(Main)Stationary source emissions - Determination of mass concentration of sulphur oxides - Standard reference method
Stationary source emissions - Determination of mass concentration of sulphur oxides - Standard reference method
This European Standard specifies the standard reference method (SRM) for the determination of the sulphuric oxide SO2 in flue gases emitted to the atmosphere from ducts and stacks. It is based on a sampling system and two analytical principles: ion chromatography and the Thorin method.
This European Standard specifies the performance characteristics to be determined and the performance criteria to be fulfilled by measuring systems based on the measurement method. It applies to periodic monitoring and to the calibration or control of automatic measuring systems (AMS) permanently installed on a stack, for regulatory or other purposes.
This European Standard specifies criteria for demonstration of equivalence of an alternative method to the SRM by application of prEN 14793.
This European Standard 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 of 0,5 mg/m³ to 2 000 mg/m³ of SO2 for an ion-chromatography variant and 5 mg/m³ to 2 000 mg/m³ of SO2 for the Thorin method according to emission limit values laid down in the Directive 2010/75/EC.
The limit values of EU Directives are expressed in units of mg/m³ of SO2 on dry basis and at standard conditions of 273 K and 101,3 kPa.
NOTE The characteristics of installations, the conditions during field tests and the values of repeatability and reproducibility in the field are given in Annex E.
Emissionen aus stationären Quellen - Bestimmung der Massenkonzentration von Schwefeloxiden - Standardreferenzverfahren
Diese Europäische Norm legt das Standardreferenzverfahren (SRM) zur Bestimmung des SO2-Gehalts in Abgasen, die aus Abgaskanälen in die Atmosphäre emittiert werden, fest. Es basiert auf einer Probenahmeeinrichtung und zwei analytischen Verfahren: die Ionenchromatographie und das Thorin-Verfahren.
Diese Europäische Norm legt zu bestimmende Verfahrenskenngrößen und Mindestanforderungen fest, die von Messeinrichtungen auf Basis dieses Messverfahrens eingehalten werden müssen. Sie gilt für wiederkehrende Messungen und für die Kalibrierung oder Überprüfung von automatischen Messeinrichtungen (AMS), die aus gesetzgeberischen oder anderen Gründen stationär an einem Abgaskanal installiert sind.
Diese Europäische Norm legt Anforderungen zum Nachweis der Gleichwertigkeit von Alternativverfahren (AM) mit dem Standardreferenzverfahren (SRM) durch Anwendung der prEN 14793 fest.
Diese Europäische Norm wurde in Feldversuchen an Abfallverbrennungsanlagen, Mitverbrennungsanlagen und Großfeuerungsanlagen validiert. Sie wurde mit Probenahmedauern von 30 min im Bereich von 0,5 mg/m3 bis 2 000 mg/m3 SO2 mit der ionenchromatographischen Variante und von 5 mg/m3 bis 2 000 mg/m3 SO2 für das Thorin-Verfahren validiert, entsprechend den in der Richtlinie 2010/75/EU festgelegten Emissionsgrenzwerten.
In den EU-Richtlinien werden die Grenzwerte ausgedrückt in Milligramm SO2 je Kubikmeter in trockenem Gas und bei Normbedingungen von 273 K und 101,3 kPa.
ANMERKUNG Die Einzelheiten der Anlagen, die Bedingungen bei den Feldversuchen und die Werte der Wiederhol- und der Vergleichpräzision im Feld werden in Anhang E aufgeführt.
Emissions de sources fixes - Détermination de la concentration massique des oxydes de soufre - Méthode de référence normalisée
La présente Norme européenne spécifie la méthode de référence normalisée (SRM) pour la détermination du dioxyde de soufre SO2 dans les effluents gazeux émis dans l'atmosphère par les conduits et cheminées. Elle est basée sur un système de prélèvement et deux principes d'analyse : la chromatographie d'échange d'ions et la méthode au Thorin.
La présente Norme européenne spécifie les caractéristiques de performance devant être déterminées et les critères de performance devant être remplis par les systèmes de mesurage fondés sur cette méthode de mesurage. Elle s'applique à la surveillance périodique et à l'étalonnage ou au contrôle des systèmes de mesurage automatisés (AMS, Automatic Measuring Systems) installés à demeure sur une cheminée, à des fins réglementaires ou à d'autres fins.
La présente Norme européenne spécifie les critères permettant de démontrer l'équivalence d'une méthode « alternative » à la méthode de référence normalisée par l'application du prEN 14793.
La présente Norme européenne a été évaluée au cours d’essais sur site pratiqués sur les installations destinées à l’incinération des déchets, à la coincinération et sur des grandes installations de combustion. Elle a été validée pour des périodes de prélèvement de 30 min, dans la gamme de 0,5 mg/m3 à 2 000 mg/m3 de SO2 pour la chromatographie d'échange d'ions et de 5 mg/m3 à 2 000 mg/m3 of SO2 pour la méthode au Thorin, conformément aux valeurs limites d'émission spécifiées dans la Directive 2010/75/CE.
Les valeurs limites des directives UE sont exprimées en mg/m3 de SO2, sur gaz secs et dans les conditions normales de 273 K et 101,3 kPa.
NOTE Les caractéristiques des installations, les conditions des essais sur site et les valeurs de répétabilité et de reproductibilité sur site sont indiquées à l'Annexe E.
Emisije nepremičnih virov - Določevanje masne koncentracije žveplovih oksidov - Standardna referenčna metoda
Ta evropski standard določa standardno referenčno metodo (SRM) za določanje žveplovega dioksida SO2 v dimnih plinih, ki prehajajo v ozračje iz vodov in odvodnikov. Temelji na sistemu vzorčenja in dveh analitičnih metodah: ionski kromatografiji in Thorinovi metodi.
Ta evropski standard določa lastnosti zmogljivosti in merila zmogljivosti, ki jih morajo izpolnjevati merilni sistemi na podlagi te merilne metode. Uporablja se za redno spremljanje in umerjanje ali nadzor avtomatskih merilnih sistemov (AMS), ki so trajno nameščeni na odvodnik, in sicer za zakonske ter druge namene.
Ta evropski standard določa merila za prikaz enakovrednosti alternativne metode standardni referenčni metodi z uporabo standarda prEN 14793.
Ta evropski standard je bil ocenjen med preskusi sežiganja odpadkov, sosežiga in velikih kurilnih naprav na terenu. Potrjen je bil za 30-minutna obdobja vzorčenja v razponu 0,5–2000 mg/m³ SO2 za različico z ionsko kromatografijo in 5–2000 mg/m³ SO2 za Thorinovo metodo v skladu z mejnimi vrednostmi emisij, opredeljenimi v Direktivi 2010/75/ES.
Mejne vrednosti direktiv EU so izražene v mg/m³ SO2 na suhi osnovi in pri standardnih pogojih 273 K in 101,3 kPa.
OPOMBA: Lastnosti naprav, pogoji med preskusi na terenu ter vrednosti ponovljivosti in reprodukcije na terenu so podani v dodatku A.
