EN 14112	Fat and oil derivatives - Fatty Acid Methyl Esters (FAME) - Determination of oxidation stability (accelerated oxidation test)

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.

本文件規定了在110℃下測定脂肪酸甲酯（FAME）氧化穩定性的方法，通過測量長達48小時的誘導期。對于高于 8.5 小時的誘導期，該方法的精度聲明不涵蓋精度。注 1 EN 15751 [1] 描述了一種類似的測試方法，用于測定純脂肪酸甲酯以及 FAME 與至少含有 2% (V/V) FAME 的石油基柴油的混合物。注 2：EN 15751 與 EHN（硝酸 2-乙基己酯）對 FAME 混合物的有限研究表明，穩定性降低到測試方法可重復性范圍內的程度。當使用 EN 14112 進行測試時，純 FAME 的氧化穩定性在 EHN 存在的情況下也可能會降低。注3：就本文件而言，術語“%（V/V）”用于表示體積分數。
