Designation:D750015Standard Test Method forDetermination of Boiling Range Distribution of Distillatesand Lubricating Base Oilsin Boiling Range from 100 C to735 C by Gas Chromatography1This standard is issued under the fixed designation D7500;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 by capillary gaschromatography using flame ionization detection.This stan-dard test method has been developed through the harmoniza-tion of two test methods,Test Method D6352 and IP 480.Asboth of these methods cover the same scope and include verysimilar operating conditions,it was agreed that a singlestandard method would benefit the global simulated distillationcommunity.1.2 This test method is not applicable for the analysis ofpetroleum or petroleum products containing low molecularweight components(for example naphthas,reformates,gasolines,diesel).Components containing hetero atoms(forexample alcohols,ethers,acids,or esters)or residue are not tobe analyzed by this test method.See Test Methods D7096,D2887,or D7213 for possible applicability to analysis of thesetypes of materials.This method is also not suitable for samplesthat will not elute completely from the gas chromatographiccolumn,leaving residues.For such samples as crude oils andresidues,see Test Methods D5307 and D7169.1.3 This test method is applicable to distillates with initialboiling points above 100 C and final boiling points below735 C(carbon 110);for example,distillates(IBP 100 C),base oils and lubricating base stocks.1.4 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.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 ChromatographyD5307 Test Method for Determination of Boiling RangeDistribution of Crude Petroleum by Gas Chromatography(Withdrawn 2011)3D6352 Test Method for Boiling Range Distribution of Pe-troleum Distillates in Boiling Range from 174 C to 700C by Gas ChromatographyD7096 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 GasChromatographyD7213 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 Chromatographs2.2 ISO Standard:4ISO 3170 Petroleum Liquids Manual Sampling1This 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 July 1,2015.Published July 2015.Originally approvedin 2008.Last previous edition approved in 2014 as D7500 14.DOI:10.1520/D7500-15.2For 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.4Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.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.Terminology3.1 DefinitionsThis test method makes reference to manycommon gas chromatographic procedures,terms,and relation-ships.For definitions of these terms used in this test method,refer to Practices E355,E594,and E1510.3.2 Definitions of Terms Specific to This Standard:3.2.1 area slice,nthe area resulting from the integration ofthe chromatographic detector signal within a specified reten-tion time interval.In area slice mode(see 6.4.1),peak detectionparameters are bypas
