Scope

1.1 This test method covers the quantitative determination of total monoglyceride, total diglyceride, total triglyceride, and free and total glycerin in B-100 methyl esters by gas chromatography. The range of quantitation for monoglyceride is 0.009 % to 0.77860 % by mass, for diglyceride is 0.092353 % to 0.54475 % by mass, and for triglyceride is 0.00092857 % to 1.3881 % by mass. The range of quantitation for free glycerin is 0.0005714 % to 0.019533 % by mass and for total glycerin from 0.0090714 % to 0.42767 % by mass. This procedure is not applicable to vegetable oil methyl esters obtained from lauric oils, such as coconut oil and palm kernel oil. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
