Scope

This European Standard specifies sampling from stationary sources, extraction, clean-up, identification and quantification procedures of the dioxin-like PCBs. The procedure described lays down requirements to measure the PCB congeners given in Annex A (see Table A.1). It is applicable to the 12 non- and mono-ortho PCB designated by the WHO. It is optimised to measure PCB concentrations of about 0,01 ng WHO-TEQPCB/m3.
In addition to the 12 non- and mono-ortho-PCB the present document is also applicable to measure further PCB-congeners like the "marker PCB" 28, 52, 101, 138, 153, 180 (see Annex F).
This document specifies a framework of quality control requirements which should be fulfilled by any PCB sampling, extraction, clean-up, identification and quantification methods to be applied.
As a result of their similar chemical behaviour PCBs, as shown in the validation campaign, can be sampled from stationary sources together with the PCDDs/PCDFs. Therefore, it is possible to measure PCBs together with PCDDs/PCDFs by applying EN 1948-1, -2, -3 and -4. The complete sampling procedure is described in EN 1948-1. Each of the three sampling methods of EN 1948-1 can be combined with the methods described in this document to complete the measurement procedure. EN 1948-1 is an integral part of the complete measurement procedure and is necessary for the determination of PCBs.
The analyses of the following PCB congeners is described in this European Standard and is validated in the validation campaign:
a) Non-ortho substituted PCBs
1) 3,3’,4,4’-TeCB(77)
2) 3,4,4’,5-TeCB (81)
3) 3,3’,4,4’,5-PeCB (126)
4) 3,3’,4,4’,5,5’-HxCB (169)
b) Mono-ortho substituted PCBs
1) 2,3,3’,4,4’-PeCB (105)
2) 2,3,4,4’,5-PeCB (114)
3) 2,3’,4,4’,5-PeCB (118)
4) 2’,3,4,4’,5-PeCB (123)
5) 2,3,3’,4,4’,5-HxCB (156)
6) 2,3,3’,4,4’,5’-HxCB (157)
7) 2,3’,4,4’,5,5’-HxCB (167)
8) 2,3,3’,4,4’,5,5’-HpCB (189)
c) Marker PCBs
1) 2,4,4'- TriCB (28)
2) 2,2',5,5'-TeCB (52)
3) 2,2',4,5,5'- PeCB
