This European Standard describes a procedure for the determination of steryl glycosides (SG) in pure fatty acid methyl ester (FAME, often referred to as biodiesel). This method is suitable for the analysis of FAME prepared from vegetable oils. It is possible to quantify the SG content in homogenous samples as well as in samples where the SG started to precipitate. WARNING The use of this standard can involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of users of this standard to take appropriate measures to ensure the safety and health of personnel prior to application of the standard, and fulfil statutory and regulatory requirements for this purpose.
