適用范圍：This European Standard specifies the identification and quantification procedures of the sampledPCDDs/PCDFs. It is an integral part of the complete measurement procedure. The use of the other two partsof 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 requirementswhich shall be fulfilled by any PCDD/PCDF identification and quantification methods to be applied. Somemethods 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) 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 in order to measure every2,3,7,8-chlorine substituted PCDD/PCDF congener required to calculate the total I-TEQ (see Table A.1 of EN1948-1:2006).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.
