa).
Lorsque la norme est utilisée à d'autres fins que la Directive UE, les exigences relatives à la plage et à l'incertitude peuvent ne pas être appliquées.
