Stationary source emissions - Determination of the mass concentration of PCDDs/PCDFs and dioxin-like PCBs - Part 5: Long-term sampling of PCDDs/PCDFs/PCBs

Publication date:   May 14, 2026

Scope

This document specifies the long-term sampling of PCDDs/PCDFs/PCBs. There are three different sampling methods, which are based on the three different principles described in 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 Annex D. 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 for any long-term sampling method.
With the methods described, experiences were gained for a concentration range up to 4,0 ng TEQ/m3 at various stationary sources (e.g. waste incinerators, sinter plants, cement kilns).
For complete implementation of the measurement method, the use of EN 1948 2 and EN 1948 3 describing extraction, clean-up, identification, and quantification, respectively, is necessary in order to determine PCDDs/PCDFs. Additionally, EN 1948 4 is necessary for PCBs.
