Stationary source emissions - Determination of mass concentration of fluorinated compounds expressed as HF - Standard reference method

This European Standard specifies a manual method for the determination of the concentration of fluorinated compounds expressed in HF. Two cases are presented:
- first case: the measurand is the concentration of hydrofluoric acid and gaseous and bound to particulates fluorides,
- second case: the measurand is the concentration of hydrofluoric acid and gaseous fluorides.
Three analytical techniques are proposed: ionometry, spectrophotometry and ion-exchange chromatography.
This European Standard specifies the performance characteristics to be determined and the performance criteria to be fulfilled when it is used as the Standard Reference Method (SRM) for periodic monitoring and for calibration or control of Automated Measuring Systems (AMS) permanently installed on a stack, for regulatory or other purposes.
This document applies to more or less dust-laden flue gases whose HF concentration may vary between 0,1 mg/m3 and 10 mg/m3, at standard conditions of pressure and temperature. The quantification limit of the method is estimated at 0.1 mg/m3 for a sampled volume of 0.1 m3.

Emissionen aus stationären Quellen - Bestimmung der Massenkonzentration fluorierter Verbindungen, angegeben als HF - Standardreferenzverfahren

Dieses Dokument legt ein manuelles Verfahren zur Bestimmung der Konzentration fluorierter Verbindungen, angegeben als HF, fest. Zwei Fälle werden unterschieden:
- Erster Fall: Die Messgröße ist die Konzentration von gasförmigen und partikelgebundenen Fluoriden.
- Zweiter Fall: Die Messgröße ist die Konzentration von gasförmigen Fluoriden.
Drei Analyseverfahren werden vorgeschlagen: Ionometrie, Spektrophotometrie und Ionenaustauschchromatographie.
Dieses Dokument legt die zu bestimmenden Leistungskenngrößen und die zu erfüllenden Leistungskriterien fest, wenn das Verfahren als Standardreferenzverfahren (SRM) zur regelmäßigen Überwachung sowie Kalibrierung oder Kontrolle von dauerhaft im Abgaskanal installierten automatischen Messeinrichtungen (AMS) eingesetzt wird.
Dieses Dokument ist anwendbar für Fluoridkonzentrationen zwischen 0,1 mg HF/m3 und 10 mg HF/m3 bei Normbedingungen bezüglich Druck und Temperatur (siehe ANMERKUNG). Die Bestimmungsgrenze des Verfahrens wird für ein Probenvolumen von 0,1 m3 auf 0,1 mg/m3 geschätzt.
Bei einigen Matrizes können Störungen auftreten. Elemente, von denen bekannt ist, dass sie zu Störungen führen können, sind in Anhang C angegeben.
ANMERKUNG Die Emissionsgrenzwerte (ELV) für HF werden in mg/m3 für trockene Gase bei Normbedingungen (Tstd = 273 K und Pstd = 101,3 kPa) angegeben.

Émissions de sources fixes - Détermination de la concentration massique en composés fluorés, exprimée en HF - Méthode de référence normalisée

Le présent document spécifie une méthode manuelle permettant de déterminer la concentration en
composés fluorés, exprimée sous forme de concentration en HF. Deux cas sont présentés :
— premier cas : le mesurande est la concentration en fluorures gazeux et en fluorures liés aux
particules ;
— second cas : le mesurande est la concentration en fluorures gazeux.
Trois techniques d’analyse sont proposées : l’ionométrie, la spectrophotométrie et la chromatographie
ionique.
Le présent document spécifie les caractéristiques de performance à déterminer ainsi que les critères de
performance à satisfaire lorsqu’il est utilisé en tant que méthode de référence normalisée (SRM) pour la
surveillance périodique ainsi que pour l’étalonnage et le contrôle des systèmes de mesurage
automatisés (AMS) installés à demeure sur une cheminée, à des fins réglementaires ou autres.
Le présent document s’applique aux concentrations en fluorures qui peuvent varier entre 0,1 mg HF/m3
et 10 mg HF/m3, dans les conditions normales de température et de pression (voir NOTE). La limite de
quantification de la méthode est estimée à 0,1 mg/m3 pour un volume prélevé de 0,1 m3.
Des interférences peuvent exister pour certaines matrices. Les éléments connus pour être des sources
d’interférences potentielles sont mentionnés à l’Annexe C.
NOTE Les valeurs limites d’émission (VLE) pour le HF sont exprimées en mg/m3, sur gaz secs et dans les
conditions normales (Tstd = 273 K et Pstd = 101,3 kPa).

This Technical Specification (CEN/TS) was approved by CEN on 17 August 2020 for provisional application.

The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to
submit their comments, particularly on the question whether the CEN/TS can be converted into a European Standard.

CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS
available promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in
parallel to the CEN/TS) until the final decision about the possible conversion of the CEN/TS into an EN is reached.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,
Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and
United Kingdom.
