ISO/TS 17306:2016建立了通过气相色谱法定量测定由任何原料（包括椰子油或棕榈油和动物脂肪）生产的生物柴油中游离甘油、单酰甘油、二酰甘油、三酰甘油和总甘油的方法。它不适用于蓖麻油的生物柴油。 在大多数实际情况下，生物柴油基于脂肪酸甲酯（FAME）。在该检测方法的精密度研究中也使用了这些数据。没有迹象表明该方法不适用于其他酯类型，但精密度尚未测定或比较。 注:出于本技术规范的目的，术语“%(m/m)”用于表示质量分数μ。

ISO/TS 17306:2016 establishes a methodology for quantitative determination of free glycerol, mono-, di-, triacylglycerols and total glycerol by gas chromatography in biodiesel produced from any raw material including coconut or palm oil and animal fat. It is not applicable for biodiesel from castor oil. In most actual cases, biodiesel is based on fatty acid methyl esters (FAME). These have also been used during the precision study for this test method. There is no indication that the methodology does not apply to other ester types, but the precision has not been determined nor compared. NOTE For the purposes of this Technical Specification, the term "% (m/m)" is used to represent the mass fraction, μ.
