Designation:D779813Standard Test Method forBoiling Range Distribution of Petroleum Distillates withFinal Boiling Points up to 538C 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.Scope1.1 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 538C orlower at atmospheric pressure as measured by this test method.The difference between the initial boiling point and the finalboiling point shall be greater than 55C.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 1015 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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D86 Test Method for Distillation of Petroleum Products atAtmospheric 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 FactorsD6352 Test Method for Boiling Range Distribution of Pe-troleum Distillates in Boiling Range from 174 C to 700C 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 GasChromatographyD7169 Test Method for Boiling Point Distribution ofSamples with Residues Such as Crude Oils and Atmo-spheric and Vacuum Residues by High Temperature GasChromatographyE355 Practice for Gas Chromatography Terms and Relation-shipsE594 Practice for Testing Flame Ionization Detectors Usedin Gas or Supercritical Fluid ChromatographyE1510 Practice for Installing Fused Silica Open TubularCapillary Columns in Gas Chromatographs1This 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 Jan.1,2013.Published April 2013.DOI:10.1520/D7798-13.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.Terminology3.1 Definitions:3.1.1 This test method makes reference to many commongas chromatographic procedures,terms,and relationships.Detailed definitions of these can be found in Practices E355,E594,and E1510.3.1.2 area slice,nin gas chromatography,the area,result-ing from the integration of the chromatographic detectorsignal,within a specified retention time interval.3.1.3 corrected area slice,nin gas chromatography,anarea slice corrected for baseline offset,by subtraction of thecorresponding area slice in a previously recorded blank(non-sample)analysis.3.1.4 cumulativecorrectedarea,ningaschromatography,the accumulated sum of corrected area slicesfrom the beginning of the analysis through to
