Stationary source emissions - Determination of the mass concentration of ammonia - Manual method (ISO 21877:2019)
This document specifies a manual method of measurement including sampling and different analytical methods for the determination of the mass concentration of ammonia (NH3) in the waste gas of industrial plants, for example combustion plants or agricultural plants. All compounds which are volatile at the sampling temperature and produce ammonium ions upon dissociation during sampling in the absorption solution are measured by this method, which gives the volatile ammonia content of the waste gas.
This document specifies an independent method of measurement, which has been validated in field tests in a NH3 concentration range of approximately 8 mg/m3 to 65 mg/m3 at standard conditions. The lower limit of the validation range was determined under operational conditions of a test plant. The measurement method can be used at lower values depending, for example, on the sampling duration, sampling volume and the limit of detection of the analytical method used.
NOTE 1 The plant, the conditions during field tests and the performance characteristics obtained in the field are given in Annex A.
This method of measurement can be used for intermittent monitoring of ammonia emissions as well as for the calibration and validation of permanently installed automated ammonia measuring systems.
NOTE 2 An independent method of measurement is called standard reference method (SRM) in EN 14181.
Emissionen aus stationären Quellen - Ermittlung der Massenkonzentration von Ammoniak - Manuelles Verfahren (ISO 21877:2019)
Dieses Dokument legt ein manuelles Messverfahren einschließlich der Probenahme und verschiedener Analyseverfahren zur Bestimmung der Massenkonzentration von Ammoniak (NH3) im Abgas von Industrieanlagen wie etwa Verbrennungsanlagen oder landwirtschaftlichen Anlagen fest. Alle Stoffe, die bei der Probenahmetemperatur flüchtig sind und bei der Zersetzung während der Probenahme in der Absorptionslösung Ammoniumionen bilden, werden mit diesem Verfahren gemessen, das daher den flüchtigen Ammoniakgehalt im Abgas bestimmt.
Dieses Dokument legt ein unabhängiges Messverfahren fest, das in Feldversuchen einem NH3 Konzentrationsbereich von ungefähr 8 mg/m3 bis 65 mg/m3 unter Normbedingungen validiert wurde. Die untere Grenze des Validierungsbereichs wurde durch die Betriebsbedingungen der untersuchten Anlage bestimmt. Das Messverfahren kann auch bei geringeren Werten in Abhängigkeit beispielsweise von der Probenahmedauer, des Probenvolumens und der Nachweisgrenze des Analyseverfahrens eingesetzt werden.
ANMERKUNG 1 Die Anlage, die Bedingungen der Feldversuche und die im Rahmen der Feldversuche ermittelten Verfahrenskenngrößen sind in Anhang A angegeben.
Dieses Messverfahren kann für die wiederkehrende Überwachung von Ammoniak-Emissionen sowie die Kalibrierung und Validierung dauerhaft eingebauter automatischer Ammoniak-Messeinrichtungen verwendet werden.
ANMERKUNG 2 Ein unabhängiges Messverfahren wird in EN 14181 als Standardreferenzverfahren (SRM, en: standard reference method) bezeichnet.
Émissions de sources fixes - Détermination de la concentration en masse de l’ammoniac dans les gaz de combustion - Méthode manuelle (ISO 21877:2019)
Le présent document spécifie une méthode manuelle de mesurage comprenant l'échantillonnage ainsi que différentes méthodes d'analyse pour la détermination de la concentration en masse de l'ammoniac (NH3) dans les effluents gazeux des installations industrielles, par exemple les installations de combustion ou les exploitations agricoles. Tous les composés volatils à la température d'échantillonnage et produisant des ions ammonium dans la solution d'absorption durant l'échantillonnage sont mesurés par cette méthode qui donne alors la teneur en ammoniac volatil des effluents gazeux.
Le présent document spécifie une méthode de mesure indépendante qui a été validée lors d'essais sur site dans une gamme de concentration en NH3 d'environ 8 mg/m3 à 65 mg/m3 dans des conditions normales. La limite inférieure de la gamme de validation a été déterminée dans les conditions opérationnelles d'une installation d'essai. La méthode de mesure peut être utilisée à des valeurs moins élevées, en fonction, par exemple, de la durée d'échantillonnage, du volume d'échantillonnage et de la limite de détection de la méthode d'analyse utilisée.
NOTE 1 L'installation, les conditions des essais sur site et les caractéristiques de performance obtenues sur le site sont indiquées à l'Annexe A.
Cette méthode de mesure peut être utilisée pour la surveillance intermittente des émissions d'ammoniac ainsi que pour l'étalonnage et la validation de systèmes de mesurage automatisés des concentrations en ammoniac.
NOTE 2 Une méthode de mesure indépendante est appelée « méthode de référence normalisée » (SRM) dans l'EN 14181.
Emisije nepremičnih virov - Določevanje masne koncentracije amoniaka - Ročna metoda (ISO 21877:2019)
Ta dokument določa ročno metodo merjenja, vključno z vzorčenjem in različnimi analitičnimi metodami, za določanje masne koncentracije amoniaka (NH3) v odpadnih plinih industrijskih obratov, na primer kurilnih naprav ali kmetijskih obratov. Po tej metodi se merijo vse spojine, ki so hlapne pri temperaturi vzorčenja in tvorijo amonijeve ione po razpadu v absorpcijski raztopini, kar daje vsebnost hlapnega amoniaka v odpadnih plinih. Ta dokument določa neodvisno metodo merjenja, ki je bila potrjena v terenskih preskusih do koncentracije NH3 približno 65 mg/m3 pri standardnih pogojih. To metodo merjenja je mogoče uporabljati za občasno spremljanje emisij amoniaka, pa tudi za umerjanje in potrjevanje stalno nameščenih avtomatiziranih merilnih sistemov za amoniak.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
