Short description
This European Standard specifies the long-term sampling of PCDDs/PCDFs/PCBs. There are three different sampling methods, which are based on the three different principles described of EN 1948-1, but partially modified for long-term sampling requirements: - filter/condenser method; - dilution method; - cooled probe method. Each sampling method is illustrated in detail in an Annex. The sampling methods described in this document are designed for a sampling duration of typically up to four weeks. Additionally, this document specifies a framework of quality control requirements to be applied respectively recommended for any long-term sampling method. With the methods described, experiences were gained for a concentration range up to 4,0 ng TEQ/m³, respectively at various stationary sources (e. g., waste incinerators, sinter plants, cement kilns).
