適用范圍：This European Standard specifies the extraction and clean-up procedures of the sampled PCDDs/PCDFs. It isan integral part of the complete measurement procedure. The use of the other two parts EN 1948-1:2006 andEN 1948-3:2006 describing sampling or identification and quantification, respectively, is necessary for thedetermination of the PCDDs/PCDFs.This European Standard has been designed to measure PCDD/PCDF concentrations at about0,1 ng I-TEQ/m3 in stationary source emissions.This European Standard specifies both method validation and a framework of quality control requirementswhich shall be fulfilled by any PCDD/PCDF extraction and clean-up methods to be applied. Some methodsare 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) andthe identification and quantification (Part 3) to complete the measurement procedure.During comparison measurements of the three sampling methods on municipal waste incinerators at the levelof about 0,1 ng I-TEQ/m3 these methods have been deemed comparable within the expected range ofuncertainty. Validation trials were performed on the flue gas of municipal waste incinerators at the level ofabout 0,1 ng I-TEQ/m3 and a dust loading of from 1 mg/m3 to 15 mg/m3. Although this European Standard isprimarily developed and validated for gaseous streams emitted by waste incinerators, the practical experienceshows 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 which shall be met inorder to measure the 17 congeners necessary to calculate the total I-TEQ (see Table A.1 ofEN 1948-1:2006).Besides the determination of PCDDs/PCDFs the described measurement methods are suitable fordetermination of other low-volatile substances, e.g. of dioxin-like PCBs (details for sampling and analyses seeCEN/TS 1948-4), although no validated performance characteristics are available yet.
