Scope

This standard section describes the extraction and processing of PCDD/PCDF, which is an integrated part of the complete measurement process. The use of the other two parts, SS-EN 1948-1:2006 and SS-EN 1948-3:2006, which cover sampling, identification, and quantification respectively, is necessary for determining PCDD/PCDF levels. This standard was developed to measure PCDD/PCDF concentrations around 0.1 ng I-TEQ/m³ in emissions from stationary sources. It describes both the validation of methods and a quality control framework that must be met by every method used for extracting and processing PCDD/PCDFs that will be applied. Some methods are detailed in Annex A as examples of tested procedures. Any one of the three sampling procedures (Part 1) can be combined with extraction and processing (Part 2) and identification and quantification (Part 3) to form a complete measurement procedure. Validation tests have been conducted on emissions from household waste incineration plants at levels around 0.1 ng I-TEQ/m³, finding these methods to be equivalent within the expected uncertainty range. Validation trials were carried out on gases from household waste incineration plant emissions at concentrations ranging from 1 mg/m³ to 15 mg/m³ and dust loadings. Although this European Standard was primarily developed and validated for gas streams emitted from waste incineration plants, practical experience shows that it can be applied over a wide concentration range and various emission sources. The procedure described in the three parts of SS-EN 1948:2006 defines requirements to be met for measuring the 17 congeners necessary to calculate total I-TEQ (see Table A.1 in SS-EN 1948-1:2006).
