本文件规定了脂肪酸甲酯（FAME）在110°C下的氧化稳定性测定方法，通过测量诱导期长达48小时。 对于高于8.5h的诱导期，本方法的精度说明不包括精度。 注1 EN 15751[1]描述了测定氧化稳定性的类似试验方法 纯脂肪酸甲酯和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（2-乙基己基硝酸酯）在FAME共混物上的有限研究表明，稳定性降低到试验方法再现性范围内的程度。很可能纯FAMEs的氧化稳定性也 当使用EN 14112进行试验时，在存在EHN的情况下降低。 注3:在本文件中，术语“%（V/V）”用于表示体积分数。

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.
