This part of the Standard specifies the sampling of PCDDs/PCDFs. It is an integral part of the complete measurement procedure. The use of the other two parts EN 1948-2:2003 and EN 1948-3:2003 describing extraction and clean-up and identification and quantification, respectively, is necessary for the determination of the PCDDs/PCDFs. This Standard has been developed to measure 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 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 on municipal waste incinerators at the level of about 0,1 ng I-TEQ/m 3 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/ m 3 and a dust loading of from 1 mg/m 3 to 15 mg/m 3 . 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 give 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 EN 1948:2003 specifies requirements which shall be met in order to measure the 17 congeners necessary to calculate the total I-TEQ (see Table A.1).
