本欧洲标准规定了通过测量燃料的诱导期达48小时来确定柴油发动机燃料的氧化稳定性的试验方法。该方法适用于旨在用作纯生物燃料或柴油燃料混合成分的脂肪酸甲酯（FAME），以及至少含有2％（V/V）FAME的FAME与柴油混合物的混合物。 注1 EN 14112 [1]描述了纯脂肪酸甲酯的氧化稳定性测定的类似试验方法（见本欧洲标准引言）。 注2:对于高于48小时的诱导期，精度不在本方法的精确度范围内。相关燃料标准的极限值完全在本试验方法的范围内。 注3:十六烷值改进剂的存在可以降低由该测试方法确定的氧化稳定性。然而，使用EHN（2-乙基己基硝酸酯）的有限研究表明，稳定性降低到在测试方法的再现性之内的程度。 注4为了本欧洲标准的目的，术语“％（V/V）”用于表示材料的体积分数（φ）

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) of FAME at minimum. NOTE 1 EN 14112 [1] describes a similar test method for oxidation stability determination of pure fatty acid methyl esters (see the Introduction to this European Standard). NOTE 2 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. NOTE 3 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. NOTE 4 For the purposes of this European Standard, the term "% (V/V)" is used to represent the volume fraction (φ) of a material.
