This European Standard specifies a test method for the determination of the oxidation stability of fuels for diesel engines, by means of measuring the induction period of the fuel up to 48 h. The method is applicable to fatty acid methyl esters (FAME) intended for the use as pure biofuel or as a blending component for diesel fuels, and to blends of FAME with diesel fuel containing 2 % ( V\/V<\/i>) of FAME at minimum.<\/p>\n

\n
\n NOTE 1\n <\/div>\n

EN 14112<\/span> <\/span> [1]<\/span> describes a similar test method for oxidation stability determination of pure fatty acid methyl esters (see the Introduction to this European Standard).<\/p>\n<\/div>\n

\n
\n NOTE 2\n <\/div>\n

For induction periods higher than 48 h the precision is not covered by the precision statement of this method. The limit values of the relevant fuel standards are well within the scope of this test method.<\/p>\n<\/div>\n

\n
\n NOTE 3\n <\/div>\n

The presence of cetane improver can reduce the oxidation stability determined by this test method. Limited studies with EHN (2-ethyl hexyl nitrate) indicated, however, that the stability is reduced to an extent which is within the reproducibility of the test method.<\/p>\n<\/div>\n

\n
\n NOTE 4\n <\/div>\n

For the purposes of this European Standard, the term \u201c% ( V<\/i>\/ V<\/i>)\u201d is used to represent the volume fraction ( \u03c6<\/i>) of a material.<\/p>\n<\/div>\n
