本文件的目的是描述用于测定用于掺入柴油的脂肪酸甲酯（FAME）中酯含量的方法。它还可以测定亚麻酸甲酯的含量。它允许验证FAME的酯含量大于90％（m/m），亚麻酸含量在1％（m/m）至15％（m/m）之间。 该方法适用于含有C6和C24之间的甲酯的FAME。 注意为了本欧洲标准的目的，术语“％（m/m）和％（v/v）”用于分别表示质量和体积分数。 警告 - 使用此方法可能涉及危险设备，材料和操作。该方法并不旨在解决与其使用相关的所有安全问题，但用户有责任在使用前搜索和建立适当的安全和健康实践并确定法规限制的适用性

The purpose of this document is to describe a procedure for the determination of the ester content in fatty acid methyl esters (FAME) intended for incorporation into diesel oil. It also allows determining the linolenic acid methyl ester content. It allows verifying that the ester content of FAME is greater than 90 % (m/m) and that the linolenic acid content is between 1 % (m/m) and 15 % (m/m). This method is suitable for FAME which contains methyl esters between C6 and C24. NOTE 1 For the purposes of this document, the terms "% (m/m)" and "% (v/v)" are used to represent respectively the mass and volume fractions. NOTE 2 This method was elaborated for FAME samples from usual raw material. For FAME sample from unidentified raw material, a solution of the test sample should be prepared without any internal standard addition, in order to verify the absence of natural nonadecanoic acid methyl ester. NOTE 3 The distribution off fatty acid methyl esters is given in Annex C. WARNING - The use of this method may involve hazardous equipment, materials and operations. This method does not purport to address to all of the safety problems associated with its use, but it is the responsibility of the user to search and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
