Petroleum products and used oils - Determination of PCBs and related products - Part 3: Determination and quantification of polychlorinated terphenyls (PCT) and polychlorinated benzyl toluenes (PCBT) content by gas chromatography (GC) using an electron capture detector (ECD)
This document specifies a method of test for the determination of polychlorinated terphenyls (PCT) and
polychlorinated benzyl toluenes (PCBT) in petroleum products and related materials by means of a specified
gas chromatographic separation procedure. Following the gas chromatographic separation, quantification
procedures are described for PCT Aroclor 5442, PCT Aroclor 5460 and PCBT (Ugilec 141).
This document is applicable to unused, used and treated (e.g. dechlorinated) petroleum products including
synthetic lubricating oils, to petroleum products and synthetic lubricating oils suitably recovered from other
materials (e.g. from waste materials) and to mixtures of vegetable oils.
NOTE 1 This document has been developed as an extension of EN 12766 Parts 1 and 2 to provide a method of
determining the total PCB content in accordance with Articles 2, 3 and 4 of EC Directive 96/59/EC [1]. The total PCB
content is calculated by summation of PCB content, determined according to EN 12766-2, and PCTs and PCBTs
according to this document.
The three classes of materials measured in this standard can be quantified if they occur at concentrations
greater than given in Table 1.
NOTE 2 In order to simplify and rationalize the analytical operations required for an effective, fast and economic
inventory of equipment containing liquids classified as PCBs (as defined by Directive 96/59/EC [1]), it is recommended
firstly to determine, using an appropriate screening method, the total chlorine content (in mg/kg). Examples for analytical
procedures to determine total chlorine content in fresh, used, or treated insulating oils are:
i) pre-dosed colorometric kits to measure 25 mg/kg or 50 mg/kg total chlorine (ref: US EPA SW-846
Method 9079);
ii) electrochemical methods in the range 2 mg/kg to 2 000 mg/kg of total chlorine
(ref: DEXSIL® L-2000 DXC - US EPA SW-846 Method 9079 and US EPA SW-846 Method 9078);
iii) waveleng (...abbreviated)
Diese Norm legt ein Verfahren zur Bestimmung von polychlorierten Terphenylen (PCT) und polychlorierten Benzyltoluolen (PCBT) in Mineralölprodukten und verwandten Stoffgemischen durch ein standardisiertes gaschromatographisches Trennverfahren fest. Unter Einhaltung der vorgeschriebenen gaschromatographischen Trennung werden die unterschiedlichen Quantifizierungsmethoden auf der Basis von PCT Aroclor 5442 und PCT Aroclor 5460 sowie für PCBT auf der Basis von Ugilec 141 beschrieben. Diese Norm ist anwendbar auf frische, gebrauchte und behandelte (z.B. dechlorierte) Mineralölerzeugnisse einschließlich synthetischer Schmieröle und auf Mineralölerzeugnisse und synthetische Schmieröle, die mit geeigneten Verfahren aus anderen Materialien, wie z.B. aus Abfallprodukten zurückgewonnen wurden, sowie auf Gemische aus Pflanzenölen.
