| Significance and Use | ||||||||||||||||||||||||||||||
|
5.1Biodiesel is a blendstock commodity primarily used as a value-added blending component with diesel fuel. 5.2This test method is applicable for quality control in the production and distribution of diesel fuel and biodiesel blends containing FAME. |

| 1. Scope | ||||||||||||||||||||||||||||||
|
1.1This test method covers the determination of the content of fatty acid methyl esters (FAME) biodiesel in diesel fuel oils. It is applicable to concentrations from 1.00 % to 20 % by volume (see Note 1). This procedure is applicable only to FAME. Biodiesel in the form of fatty acid ethyl esters (FAEE) will cause a negative bias. Note 1:Using the proper ATR sample accessory, the range may
be expanded from 1 % to 100 % by volume, however precision data is
not available above 20 % by volume.
1.2The values stated in SI units of measurement are to be regarded as the standard. The values given in parentheses are for information only. 1.3This 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. 1.4This 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. |
