Ambient air quality - Standard method for the measurement of the concentration of nitrogen dioxide and nitrogen monoxide by chemiluminescence

This document specifies a continuous measurement method for the determination of the concentration of nitrogen dioxide and nitrogen monoxide present in ambient air based on the chemiluminescence measuring principle. This document describes the performance characteristics and sets the relevant minimum criteria required to select an appropriate chemiluminescence 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 Directives data quality requirements and requirements during sampling, calibration and quality assurance.
The method is applicable to the determination of the concentration of nitrogen dioxide present in ambient air from 0 mg/m3 to 500 mg/m3. This concentration range represents the certification range for NO2 for the type approval test.
NOTE 1   0 mg/m3 to 500 mg/m3 of NO2 corresponds to 0 nmol/mol to 261 nmol/mol of NO2.
The method is applicable to the determination of the concentration of nitrogen monoxide present in ambient air from 0 mg/m3 to 1 200 mg/m3. This concentration range represents the certification range for NO for the type approval test.
NOTE 2   0 mg/m3 to 1 200 mg/m3 of NO corresponds to 0 nmol/mol to 962 nmol/mol of NO.
The method covers the determination of ambient air concentrations of nitrogen dioxide and nitrogen monoxide in zones classified as rural areas, urban-background areas and traffic-orientated locations.
NOTE 3   Lower 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.

Luftqualität - Messverfahren zur Bestimmung der Konzentration von Stickstoffdioxid und Stickstoffmonoxid mit Chemilumineszenz

Dieses Dokument legt ein kontinuierliches Messverfahren zur Bestimmung der Konzentration von Stickstoffdioxid und Stickstoffmonoxid in Luft nach dem Chemilumineszenz-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 Daten-qualitätsanforderungen 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 Stickstoffdioxid in Luft im Bereich von 0 µg/m³ bis 500 µg/m³. Dieser Konzentrationsbereich entspricht dem Zertifizierungsbereich für die Eignungsprüfung.
ANMERKUNG 1   0 mg/m3 bis 500 mg/m3 an NO2 entsprechen 0 nmol/mol bis 261 nmol/mol an NO2.
Das Verfahren ist anwendbar zur Bestimmung der Massenkonzentration von Stickstoffmonoxid in Luft im Bereich von 0 µg/m³ bis 1200 µg/m³. Dieser Konzentrationsbereich entspricht dem Zertifizierungsbereich für die Eignungsprüfung.
ANMERKUNG 2   0 mg/m3 bis 1 200 mg/m3 an NO entsprechen 0 nmol/mol bis 962 nmol/mol an NO.
Das Verfahren umfasst die Bestimmung der Konzentration von Stickstoffdioxid und Stickstoffmonoxid in Gebieten, die als ländliche Gebiete, Gebiete mit städtischem Hintergrund und verkehrsbezogene Standorte klassifiziert sind.
ANMERKUNG 3   Kleinere Bereiche können für Messsysteme an ländlichen Standorten zur Überwachung von Ökosystemen verwendet werden.
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.

Le présent document spécifie une méthode de mesurage en continu pour la détermination de la concentration en dioxyde d'azote et en monoxyde d'azote dans l'air ambiant, selon le principe de mesure par chimiluminescence. Le présent document décrit les caractéristiques de performance et fixe les critères minimums requis pour sélectionner un analyseur par chimiluminescence approprié 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 en dioxyde d'azote présent dans l'air ambiant dans une plage comprise entre 0 mg/m3 et 500 mg/m3. Cette plage de concentration représente l'étendue de mesure certifiée de NO2 pour l'essai d'approbation de type.
NOTE 1   La plage comprise entre 0 mg/m3 et 500 mg/m3 de NO2 correspond à la plage de 0 nmol/mol à 261 nmol/mol de NO2.
La méthode s'applique à la détermination de la concentration en monoxyde d'azote présent dans l'air ambiant dans une plage comprise entre 0 mg/m3 et 1 200 mg/m3. Cette plage de concentration représente l'étendue de mesure certifiée de NO pour l'essai d'approbation de type.
NOTE 2   La plage comprise entre 0 mg/m3 et 1 200 mg/m3 de NO correspond à la plage de 0 nmol/mol à 962 nmol/mol de NO.
La méthode couvre la détermination des concentrations en dioxyde d'azote et en monoxyde d'azote présents dans l'air ambiant dans les zones classées comme zones rurales, périurbaines et proches d'axes de circulation automobile.
NOTE 3   Des plages inférieures peuvent être utilisées pour les systèmes de mesure appliqués aux zones rurales contrôlant des écosystèmes.
Les résultats sont exprimés en mg/m3 (à 293 K et 101,3 kPa).
