Designation:D709610Standard Test Method forDetermination of the Boiling Range Distribution of Gasolineby Wide-Bore Capillary Gas Chromatography1This standard is issued under the fixed designation D7096;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 gasoline and liquid gasoline blendingcomponents.It is applicable to petroleum products and frac-tions with a final boiling point of 280C(536F)or lower,asmeasured by this test method.1.2 This test method is designed to measure the entireboiling range of gasoline and gasoline components with eitherhigh or low vapor pressure and is commonly referred to asSimulated Distillation(SimDis)by gas chromatographers.1.3 This test method has been validated for gasoline con-taining ethanol.Gasolines containing other oxygenates are notspecifically excluded,but they were not used in the develop-ment of this test method.1.4 This test method can estimate the concentration ofn-pentane and lighter saturated hydrocarbons in gasoline.1.5 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.5.1 Results in degrees Fahrenheit can be obtained bysimply substituting Fahrenheit boiling points in the calculationof the boiling point-retention time correlation.1.6 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 PressureD2421 Practice for Interconversion of Analysis of C5andLighter Hydrocarbons to Gas-Volume,Liquid-Volume,orMass BasisD3700 Practice for Obtaining LPG Samples Using a Float-ing Piston CylinderD3710 Test Method for Boiling Range Distribution of Gaso-line and Gasoline Fractions by Gas Chromatography(Withdrawn 2014)3D4057 Practice for Manual Sampling of Petroleum andPetroleum ProductsD4307 Practice for Preparation of Liquid Blends for Use asAnalytical StandardsD4626 Practice for Calculation of Gas ChromatographicResponse FactorsD4814 Specification for Automotive Spark-Ignition EngineFuelD4815 Test Method for Determination of MTBE,ETBE,TAME,DIPE,tertiary-Amyl Alcohol and C1to C4Alco-hols in Gasoline by Gas ChromatographyD5191 Test Method for Vapor Pressure of Petroleum Prod-ucts(Mini Method)D5599 Test Method for Determination of Oxygenates inGasoline by Gas Chromatography and Oxygen SelectiveFlame Ionization DetectionD6300 Practice for Determination of Precision and BiasData for Use in Test Methods for Petroleum Products andLubricantsE594 Practice for Testing Flame Ionization Detectors Usedin Gas or Supercritical Fluid ChromatographyE1510 Practice for Installing Fused Silica Open TubularCapillary Columns in Gas Chromatographs3.Terminology3.1 Definitions:3.1.1 area slice,narea under a chromatogram within aspecified retention time interval.3.1.2 final boiling point(FBP),nthe point at which acumulative volume count equal to 99.5%of the total volumecounts under the chromatogram is obtained.1This 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 Feb.15,2010.Published May 2010.Originallyapproved in 2005.Last previous edition approved in 2005 as D709605.DOI:10.1520/D7096-10.2For 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 States1 3.1.3 initial boiling point(IBP),nthe point at which acumulative volume count equal to 0.5%of the total volumecounts under the chromatogram is obtained.3.1.4 relative volume response factor(RVRF),nthe vol-ume response factor(see 3.1.8)of a component i relative to thevolume response factor of n-heptane.3.1.5 slice time,nthe retention time at the end of a givenarea slice.3.1.6 slice width,nthe fixed duration(1 s,or less)of theretention time intervals into which the chromatogram is di-vided.It is determined from the reciprocal of the frequencyused in the acquisition of data.3.1.7 volume count,nthe product of a slice area(or anarea un
