Stationary source emissions - Determination of the mass concentration of PCDDs/PCDFs and dioxin-like PCBs - Part 3: Identification and quantification of PCDDs/PCDFs
This European Standard specifies the identification and quantification procedures of the sampled PCDDs/PCDFs. It is an integral part of the complete measurement procedure. The use of the other two parts of this standard, prEN 1948-1:2005 and prEN 1948-2:2005, describing sampling and extraction and clean-up, respectively, is necessary for the determination of the PCDDs/PCDFs.
This European Standard has been designed to measure PCDD/PCDF concentrations at about 0,1 ng I-TEQ/m3 in stationary source emissions.
This European Standard specifies both method validation and a framework of quality control requirements which shall be fulfilled by any PCDD/PCDF identification and quantification methods to be applied. Some methods are described in detail in Annex A as examples of proven procedures.
Each of the three sampling methods (Part 1) can be combined with the extraction and clean-up (Part 2) and the identification and quantification (Part 3) to complete the measurement procedure.
During comparison measurements of the three sampling methods on municipal waste incinerators at the level of about 0,1 ng I-TEQ/m3 these methods have been deemed comparable within the expected range of uncertainty. Validation trials were performed on the flue gas of municipal waste incinerators at the level of about 0,1 ng I-TEQ/m3 and a dust loading of from 1 mg/m3 to 15 mg/m3. Although this European Standard is primarily developed and validated for gaseous streams emitted by waste incinerators, the practical experience shows that it can be applied for wide concentration ranges and various emission sources.
The procedure described in the three parts of prEN 1948:2005 specifies requirements in order to measure every 2,3,7,8-chlorine substituted PCDD/PCDF congener required to calculate the total I-TEQ (see Table A.1 of prEN 1948-1:2005).
Besides the determination of PCDDs/PCDFs the described measurement methods are suitable for determination of other low-volatile substances, e.g. of dioxin-
Emissionen aus stationären Quellen - Bestimmung der Massenkonzentration von PCDD/PCDF und dioxin-ähnlichen PCB - Teil 3: Identifizierung und Quantifizierung von PCDD/PCDF
Diese Europäische Norm legt das Identifizierungs- und Quantifizierungsverfahren für die gesammelten
PCDD/PCDF fest. Sie ist integraler Bestandteil des vollständigen Messverfahrens. Die Anwendung der
anderen beiden Teile dieser Norm EN 1948-1:2006 und EN 1948-2:2006, die die Probenahme bzw. die
Extraktion und Reinigung beschreiben, ist notwendig für die Bestimmung der PCDD und PCDF.
Diese Europäische Norm ist für die Messung von PCDD/PCDF-Emissionskonzentrationen von stationären
Quellen im Bereich von 0,1 ng I-TEQ/m3 konzipiert.
In dieser Europäischen Norm werden sowohl die Verfahrensvalidierung als auch ein Rahmen für die
Qualitätskontrollanforderungen, die von allen anzuwendenden Verfahren zur Identifizierung und
Quantifizierung der PCDD/PCDF erfüllt werden müssen, festgelegt. Im Anhang A werden einige Verfahren als
erprobte Ausführungsbeispiele ausführlich beschrieben.
Jedes der drei Probenahmeverfahren (Teil 1) kann mit der Extraktion und Reinigung (Teil 2) und der
Identifizierung und Quantifizierung (Teil 3) zur Vervollständigung des Messverfahrens kombiniert werden.
Anhand von Vergleichsmessungen, die mit den drei Probenahmeverfahren an städtischen
Müllverbrennungsanlagen bei einer PCDD/PCDF-Emission von 0,1 ng I-TEQ/m3 durchgeführt wurden,
wurden diese drei Verfahren innerhalb des erwarteten Unsicherheitsbereiches für gleichwertig erachtet. Die
Validierungsmessungen wurden im Abgas von städtischen Müllverbrennungsanlagen im PCDD/PCDFEmissionsbereich
von etwa 0,1 ng I-TEQ/m3 und einer Staubbeladung von 1 mg/m3 bis 15 mg/m3
durchgeführt.
