About This Item
ASTM D8368 is the ASTM standard for determining totals of aromatic, polyaromatic, and fatty acid methyl esters (FAME) content in diesel fuel using gas chromatography with vacuum ultraviolet absorption spectroscopy detection (GC-VUV). It provides a technical basis for measuring these fuel components in a consistent way, which can support product evaluation, quality control, and compliance-related testing. As a focused analytical method, it helps laboratories generate comparable results for diesel fuel characterization.
ASTM D8368 standard overview
The ASTM D8368 standard addresses a laboratory test method designed to quantify total aromatics, polyaromatics, and FAME content in diesel fuel. Its GC-VUV approach combines gas chromatography separation with vacuum ultraviolet absorption spectroscopy detection, indicating a method intended for detailed compositional analysis rather than general fuel inspection. This makes ASTM D8368 relevant to organizations that need a reliable technical document for assessing fuel composition using an established analytical workflow.
Where is ASTM D8368 used?
This standard is commonly used in fuel testing laboratories, refinery and blending environments, and other settings where diesel fuel composition may need to be measured with analytical precision. It is especially relevant when evaluating diesel fuel samples for aromatic content or FAME levels as part of laboratory testing, specification verification, or incoming material review. ASTM D8368 may also be useful in quality assurance programs that rely on chromatography-based methods to compare fuel batches consistently.
Practical importance of ASTM D8368
ASTM D8368 matters because it gives users a defined method for measuring important diesel fuel constituents that can affect product quality and consistency. By standardizing how totals of aromatics, polyaromatics, and FAME are determined, the method supports more dependable testing results across laboratories and supply chains. For procurement, compliance checks, and routine quality control, ASTM D8368 can help reduce uncertainty and improve confidence in fuel evaluation decisions.
