Stationary source emissions - Determination of volume concentration of oxygen (O2) - Reference method - Paramagnetism

This European Standard describes the paramagnetic method, including the sampling and the gas conditioning system, to determine the oxygen concentrations in flue gases emitted to the atmosphere from ducts and stacks.
This European Standard is the Standard Reference Method (SRM) for periodic monitoring and for the calibration or control of Automatic Measuring Systems (AMS) permanently installed on a stack, for regulatory purposes or other purposes. To be used as the SRM, the user shall demonstrate that the performance characteristics of the method are better than the performance criteria defined in this European Standard and that the overall uncertainty of the method is less than ± 6,0 percent of the measured concentration.
NOTE   When paramagnetism is the measurement principle used for AMS, reference should be made to EN 14181 and other relevant standards provided by CEN/TC 264.
An alternative method to this SRM may be used provided that the user can demonstrate equivalence according to the Technical Specification CEN/TS 14793, to the satisfaction of his national accreditation body or law.
This Standard Reference Method has been evaluated during field tests on waste incineration, co-incineration and large combustion installations. It has been validated for sampling periods of 30 min in the range: 5 percent to 26 percent. Oxygen concentration values, expressed in percent volume, are used in order to allow emission measurements of pollutants to be standardised to the reference O2 concentration and dry gas conditions required by the following Council Directives:
   Council Directive 2001/80/EC on the limitation of emissions of certain pollutants into the air from large combustion plants;
   Council Directive 2000/76/EC on waste incineration plants.

Emissionen aus stationären Quellen - Bestimmung der Volumenkonzentration von Sauerstoff (O2) - Referenzverfahren - Paramagnetismus

Diese Europäische Norm beschreibt das paramagnetische Verfahren einschließlich der Probenahme und des Gasvorbehandlungssystems zur Bestimmung der Sauerstoffkonzentrationen in Abgasen, die aus Abgaskanälen in die Atmosphäre emittiert werden.
Diese Europäische Norm ist das Standardreferenzverfahren (SRM) für die periodische Überwachung und für die Kalibrierung oder Überprüfung von automatischen Messsystemen (AMS), die aus gesetzgeberischen oder anderen Gründen permanent an einem Abgaskanal installiert sind. Damit dieses Verfahren als Standardreferenzverfahren angewandt werden kann, muss der Anwender nachweisen, dass die Verfahrenskenngrößen besser sind als die Leistungskriterien in dieser Norm und dass die Gesamtmessunsicherheit des Verfahrens kleiner ist als ± 6 % der gemessenen Konzentration.
ANMERKUNG   Wenn der Paramagnetismus als Messprinzip eines automatischen Messsystems genutzt wird, sollte auf EN 14181 und andere einschlägige Normen des CEN/TC 264 Bezug genommen werden.
Ein anderes als dieses Standardreferenzverfahren darf angewendet werden, wenn der Anwender vor der nationalen Akkreditierungsstelle oder dem Gesetz die Äquivalenz nach der Technischen Spezifikation CEN/TS 14793 nachweisen kann.
Dieses Standardreferenzverfahren wurde während Feldversuchen an Abfallverbrennungsanlagen und Mitverbrennungsanlagen sowie an Großfeuerungsanlagen erprobt. Sie wurde mit Probenahmedauern von 30 min im Bereich von 5 % bis 26 % validiert. O2-Konzentrationswerte, angegeben als Volumenanteil, werden verwendet, um die Ergebnisse von Emissionsmessungen von Schadstoffen auf die O2-Bezugskonzentration und auf trockenes Gas zu beziehen, wie von den folgenden Richtlinien des Rates gefordert wird:
-   Richtlinie 2001/80/EG des Europäischen Parlaments und des Rates vom 23. Oktober 2001 zur Begrenzung von Schadstoffemissionen von Großfeuerungsanlagen in die Luft;
Richtlinie 2000/76/EG des Europäischen Parlaments und des Rates vom 4. Dezember 2000 über die Verbrennung von Abfällen.

Emissions de sources fixes - Détermination de la concentration volumique en oxygène (O2) - Méthode de référence: Paramagnétisme

La présente Norme européenne décrit la méthode paramagnétique comprenant le système de prélèvement et
de conditionnement du gaz, afin de déterminer les concentrations en oxygène présentes dans les effluents
gazeux émis dans l’atmosphère par les conduits et cheminées.
La présente Norme européenne est la méthode de référence normalisée (SRM) en matière de surveillance
périodique et d’étalonnage ou de contrôle des systèmes automatiques de mesurage (AMS) installés à
demeure sur une cheminée, à des fins réglementaires ou autres. Pour utiliser la norme comme SRM,
l’utilisateur doit démontrer que les caractéristiques de performance de la méthode sont meilleures que les
critères de performance définis dans la présente Norme européenne et que l’incertitude globale de la
méthode est inférieure à ± 6,0 % de la concentration mesurée.
NOTE Lorsque le paramagnétisme est utilisé comme principe de mesurage pour l’AMS, consulter l’EN 14181 et les
autres normes pertinentes élaborées par le CEN/TC 264.
Il est possible d’employer une méthode différente à condition que l’utilisateur puisse démontrer son
équivalence selon la spécification technique de la CEN/TS 14793 et en accord avec son organisme
d’accréditation national ou la loi.
Cette méthode de référence normalisée a été évaluée au cours d’essais sur site pratiqués sur les installations
destinées à l’incinération des déchets, la coincinération et sur des grandes installations de combustion. Elle a
été validée pour des périodes de prélèvement de 30 min dans la plage comprise entre : 5 % et 26 %. Les
valeurs de concentration en oxygène, exprimées en pourcentage volumique, sont utilisées afin d’exprimer les
résultats des mesurages d’émission des polluants aux conditions de référence en O 2 et aux conditions de gaz
sec requises par les Directives du Conseil suivantes :

characteristics of the method are better than the performance criteria defined in this European Standard and
that the overall uncertainty of the method is less than ± 6,0 % of the measured concentration.
NOTE When paramagnetism is the measurement principle used for AMS, reference should be made to EN 14181
and other relevant standards provided by CEN/TC 264.
An alternative method to this SRM may be used provided that the user can demonstrate equivalence
according to the Technical Specification CEN/TS 14793, to the satisfaction of his national accreditation body
or law.
This Standard Reference Method has been evaluated during field tests on waste incineration, co-incineration
and large combustion installations. It has been validated for sampling periods of 30 min in the range: 5 % to
26 %. Oxygen concentration values, expressed in % volume, are used in order to allow emission
measurements of pollutants to be standardised to the reference O concentration and dry gas conditions
required by the following Council Directives:
