Petroleum products - Determination of boiling range distribution by gas chromatography method - Part 1: Middle distillates and lubricating base oils
EN 15199-1:2020

This European Standard specifies a method for the determination of the boiling range distribution of petroleum products by capillary gas chromatography using flame ionisation detection. The standard is applicable to materials having a vapour pressure low enough to permit sampling at ambient temperature and a boiling range of at least 100 °C. The standard is applicable to distillates with initial boiling points (IBP) above 100 °C and final boiling points (FBP) below 750 °C, for example, middle distillates and lubricating base stocks.
The test method is not applicable for the analysis of petroleum or petroleum products containing low molecular weight components (for example naphthas, reformates, gasolines, diesel). Components containing hetero atoms (for example alcohols, ethers, acids, or esters) or residue are not to be analyzed by this test method.
NOTE   For the purposes of this European Standard, the terms “% (m/m)” and “% (V/V)” are used to represent respectively the mass fraction and the volume fraction.
WARNING — The use of this European Standard may involve hazardous materials, operations and equipment. This European 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 to determine the applicability of regulatory limitations prior to use.

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)
EN 12766-3:2004

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.
Table 1 - Concentrations for quantification
Class of material   Minimumconcentration   Method applied
PCB, polychlorinated biphenyls   8 mg / kg   (EN 12766-2 - Method A)
   4 mg / kg   (EN 12766-2 - Method B)
PCT   10 mg / kg   (EN 12766-3)
PCBT   5 mg / kg   (EN 12766-3)
Total PCB and related products a   25 mg / kg   (EN 12766-2 and EN 12766-3)
a This value is only a best estimate. Real field conditions may, depending on the concentrations in the three different classes, result in other, more limited or more improved application ranges. It is the user's responsibility to demonstrate that the analysis has been performed in a valid calibrated concentration range.

Petroleum products and used oils - Determination of PCBs and related products - Part 2: Calculation of polychlorinated biphenyl (PCB) content
EN 12766-2:2001

This standard specifies two calculation procedures ("method A" and "method B") for PCB content. The basis for this quantification is taken from the chromatographic results of EN 12766-1:2000 in which all necessary experimental procedures are described for the specific analysis of unused, used and treated (e.g. dechlorinated) petroleum products including synthetic lubricating oils and mixtures of vegetable oils. The method is also applicable to petroleum products and synthetic lubricating oils suitably recovered from other materials, e.g. from waste materials. Both methods have different strengths and weaknesses which are described in the next paragraphs and which must be considered before use in a specific application. Proper application of either method A or method B needs to be carefully considered before use in a specific application.
Using method A, special care needs to be exercised to avoid interferences from non PCB substances which may occur in the chromatogram. Therefore, method A can be used predominantly for the analysis of used and unused insulating oils. It is recommended not to use calculation method A without special precautions for other than above-mentioned products. Calculation method A can produce two alternative sets of results, ("All Probables" and "All Possibles"). Therefore, care needs to  be taken in order to interpret these results in the correct manner.
Method B uses as intermediate result the sum of six congeners, which belong to the most abundant in almost all technical PCB materials, thereby minimizing potential interferences from other (coeluting) non PCB substances. To obtain the PCB content, the intermediate sum from six congeners needs to be multiplied by a multiplication factor. Calculation Method B can be used predominantly for the analysis of liquids from used and waste materials of unknown origin and for samples with low PCB contents.

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.

Petroleum products and lubricants - Triaryl phosphate ester turbine control fluids (category ISO-L-TCD) - Specifications
EN 61221:2004

Specifies the characteristics of unused triaryl phosphate ester fluids for turbine governor controls and other hydraulic systems in electrical power stations. Fluids used in this application are classified under category TCD of ISO 6743-5. The major changes with regard to the first edition concern the need to upgrade the report to an International Standard, taking account of changes to the specification. The changes made include: a) introduction of new tests to define fire resistance, namely the Manifold Ignition and Wick flame persistence tests; b) flame persistence tests; c) introduction of a pour point requirement; d) a change to the Sequence II foaming requirement; e) introduction of a cleanliness requirement; f) introduction of an elastomer compatibility requirement; g) use of ISO test methods equivalent ot the original DIN tests.