Emissions de sources fixes - Détermination de la concentration massique en PCDD/PCDF et PCB de type dioxine - Partie 3: Identification et quantification de PCDD/PCDF
La présente Norme européenne spécifie les modes opératoires d’identification et de quantification des PCDD/PCDF prélevés. Elle fait partie intégrante du mode opératoire complet de mesurage. L’utilisation des deux autres parties de la présente Norme (EN 1948 1:2006 et EN 1948 2:2006), décrivant d’une part le prélèvement et d’autre part l’extraction et la purification, est nécessaire pour déterminer les PCDD et les PCDF.
La présente Norme européenne a été élaborée pour mesurer des concentrations en PCDD/PCDF de l’ordre de 0,1 ng I-TEQ/m3 dans les émissions de sources fixes.
Elle spécifie à la fois les exigences de validation de la méthode et un ensemble d’exigences de contrôle qualité qui doivent être respectées dans toute méthode d’identification et de quantification des PCDD/PCDF utilisée. L’Annexe A présente quelques méthodes détaillées à titre d’exemples de modes opératoires éprouvés.
Chacune des trois méthodes de prélèvement (Partie 1) peut être combinée avec les méthodes d’extraction et de purification (Partie 2) et d’identification et de quantification (Partie 3) afin de compléter le mode opératoire de mesurage.
À la suite de mesurages comparatifs des trois méthodes de prélèvement effectués sur les fumées d’un incinérateur d’ordures ménagères à un niveau d’émission d’environ 0,1 ng l-TEQ/m3, ces trois méthodes ont été jugées comparables dans la plage d’incertitude attendue. Des essais de validation ont été effectués sur les fumées d’incinérateurs d’ordures ménagères à un niveau d’émission d’environ 0,1 ng I-TEQ/m3 et à une concentration en poussières allant de 1 mg/m3 à 15 mg/m3. Bien que la présente Norme européenne ait été élaborée et validée à l’origine pour des effluents gazeux émis par des incinérateurs, la pratique montre qu’elle peut s’appliquer à des plages de concentrations larges et à diverses sources d’émission.

Foreword
This European Standard (EN 1948-3:2006) has been prepared by Technical Committee CEN/TC 264 “Air
quality”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by September 2006, and conflicting national standards shall be
withdrawn at the latest by September 2006.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
This European Standard supersedes EN 1948-3:1996.
This European Standard has been prepared under a mandate given to CEN by the European Commission
and the European Free Trade Association to support Essential Requirements of EU Directive 94/67/EC of
16 December 1994 [i] on the incineration of hazardous waste. This directive is now replaced by EU Directive
2000/76/EC of 4 December 2000 on the incineration of waste [ii] and this European Standard also supports
the Essential Requirements of the new EU Directive 2000/76/EC (see also Annex G).
The precision and the performance characteristics were determined between 1992 and 1995 in four
comparative and validation trials at waste incinerators sponsored by the European Commission, the European
Free Trade Association and the German Federal Environment Agency.
The revision of this EN between 2001 and 2004 only refers to the normative part. The information given in the
informative annexes as examples of operation are kept unchanged, as they represent the state of the art at
the time of the validation measurements of EN 1948:1996 between 1992 and 1995.
This European Standard EN 1948:2006 consists of three parts dealing with the determination of the mass
concentration of PCDDs and PCDFs in stationary source emissions:
Part 1: Sampling of PCDDs/PCDFs;
Part 2: Extraction and clean-up of PCDDs/PCDFs;
Part 3: Identification and quantification of PCDDs/PCDFs.
All three parts are necessary for the performance of the dioxin measurements.
In addition for the sampling, extraction and analyses of dioxin-like PCBs the Technical Specification
CEN/TS 1948-4 is developed and will be transferred to a European Standard after corresponding validation
measurements or after an approval time of three years respectively.
Important changes made in the revision of EN 1948-3:
1. Title: Broadening of the title with regard to the future EN 1948-4 for the determination of dioxin-like
PCBs

Introduction
Two groups of related chlorinated aromatic ethers are known as polychlorinated dibenzodioxins (PCDDs) and
polychlorinated dibenzofurans (PCDFs); they consist of a total of 210 individual substances (congeners):
75 PCDDs and 135 PCDFs.
PCDDs and PCDFs can form in the combustion of organic materials; they also occur as undesirable by-
products in the manufacture or further processing of chlorinated organic chemicals. PCDDs/PCDFs enter the
environment via these emission paths and through the use of contamina
