This document specifies a wavelength-dispersive X-ray
fluorescence (WDXRF) test method for the determination of the
sulfur content of liquid, homogeneous automotive fuels from
5Â mg/kg to 500Â mg/kg, which have a maximum oxygen content of
3,7Â %Â (m/m). This product range covers:
diesel fuels containing up to about 30Â %Â (
V/V) fatty acid methyl esters (FAME),
motor gasolines containing up to about 10Â %Â (
synthetic fuels such as hydrotreated vegetable oil (HVO) and
gas to liquid (GTL) having sulfur contents in the range of
5Â mg/kg to 45Â mg/kg.
Products with higher oxygen content show significant matrix
effects, e.g. pure FAME used as biodiesel, nevertheless, pure FAME
can be analysed when the corresponding procedures are followed (see
5.3 and 8.1).
Other products can be analysed with this test method, though
precision data for products other than those mentioned have not
been established for this document.
NOTEÂ 1 Sulfur contents higher than 500Â mg/kg can be determined
after sample dilution, however, the precision was not established
for diluted samples.
For the purposes of this document, â€œ%Â (
m/m)â€? and â€œ%Â (
V/V)â€? are used to represent the mass fraction,
w, and the volume fraction,
Ï†, of a material respectively.
