Petroleum products - Determination of sulfur content of automotive fuels - Energy-dispersive X-ray fluorescence spectrometry
ISO 20847:2004 specifies an energy dispersive X-ray fluorescence (EDXRF) 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 methylester (FAME), having sulfur contents in the range 30 mg/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 ISO 20847:2004.
For reasons of spectral overlap, ISO 20847:2004 is not applicable to:
