Scope

This Standard specifies the test method that uses combustion-ion
chromatography to determine fluorine, chlorine and sulfur content in petroleum
products, interference, instruments and equipment, reagents and materials,
sampling, preparation, calibration, test procedures, calculation of results,
expression of results, as well as precision and deviation.
This Standard is applicable to the determination of fluorine, chlorine and sulfur
content in petroleum products of which the boiling point range is 30°C~380°C
and the determination range is 0.30mg/kg~15.00mg/kg, including gasoline,
ethanol gasoline, naphtha, distillate, jet fuel, diesel, biodiesel blended fuel. This
method can be also used for the samples outside this range, but the precision
has not been determined.
