This document 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 48 h. For induction periods higher than 8,5 h the precision is not covered by the precision statement of this method. NOTE 1 EN 15751 [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. NOTE 2 Limited studies on EN 15751 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 EN 14112 is used for testing. NOTE 3 For the purposes of this document, the term ''% (V/V)'' is used to represent the volume fraction.

本文件规定了在110℃下测定脂肪酸甲酯（FAME）氧化稳定性的方法，通过测量长达48小时的诱导期。 对于高于 8.5 小时的诱导期，该方法的精度声明不涵盖精度。 注 1 EN 15751 [1] 描述了一种类似的测试方法，用于测定纯脂肪酸甲酯以及 FAME 与至少含有 2% (V/V) FAME 的石油基柴油的混合物。 注 2：EN 15751 与 EHN（硝酸 2-乙基己酯）对 FAME 混合物的有限研究表明，稳定性降低到测试方法可重复性范围内的程度。 当使用 EN 14112 进行测试时，纯 FAME 的氧化稳定性在 EHN 存在的情况下也可能会降低。 注3：就本文件而言，术语“%（V/V）”用于表示体积分数。
