ASTM International Standard Test Method for Analysis of Biodiesel Products by Gas Chromatography-Mass Spectrometry ASTM E2997-16

1.1 This test method covers the analysis and identification of the fatty acid methyl esters (FAMEs) and petroleum distillate components of biodiesel products. 1.2 This test method is suitable for identifying the components of biodiesel products in extracts of debris samples or in liquid samples. 1.3 The identification of a specific source of the FAMEs or the proportion of the blend of biodiesel requires additional analysis and is beyond the scope of this test method. 1.4 This test method cannot replace the requisite knowledge, skills, or abilities acquired through appropriate education, training, and experience and should be used in conjunction with sound professional judgment. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 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 and health practices and determine the applicability of regulatory limitations prior to use.
