Stationary source emissions - Determination of the mass concentration of PCDDs/PCDFs and dioxin-like PCBs - Part 4: Sampling and analysis of dioxin-like PCBs

1) EN 1948-4 was elaborated with special carefulness and was validated by extensive validation measurements covering a wide concentration range. Nevertheless the described selection of the sampling standards (see EN 1948-4, Table 1) causes co-elution problems of PCB 127 and PCB 105 on the most common columns. The use of the columns HT-8 or Agilent XLB can avoid these co-elution problems, but they are not so common for routine analyses. The sampling standard PCB 127 was chosen in order to monitor the similar and most toxic congener PCB 126 and is of special importance for plants which mainly emit PCBs. In order to avoid the co-elution problems during routine analyses a more flexible specification is given and the following footnote to EN 1948-4, Table 1, is added:  Footnote b) Sampling standards: Attention should be paid to possible co-elution problems of PCB 127 and PCB 105 on certain commercially available columns. If the co-elution problems cannot be avoided, it is allowed to omit the sampling standard PCB 127.  2) In order to avoid any misunderstanding with regard to the sampling compartments to be spiked with labelled standards a reference to EN 1948-1 should be added to the first sentence of EN 1948-4, Clause 6.2:  "The sampling standards (see Table 1) shall be added to the different sampling media before sampling and the extraction standards shall be added to the samples before extraction according to EN 1948 Part 1."

This draft amendment is submitted to CEN members for unique acceptance procedure. It has been drawn up by the Technical Committee
CEN/TC 264.

This draft amendment A1, if approved, will modify the European Standard EN 1948-4:2010. If this draft becomes an amendment, CEN
members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for inclusion of this amendment
into the relevant national standard without any alteration.

This draft amendment was established by CEN in three official versions (English, French, German). A version in any other language made
by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management Centre has
the same status as the official versions.
