17、cal Committee CEN/TC 264 “Air quality”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2006, and conflicting national standards shall be withdra
18、wn at the latest by September 2006. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This European Standard supersedes EN 1948-1:1996.
19、This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association to support Essential Requirements of EU Directive 94/67/EC of 16 December 1994 i on the incineration of hazardous waste. This directive is now replaced by EU Direc
20、tive 2000/76/EC of 4 December 2000 on the incineration of waste ii and this European Standard also supports the Essential Requirements of the new EU Directive 2000/76/EC (see also Annex E). The precision and the performance characteristics were determined between 1992 and 1995 in four comparative an
21、d validation trials at waste incinerators sponsored by the European Commission, the European Free Trade Association and the German Federal Environment Agency. The revision of this EN between 2001 and 2004 only refers to the normative part. The information given in the informative annexes as examples
22、 of operation are kept unchanged, as they represent the state of the art at time of the validation measurements of EN 1948:1996 between 1992 and 1995. This European Standard EN 1948:2006 consists of three parts dealing with the determination of the mass concentration of PCDDs and PCDFs in stationary
23、 source emissions: Part 1: Sampling of PCDDs/PCDFs; Part 2: Extraction and clean-up of PCDDs/PCDFs; Part 3: Identification and quantification of PCDDs/PCDFs. All three parts are necessary for the performance of the dioxin measurements. In addition for the sampling, extraction and analyses of dioxin-
24、like PCBs the Technical Specification CEN/TS 1948-41is developed and will be transferred to a European Standard after corresponding validation measurements or after an approval time of three years respectively. Important changes made in the revision of EN 1948-1: 1. Title: Broadening of the title wi

EN 1948-1:2006 (E) 7 Introduction Two groups of related chlorinated aromatic ethers are known as polychlorinated dibenzodioxins (PCDDs) and polychlorinated dibenzof
48、urans (PCDFs); they consist of a total of 210 individual substances (congeners): 75 PCDDs and 135 PCDFs. PCDDs and PCDFs can form in the combustion of organic materials; they also occur as undesirable by-products in the manufacture or further processing of chlorinated organic chemicals. PCDDs/PCDFs
49、enter the environment via these emission paths and through the use of contaminated materials. In fact, they are universally present in very small concentrations. The 2,3,7,8-chlorine substituted congeners are toxicologically significant. Toxicologically much less significant than tetrachlorinated to octachlorinated dibenzodioxins/-dibenzofurans are the 74 monochlorinated to trichlorinated dibenzodioxins/dibenzofurans (for toxicity equivalent factors, see Annex A).
