ÖNORM EN 12766-1

This European Standard specifies a method to determine the concentration of up to 12 individual or defined unresolved small groups of polychlorinated biphenyl (PCB) congeners in petroleum products and related materials by means of a specified gaschromatographic separation procedure. The gas chromatographic separation is valid for the different quantification procedures described in Part 2 of this European Standard. This European Standard is applicable to unused, used and treated (e.g. dechlorinated) petroleum products including synthetic lubricating oils, and to petroleum products and synthetic lubricating oils suitably recovered from other materials, e.g. from waste materials. NOTE 1 The nominal application range does depend on precision, the lower limit per single congener is about 0,2 mg/kg. NOTE 2 For the purposes of this European Standard, the terms % (V/V) and % (m/m) are used to represent respectively the mass fraction and the volume fraction. This European Standard does not apply to insulating liquids, for which a different method (EN 61619) is available. Depending on current legislation, it may be necessary to measure either total or individual PCB congeners. EN 61619 may be followed as an alternative method for the determination of total PCBs, using the clean-up stage described in clause 8 of this standard. WARNING : The use of this standard can involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
