About This Item
ASTM D7806 is a test method for measuring biodiesel content, specifically fatty acid methyl ester and triglyceride content, in diesel fuel oil using mid-infrared spectroscopy with an FTIR transmission method. It supports consistent fuel evaluation by giving laboratories and fuel suppliers a standardized way to assess key blend components that can affect product quality and specification compliance. As a recognized ASTM standard, it is useful wherever reliable, repeatable analysis of diesel fuel composition is needed.
Overview of ASTM D7806
The ASTM D7806 standard provides a technical framework for determining biodiesel-related components in diesel fuel oil by mid-infrared spectroscopy. Its focus is on FTIR transmission measurement, which is commonly used for analytical testing where rapid and standardized results are important. This standard helps define a controlled approach for assessing fatty acid methyl ester and triglyceride content, making it relevant to laboratories and organizations that need a consistent method for fuel characterization and compliance-oriented testing.
Common use cases of ASTM D7806
This standard is commonly used in fuel testing workflows where diesel fuel oil must be evaluated for biodiesel content. It is relevant to quality control labs, incoming fuel verification, and product evaluation programs that rely on FTIR-based analysis. ASTM D7806 may also support procurement checks, batch comparison, and routine monitoring of diesel blends where fatty acid methyl ester and triglyceride levels are of interest. It is especially useful when a standardized mid-infrared method is needed for repeatable results.
Benefits of using ASTM D7806
Using ASTM D7806 helps promote consistent testing practices for diesel fuel oil analysis. It supports better comparability between laboratories, clearer quality control decisions, and more reliable documentation of biodiesel-related content. For organizations handling fuel procurement, blending, or verification, the standard can reduce ambiguity in testing methods and improve confidence in reported results. ASTM D7806 is also valuable for aligning internal testing with an established ASTM standard.
