The present Part of this Standard specifies the extraction and clean-up procedures of the sampled PCDDs/PCDFs. It is integral part of the complete measurement procedure. The use of the other two parts EN 1948-1:2003 and EN 1948-3:2003 describing sampling or identification and quantification, respectively, is necessary for the determination of the PCDDs/PCDFs. This Standard has been designed to measure PCDD/PCDF concentrations at about 0,1 ng I-TEQ/m 3 in stationary source emissions. This Standard specifies both method validation and a framework of quality control requirements which have to be fulfilled by any PCDD/PCDF extraction and clean-up 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 on a municipal waste incinerator at the level of about 0,1 ng I-TEQ/m³ these three 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. In principle it is not possible to evaluate the accuracy (trueness and precision) of emission measurements. Following the validation trials the internal and external variabilities were calculated for the process considered and are given in clause 14 of EN 1948-3:2003. These variabilities given an indication of the variabilities which have been observed when using this standard and should be taken into account when expressing results. The procedure described in the three Parts of Standard EN 1948:2003 lays down requirements in order to measure the 17 congeners required to calculate the total I-TEQ (see Table A.1 of EN 1948-1:2003).
