EN ISO 20846 Petroleum Products, Determination of Sulfur Content of Automotive Fuels, Ultraviolet Fluorescence Method

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN ISO 20846 testing. This standard specifies an ultraviolet (UV) fluorescence test method for determining the sulfur content of the following products:

EN ISO 20846 Petroleum Products, Determination of Sulfur Content of Automotive Fuels, Ultraviolet Fluorescence Method

  • With sulfur content in the range of 3 mg/kg to 500 mg/kg,
  • Motor gasoline containing up to 3,7% (m/m) oxygen [including those blended with up to about 10% (V/V) ethanol],
  • Diesel fuels, including those containing up to 30% (V/V) fatty acid methyl ester (FAME)
  • With sulfur content in the range of 3 mg/kg to 45 mg/kg,
  • Synthetic fuels such as hydrotreated vegetable oil (HVO) and gas-to-liquid (GTL).

Other products can be analyzed and other sulfur contents determined according to this test method, but precision data for products other than automotive fuels and results outside the specified range have not been established for this document. Halogens interfere with this detection technique at concentrations above about 3 500 mg/kg.

Some process catalysts used in petroleum and chemical refining can be poisoned when traces of sulfur-containing materials are present in the raw materials.

This test method can be used to determine sulfur in process feeds and can also be used to control sulfur in wastewater.

The sulfate species in ethanol do not have the same conversion factor as organic sulfur in ethanol. However, sulfates have a conversion factor close to that of organic sulfur.
