    Revision of D6839 - 02(2007) Standard Test Method for Hydrocarbon Types, Oxygenated Compounds and Benzene in Spark Ignition Engine Fuels by Gas Chromatography

    (What is a Work Item?)

    Active Standard: D6839 - 18

    Developed by Subcommittee: D02.04.0L | Committee D02 | Contact Staff Manager



    WK39244


    Keywords

    aromatics; gas chromatography; gasoline; hydrocarbon type; multidimensional gas chromatography; naphthenes; olefins; oxygenates; saturates; spark-ignition engine fuels; Aromatic hydrocarbons (AHs); EAA (ethyl-alcohol-aromatic) trap; Gas chromatography (GC)--petroleum products; Hydrogenation catalyst; Multi-dimensional gas chromatography; Naphthenes; Olefins content; Oxygenates; Quality assurance (QA)--petroleum products/applications;

    Rationale

    Subcommittee D.02.04L agreed to start a revision of the D6839 method as there is a strong global interest to harmonize it with the ISO 22854 method which covers the same application. The ISO 22854 method is based on more recent Round Robin and precision data and not only includes a wider range of oxygenates but is being revised to cover higher oxygen percentages up to 3.7% m/m total oxygen content. This will make it applicable for E10 fuels. In addition the method is split into a Part A and B, part B describes a specific methodology using the same configuration as part A to be able to analyze fuels containing ethanol levels between 50 and 85 % (V/V) For the D6839 method this harmonization will make it applicable for all modern types of spark-ignition engine fuels containing higher amounts of ethanol and/or other alcohols & ethers as they are commonly used.
