This European Standard specifies a method for the determination of the oxidation stability of fatty acid methyl esters (FAME) at 110°C, by means of measuring the induction period up to 48h. NOTE1 EN15751 [1] describes a similar test method for oxidation stability determination of pure fatty acid methyl esters and of blends of FAME with petroleum-based diesel containing 2% (V/V) of FAME at minimum. NOTE2 The precision statement of this test method was determined in a Round Robin exercise with induction periods up to 8,5h, thus covering the limit value in EN14214 . Results from precision studies on EN15751 indicate that the precision statement is valid for induction periods up to 48h but not for higher values. NOTE3 Limited studies on EN15751 with EHN (2-ethyl hexyl nitrate) on FAME blends indicated that the stability is reduced to an extent which is within the reproducibility of the test method. It is likely that the oxidation stability of pure FAMEs is also reduced in the presence of EHN when EN14112 is used for testing.
