ISO 20847:2004

Petroleum products - Determination of sulfur content of automotive fuels - Energy-dispersive X-ray fluorescence spectrometry

PUBLISH DATE 2004
ISO 20847:2004

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:

  • Leaded motor gasolines,
  • Lead-replacement gasolines containing 8 mg/kg potassium to 20 mg/kg potassium,
  • Products and feedstocks containing lead, silicon, phosphorus, calcium, potassium or halides at concentrations greater than one-tenth of the concentration of sulfur measured.
