ASTM WK69798

    Revision of D7169 - 18 Standard Test Method for Boiling Point Distribution of Samples with Residues Such as Crude Oils and Atmospheric and Vacuum Residues by High Temperature Gas Chromatography

    (What is a Work Item?)

    Active Standard: D7169 - 19

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



    WK69798


    Keywords

    boiling point distribution; crude oils; cut point intervals; distillation residues; lubricants; residues; simulated distillation;;

    Rationale

    A member of D0204-H has suggested there is a specified condition in the execution of the method that is too onerous in the execution of the method. Section 15.3 requires that for every sample a duplicate sample is to be carried out. The sentence is modified by checking the sample solvent blank profile and overlaying it over the sample profile. The solvent blank chromatogram should very closely match the chromatogram of solvent +sample.
