The present Part of the 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 1948-1:2003 and EN 1948-2:2003, describing sampling and extraction and clean-up, 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 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 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. These variabilities given an indication of the variabilities which have been observed when using this Standard and need to be taken into account when expressing results. The procedure described in the three parts of the EN 1948:2003 lays down 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 1948-1:2003).
