标准简介：This European Standard has been developed to measure PCDD/PCDF concentrations at about
0,1 ng I-TEQ/m3 in stationary source emissions.
This European Standard specifies both method validation and a framework of quality control requirements
which shall be fulfilled by any PCDD/PCDF sampling.
The user has the possibility to choose between three different methods:
⎯ "filter/condenser method"
⎯ "dilution method"
⎯ "cooled probe method"
Each sampling method is illustrated by some sampling systems described in detail in Annex B as examples of
proven procedures.
During comparison measurements of the three sampling methods on municipal waste incinerators at the level
of about 0,1 ng I-TEQ/m3 these methods have been deemed comparable within the expected range of
uncertainty. Validation trials were performed on the flue gas of municipal waste incinerators at the level of
about 0,1 ng I-TEQ/m3 and a dust loading of from 1 mg/m3 to 15 mg/m3. Although this European Standard is
primarily developed and validated for gaseous streams emitted by waste incinerators, the practical experience
shows that it can be applied for wide concentration ranges and various emission sources.
The procedure described in the three parts of EN 1948 specifies requirements which shall be met in order to
measure the 17 congeners necessary to calculate the total I-TEQ (see Table A.1).
Besides the determination of PCDDs/PCDFs the described measurement methods are suitable for
determination of other low-volatile substances, e.g. of dioxin-like PCBs (details for sampling and analyses see
CEN/TS 1948-4), although no validated performance characteristics are available yet.
