This European Standard specifies a test method for
the determination of the content of mono-aromatic,
di-aromatic and tri+-aromatic hydrocarbons in diesel
fuels that may contain fatty acid methyl esters
(FAME) up to 5 % (V/V) and petroleum distillates in
the boiling range from 150 °C to 400 °C. 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
may interfere in the determination; mono-alkenes do
not interfere, but conjugated di-alkenes and
polyalkenes, if present, may do so.
The precision statement of the test method has
been established for diesel fuels with and without
FAME blending components, with a mono-aromatic
content in the range from 6 % (m/m) to 30 %
(m/m), a di-aromatic content from 1 % (m/m) to
10 % (m/m), a tri+-aromatic content from
0 % (m/m) to 2 % (m/m), a polycyclic aromatic
content from 1 % (m/m) to 12 % (m/m), and a total
aromatic content from 7 % (m/m) to 42 % (m/m).
