Stationary source emissions - Determination of the mass concentration of PCDDs/PCDFs and dioxin-like PCBs - Part 1: Sampling of PCDDs/PCDFs
This European Standard specifies the sampling of PCDDs/PCDFs. It is an integral part of the complete measurement procedure. The use of the other two parts prEN 1948-2:2005 and
prEN 1948-3:2005 describing extraction and clean-up and identification and quantification, respectively, is necessary for the determination of the PCDDs/PCDFs.
This European Standard has been developed 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 sampling.
The user has the possibility to choose between three different methods:
- "filter/condenser method"
- "dilution method"
- "cooled probe method"
Each sampling method is illustrated by some sampling systems described in detail in Annex B as examples of proven procedures.
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 which shall be met in order to measure the 17 congeners necessary to calculate the total I-TEQ (see Table A.1).
Besides the determination of PCDDs/PCDFs the described measurement methods are suitable for determination of other low-volatile substances, e.g. of dioxin-like PCBs (details for sampling and analyses see CEN/TS 1948-4), although no validated performance characteristics are avail
Emissionen aus stationären Quellen - Bestimmung der Massenkonzentration von PCDD/PCDF und dioxin-ähnlichen PCB - Teil 1: Probenahme von PCDD/PCDF
8
Diese Europäische Norm legt die Probenahme der PCDD/PCDF fest. Sie ist wesentlicher Bestandteil
des vollständigen Messverfahrens. Die Anwendung der anderen beiden Teile EN 1948-2:2006 und
EN 1948-3:2006, die die Extraktion und Reinigung bzw. die Identifizierung und Quantifizierung 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 Europäische Norm werden sowohl die Verfahrensvalidierung als auch ein Rahmen für die Qualitätskontrollanforderungen,
die bei jeder PCDD/PCDF-Probenahme erfüllt werden müssen, festgelegt.
Der Nutzer hat die Möglichkeit, zwischen drei unterschiedlichen Verfahren zu wählen:
⎯ Filter/Kühler-Methode;
⎯ Verdünnungsmethode;
⎯ Gekühltes-Absaugrohr-Methode.
Jedes Probenahmeverfahren wird durch einige Probenahmesysteme veranschaulicht, die ausführlich im Anhang
B als geprüfte Ausführungsbeispiele beschrieben 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/PCDF-Emissionsbereich von etwa
0,1 ng I-TEQ/m3 und einer Staubbeladung von 1 mg/m3 bis 15 mg/m3 durchgeführt. Obwohl diese Europäische
Norm hauptsächlich für Abgasemissionen aus Müllverbrennungsanlagen entwickelt und validiert wurde,
zeigen die praktischen Erfahrungen, dass sie auch für weite Konzentrationsbereiche und verschiedene Emissionsquellen
angewendet werden kann.
Das in den drei Teilen der EN 1948:2006 beschriebene Verfahren legt Anforderungen für die Bestimmung der
17 Kongenere fest, die zur Berechnung des Gesamt-I-TEQ benötigt werden (siehe Tabelle A.1).
Emissions de sources fixes - Détermination de la concentration massique en PCDD/PCDF et PCB de type dioxine - Partie 1: Prélèvement des PCDD/PCDF
La présente Norme européenne spécifie le prélèvement de PCDD/PCDF. Elle fait partie intégrante du mode opératoire complet de mesurage. L’utilisation des deux autres parties de la présente Norme (EN 1948 2 et EN 1948 3), décrivant d’une part l’extraction et la purification et d’autre part l’identification et la quantification, est nécessaire pour déterminer les PCDD et les PCDF.
Cette norme 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.
Cette norme spécifie à la fois les exigences de validation de la méthode et un ensemble d’exigences de contrôle qualité qui doivent être respectées pour tout prélèvement de PCDD/PCDF.
L’opérateur a la possibilité de choisir parmi trois méthodes différentes :
- « la méthode à filtre/condenseur » ;
- « la méthode à dilution » ;
- « la méthode à sonde refroidie ».
L’Annexe B illustre chaque méthode de prélèvement par quelques systèmes de prélèvement décrits en détail et donnés à titre d’exemple de modes opératoires éprouvés.
À la suite de mesurages comparatifs 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.
Le mode opératoire décrit dans les trois parties de la norme EN 1948 spécifie les exigences permettant de déterminer les 17 congénères nécessaires pour calculer l’I-TEQ total (voir le Tableau A.1).

Foreword
This European Standard (EN 1948-1:2006) 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 1948-1:1996.
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 E).
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
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.

1. Title: Broadening of the title with regard to the future EN 1948-4 for the determination of dioxin-like
PCBs
