This Standard specifies an ultraviolet fluorescence test method for the determination of the sulfur content of motor gasoline, kerosene and light oil having sulfur contents in the range of 0.0001 % TO 0.0500% mass fraction.<\/p>\n
\nThe method is applicable to motor gasolines, including those containing up to 3.7% mass fraction oxygen (e.g. those blended with ethanol up to about 10% volume fraction), and to light oils, including those containing up to 10% mass fraction fatty acid methyl ester (FAME).<\/p>\n
\nOther petroleum products and samples with the sulfur content exceeding 0.0500 % mass fraction and samples with the content of oxygen-containing compounds exceeding the specified range can be analysed according to this test method, however, no precision data for these analyses have been established for this Standard.<\/p>\n
\nNOTE 1 Halogens interfere with precise determination of sulfur content at concentrations above approximately 0.350 0 % mass fraction.<\/p>\n
\nNOTE 2 The sulfate species in ethanol have a conversion factor close to that of organic sulfur to sulfur dioxide.<\/p>\n
\nNOTE 3 For example, 2-ethyl hexyl nitrate (EHN) added as cetane improver to light oil shows an enhancing effect on sulfur content up to 0.000 17 % mass fraction, when 0.2000 % mass fraction EHN is added to light oil containing 0.001 0 % mass fraction sulfur.<\/p>\n
\nNOTE 4 The test methods specified in respective parts of JIS K 2541 series are shown in Annex JA.<\/p>\n
\nNOTE 5 The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.<\/p>\n
\nISO 20846: 2011 Petroleum products-Determination of sulfur content of automotive fuels-Ultraviolet fiuorescence method(MOD)<\/p>\n
\nIn addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard andJIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO\/IEC Guide 21-1.<\/p>\n
