scope:

Specifies the identification and quantification procedures of the samled PCDDs/PCDFs. It is an integral part of the completemeasurement procedure. The use of the other two Parts of this Standard, EN 1948-1:1996 and EN 1948-2:1996, describing sampling and extraction and cleanup, respectively, is necessary for the determination of the PCDDs/PCDFs. This standard has been designed to measure PCDD/PCDF concentrations at about 0,1 ng I-TEQ/m3 in stationary source emissions. Specifies both method validation and a framework of quality control requirements which have te be fulfilled by any PCDD/PCDF identification and quantification methods to be applied. During comparison measurements on a municipal waste incinerator at the level of about 0,1 ng I-TEQ/m3 these three 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.
