This Technical Specification specifies the long-term sampling of PCDDs, PCDFs and PCBs. There are three different sampling methods, which use the three different principles described in EN 1948-1 modified for long-term sampling requirements: - filter/condenser method; - dilution method; - cooled probe method. Each sampling method is illustrated in detail in Annex D. The sampling methods described in this document are designed for a sampling duration of typically four weeks. Additionally this document specifies a framework of quality control requirements for any long-term sampling method to be applied. With the methods described experiences were gained for a concentration range from typically 0,003 ng I-TEQ/m 3 up to 4,0 ng I-TEQ/m 3 and 0,003 ng WHO-TEQ/m 3 up to 4,0 ng WHO-TEQ/m 3 respectively at different stationary sources (e. g. waste incinerators, sinter plants, cement kilns). For the complete measurement method the use of EN 1948-2 and EN 1948-3 describing extraction and clean-up and identification and quantification, respectively, is necessary in order to determine PCDDs/PCDFs. Also EN 1948-4 is necessary for the analyses of dioxin-like PCBs.
