Designation:D739811Standard Test Method forBoiling Range Distribution of Fatty Acid Methyl Esters(FAME)in the Boiling Range from 100 to 615C by GasChromatography1This standard is issued under the fixed designation D7398;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 fatty acid methyl esters(FAME).This testmethod is applicable to FAMES(biodiesel,B100)having aninitial boiling point greater than 100C and a final boiling pointless than 615C at atmospheric pressure as measured by thistest method.1.2 The test method can also be applicable to blends ofdiesel and biodiesel(B1 through B100),however precision forthese samples types has not been evaluated.1.3 The test method is not applicable for analysis ofpetroleum containing low molecular weight components(forexample naphthas,reformates,gasolines,crude oils).1.4 Boiling range distributions obtained by this test methodare not equivalent to results from low efficiency distillationsuch as those obtained with Test Method D86 or D1160,especially the initial and final boiling points.1.5 This test method uses the principles of simulated distil-lation methodology.See Test Methods D2887,D6352,andD7213.1.6 The values stated in SI units are to be regarded asstandard.The values given in parentheses are for informationonly.1.7 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)D4626 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 ChromatographyD6751 Specification for Biodiesel Fuel Blend Stock(B100)for Middle Distillate FuelsD7213 Test Method for Boiling Range Distribution of Pe-troleum Distillates in the Boiling Range from 100 C to615 C by Gas ChromatographyE355 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 Chromatographs3.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 E1510.1This 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 Oct.1,2011.Published November 2011.Originallyapproved in 2007.Last previous edition approved in 2007 as D7398-07.DOI:10.1520/D7398-11.2For 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.*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 3.1.2 biodiesel,nfuel composed of mono-alkyl esters oflong chain fatty acids derived from vegetable oils or animalfats,designated B100.3.2 Definitions of Terms Specific to This Standard:3.2.1 area slice,narea resulting from the integration of thechromatographic detector signal within a specified retentiontime interval.In area slice mode(6.4.2),peak detectionparameters are bypassed and the detector signal integral isrecorded as area slices of consecutive,fixed duration timeintervals.3.2.2 atmosphericequivalenttemperature(AET),ntemperature converted from the measured vapor tempera-ture obtained at sub-ambient pressure to atmospheric equiva-lent temperature(AET)corresponding to the equivalent boilingpoint at atmospheric pressure,101.3 kPa(760 mm Hg),TheAET is the expected distillate temperature if the distillationwas performed at atmospheric pressure and there was nothermal decomposition.3.2.3 corrected area slice,narea slice corrected for base-line offset,by subtraction of the exactly corresponding areaslice in a previously recorded blank(non-sample)analy
