ISO/TS 17307:2016建立了通过气相色谱法和使用外标测定脂肪酸甲酯(FAME)中总甲酯含量的方法。该方法适用于含有C6和C26之间酯的生物柴油。该方法允许验证总酯含量大于96.5%(m/m)。 注1该方法还允许测定FAEE中的总乙酯含量，但尚未确定其精密度。 本技术规范不确定亚麻酸或多不饱和烷基酯含量。替代技术，例如分别为EN 14103[1]和EN 15779[2]，可用于此。 注2就本技术规范而言，术语“%(m/m)”用于表示质量分数μ。

ISO/TS 17307:2016 establishes a method for determining the total methyl ester content in fatty acid methyl ester (FAME) by gas chromatography and using an external standard. The method is suitable for biodiesel which contains esters between C6 and C26. This method allows verifying that the total ester content is greater than 96,5 % (m/m). NOTE 1 The method also allows determination of the total ethyl ester content in FAEE, but precision for this has not been established. This Technical Specification does not determine the linolenic nor the poly-unsaturated alkyl ester content. Alternative techniques, such as EN 14103^[1] and EN 15779^[2], respectively, are available for this. NOTE 2 For the purposes of this Technical Specification, the term "% (m/m)" is used to represent the mass fraction, μ.
