Petroleum products -- Determination of sulfur content of automotive fuels -- Wavelength-dispersive X-ray fluorescence spectrometry
Products with higher oxygen content show significant matrix effects, e.g. FAME used as biodiesel. Nevertheless, FAME may be analysed when the corresponding procedures are followed.
Other products may be analysed with this test method. However, precision data for products other than those mentioned have not been established for ISO 20884:2011.
