scope:
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 longterm 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 (see Annex C and Annex F).
With the methods described experiences were gained for a concentration range from typically 0,003 ng ITEQ/ m3 up to 4,0 ng I-TEQ/m3 and 0,003 ng WHO-TEQ/m3 up to 4,0 ng WHO-TEQ/m3 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 cleanup 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.
