标准简介：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, EN 1948-1:2006 and EN 1948-2:2006, 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 ITEQ/
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 EN 1948:2006 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 EN
1948-1:2006).
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 available yet.
