Designation:D779820Standard Test Method forBoiling Range Distribution of Petroleum Distillates withFinal Boiling Points up to 538 C by Ultra Fast GasChromatography(UF GC)1This standard is issued under the fixed designation D7798;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This test method covers the determination of the boilingrange distribution of petroleum products and biodieselformulations,B5,B10,and B20.It is applicable to petroleumdistillates having a final boiling point not greater than 538 Cor lower at atmospheric pressure as measured by this testmethod.The difference between the initial boiling point and thefinal boiling point shall be greater than 55 C.1.2 The test method is not applicable for analysis ofpetroleum distillates containing low molecular weight compo-nents(for example naphthas,reformates,gasolines,full rangecrude oils).Materials containing heterogeneous mixtures(forexample,alcohols,ethers,acids or esters,except biodiesels)orresidue are not to be analyzed by this test method.See TestMethods D3710,D7096,D6352,or D7169.1.3 This test method uses the principles of simulated distil-lation methodology.This test method uses gas chromato-graphic components that allow the entire analysis from sampleto sample to occur in 5 min or less.In these instruments thecolumn is heated directly at rates 10 to 15 times that of aconventional gas chromatograph and thus the analysis time isreduced from sample to sample.1.4 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.4.1 ExceptionAppendix X1 includes temperatures inFahrenheit for information only.1.5 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D86 Test Method for Distillation of Petroleum Products andLiquid Fuels at Atmospheric PressureD1160 Test Method for Distillation of Petroleum Products atReduced PressureD2887 Test Method for Boiling Range Distribution of Pe-troleum Fractions by Gas ChromatographyD2892 Test Method for Distillation of Crude Petroleum(15-Theoretical Plate Column)D3710 Test Method for Boiling Range Distribution of Gaso-line and Gasoline Fractions by Gas Chromatography(Withdrawn 2014)3D4626 Practice for Calculation of Gas ChromatographicResponse FactorsD6300 Practice for Determination of Precision and BiasData for Use in Test Methods for Petroleum Products,Liquid Fuels,and LubricantsD6352 Test Method for Boiling Range Distribution of Pe-troleum Distillates in Boiling Range from 174 C to700 C by Gas ChromatographyD6708 Practice for Statistical Assessment and Improvementof Expected Agreement Between Two Test Methods thatPurport to Measure the Same Property of a MaterialD7096 Test Method for Determination of the Boiling RangeDistribution of Gasoline by Wide-Bore Capillary GasChromatography1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.04.0H on Chromatographic Distribution Methods.Current edition approved Oct.1,2020.Published November 2020.Originallyapproved in 2013.Last previous edition approved in 2015 as D7798 15.DOI:10.1520/D7798-20.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3The last approved version of this historical standard is referenced onwww.astm.org.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1D7169 Test Method for Boiling Point Distribution ofSamples with Residues Such as Crude Oils and Atmo-spheric and Vacuum Residues by High Temperature GasChromatographyE355 Practi
