DIN Standards Committee Materials Testing

Overview

This document contains the German translation of the international document ISO 20884:2011 which has been prepared by Technical Committee ISO/TC 28 "Petroleum products and lubricants", the secretariat of which is held by ASTM (USA), in collaboration with Technical Committee CEN/TC 19 "Gaseous and liquid fuels, lubricants and related products of petroleum, synthetic and biological origin". The responsible national committee is NA 062-06-81 AA, Mirror Committee of CEN/TC 19 "Gaseous and liquid fuels, lubricants and related products of petroleum, synthetic and biological origin" at the Petroleum, Fuels, Lubricants and Related Products Standardization Committee (FAM) of the Materials Testing Standards Committee (NMP). This International Standard specifies a wavelength-dispersive X-ray fluorescence (WDXRF) test method for the determination of the sulfur content of liquid, homogeneous automotive fuels from 5 mg/kg to 500 mg/kg, which have a maximum oxygen content of 3,7 % (m/m). The scope covers diesel fuels containing up to about 10 % (V/V) fatty acid methyl esters (FAME) and motor gasolines containing up to about 10 % (V/V) ethanol. Sulfur contents higher than 500 mg/kg can be determined after sample dilution. However, the precision was not established for diluted samples. Products with higher oxygen content show significant matrix effects, for example, biodiesel [fatty acid methyl ester (FAME)]. Nevertheless, biodiesel may be analysed when the corresponding procedures are. Other products may be analysed with this test method; however, precision data for products other than those mentioned have not been established.
