scope:

This International Standard specifies an ultraviolet (UV) fluorescence test method for the determination of the sulfur content of motor gasolines, including those containing up to 2,7% (m/m) oxygen, and of diesel fuels, including those containing up to 5% (v/v) fatty acid methyl ester (FAME), having sulfur contents in the range 3mg/kg to 500 mg/kg. Other products may be analysed and other sulfur contents may be determined according to this test method; however, no precision data for products other than automotive fuels and for results outside the specified range have been established for this International Standard. Halogens interfere with this detection technique at concentrations above approximately 3500 mg/kg.
