Appearance – Clear and Bright – Visual Inspection
Property Units Max Test Method
Olefins % v/v 18.0 ASTM D 1319 (2)
Aromatics % v/v 35.0 ASTM D 1319 (2)
Total di-olefins %m/m 1.0 GCMS / HPLC
Notes:
1) GC/MS methods may also be applied to fully deconvolute the GC trace.
2) The above maximum values for olefins and aromatics are corrected for
fuel oxygenate content according to clause 13.2 of ASTM D 1319:1998.
b) The total od individual hydrocarbon components present at
concentrations of less than 5% m/m must constitute at least 30% m/m of
the fuel. The test method will be gas chromotography and/or GC/MS
c) The total concentration of napthenes, olefins and aromatics classified by
carbon number must not exceed the values given in the following table:
% C4 C5 C6 C7 C8 C9+
Napthenes 0 5 10 10 10 10
Olefins 5 20 20 15 10 10
Aromatics - - 1.2 35 35 30
The total concentration of bicyclic napthenes and bicyclic olefins may not be
higher than 1% (m/m). The test method used will be gas chromatography.
d) Only the following oxygenerates are permitted:
Methonol, ethenol, iso-propyl alcohol, iso-butyl alcohol, methyl tertiary butyl
ether, tertiary amyl methyl ether, di-isopropyl ether, n-propyl alcohol, tertiarybutyl
alcohol, n-butyl alcohol, secondary-butyl alcohol.
e) Manganese is not permitted in concentrations above 0.005 g/l. For the
present this is solely to cover possible minor contamination by other
fuels. The fuel will contain no substance that is capable of an exothermic
reaction in the absence of external oxygen.
Lead replacement petrols, although basically free of lead, are not an
alternative to the use of unleaded petrol. Such petrols may contain
unacceptable additives not consistant with FIM Regulations.
