About This Item
ASTM D5986 is the standard test method for determining oxygenates, benzene, toluene, C8–C12 aromatics, and total aromatics in finished gasoline by gas chromatography/Fourier transform infrared spectroscopy. It is used to support accurate fuel analysis where aromatic and oxygenate content must be measured with consistency. By defining a recognized test approach, this ASTM standard helps labs, refiners, and quality teams evaluate gasoline composition for technical review and compliance-related decisions.
ASTM D5986 standard overview
This ASTM standard provides a test method focused on finished gasoline and the measurement of selected fuel components, including oxygenates and key aromatic fractions. The title indicates a combined analytical approach using gas chromatography and Fourier transform infrared spectroscopy, which is intended to characterize specific compounds and overall aromatic content. ASTM D5986 is therefore relevant to laboratories that need a controlled, repeatable method for fuel composition analysis and reporting.
Where is ASTM D5986 used?
ASTM D5986 is commonly used in fuel testing laboratories, petroleum quality control workflows, and analytical settings that examine finished gasoline. It supports evaluation of gasoline samples where oxygenate content and aromatic species such as benzene, toluene, and C8–C12 aromatics are important. The standard is also useful in procurement and specification verification when buyers, sellers, or third-party labs need a consistent method for measuring finished fuel composition.
Practical importance of ASTM D5986
In practice, ASTM D5986 helps organizations compare gasoline results using a recognized testing framework rather than ad hoc methods. That supports consistency in laboratory reporting, product evaluation, and quality control decisions. It can also reduce uncertainty when checking conformance to internal specifications or contractual requirements. For teams handling finished gasoline, the standard offers a reliable basis for measuring targeted aromatic and oxygenate content in a way that supports traceable technical review.
