This document specifies a test method for the determination of the content of mono-aromatic,
di-aromatic and tri+-aromatic hydrocarbons in diesel fuels, paraffinic diesel fuels and petroleum distillates.
This document defines two procedures, A and B.
Procedure A is applicable to diesel fuels that may contain fatty acid methyl esters (FAME) up to
30 % (
V/V) (as in [1], [2] or [3]) and petroleum distillates in the boiling range from 150 °C to 400 °C (as in [4].
Procedure B is applicable to paraffinic diesel fuels with up to 7 % (
V/V) FAME. This procedure does not
contain a dilution of the sample in order to determine the low levels of aromatic components in these fuels.
The polycyclic aromatic hydrocarbons content is calculated from the sum of di-aromatic and tri+-
aromatic hydrocarbons and the total content of aromatic compounds is calculated from the sum of the
individual aromatic hydrocarbon types.
Compounds containing sulfur, nitrogen and oxygen can interfere in the determination; mono-alkenes do
not interfere, but conjugated di-alkenes and poly-alkenes, if present, can do so.
NOTE 1 For the purpose of this European Standard, the terms "% (
m/m)" and "% (
V/V)" are used to represent the mass fraction, µ, and the volume fraction, φ, of a material respectively.
NOTE 2 By convention, the aromatic hydrocarbon types are defined on the basis of their elution characteristics from the specified liquid chromatography column relative to model aromatic compounds. Their quantification is performed using an external calibration with a single aromatic compound for each of them, which may or may not be representative of the aromatics present in the sample. Alternative techniques and test methods may classify and quantify individual aromatic hydrocarbon types differently.
NOTE 3 Backflush is part of laboratory-internal maintenance.
