Ethanol as a blending component for petrol - Determination of sulfur content - Ultraviolet fluorescence method

Asnjë informacion i shtuar.

This document specifies an ultraviolet (UV) fluorescence test method for the determination of the sulfur content of ethanol from 5 mg/kg to 20 mg/kg. Other products may be analysed and higher sulfur contents may be determined according to this test method, however, no precision data for products other than ethanol and for results outside the specified range have been established for this document. Halogens interfere with this detection technique at concentrations above approximately 3 500 mg/kg. NOTE For the purposes of this document, the terms “% (m/m)” and “% (V/V)” are used to represent the mass fraction and the volume fraction of a material respectively.
