Petroleum products - Determination of low concentration of sulfur in automotive fuels - Energy-dispersive X-ray fluorescence spectrometric method (ISO 13032:2012)

Asnjë informacion i shtuar.

This European Standard specifies an energy dispersive X-ray fluorescence (EDXRF) test method for the determination of the sulfur content of automotive gasolines, including those containing up to 5 % (m/m) oxygen, and of automotive diesel fuels, including those containing up to 10 % (V/V) fatty acid methylester (FAME), having sulfur contents in the range 2 mg/kg to 50 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 standard. For reasons of spectral overlap, this standard is not applicable to leaded automotive gasolines, lead replacement gasolines containing greater than 8 mg/kg lead, or to products and feedstocks containing lead, silicon, phosphorus, calcium, potassium or halides at concentrations greater than one tenth of the concentration of sulfur measured or more than 10 mg/kg, whichever is the greater.
