Designation:D559922Standard Test Method forDetermination of Oxygenates in Gasoline by GasChromatography and Oxygen Selective Flame IonizationDetection1This standard is issued under the fixed designation D5599;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 a gas chromatographic proce-dure for the quantitative determination of organic oxygenatedcompounds in gasoline having a final boiling point not greaterthan 220 C and oxygenates having a boiling point limit of130 C.It is applicable when oxygenates are present in the0.1%to 20%by mass range.1.2 This test method is intended to determine the massconcentration of each oxygenate compound present in a gaso-line.This requires knowledge of the identity of each oxygenatebeing determined(for calibration purposes).However,theoxygen-selective detector used in this test method exhibits aresponse that is proportional to the mass of oxygen.It is,therefore,possible to determine the mass concentration ofoxygen contributed by any oxygenate compound in the sample,whether or not it is identified.Total oxygen content in agasoline may be determined from the summation of theaccurately determined individual oxygenated compounds.Thesummed area of other,uncalibrated or unknown oxygenatedcompounds present,may be converted to a mass concentrationof oxygen and summed with the oxygen concentration of theknown oxygenated compounds.1.3 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.4 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.1.5 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:2D1298 Test Method for Density,Relative Density,or APIGravity of Crude Petroleum and Liquid Petroleum Prod-ucts by Hydrometer MethodD1744 Test Method for Determination of Water in LiquidPetroleum Products by Karl Fischer Reagent(Withdrawn2016)3D4052 Test Method for Density,Relative Density,and APIGravity of Liquids by Digital Density MeterD4175 Terminology Relating to Petroleum Products,LiquidFuels,and LubricantsD4307 Practice for Preparation of Liquid Blends for Use asAnalytical StandardsD6299 Practice for Applying Statistical Quality Assuranceand Control Charting Techniques to Evaluate AnalyticalMeasurement System PerformanceE355 Practice for Gas Chromatography Terms and Relation-shipsE594 Practice for Testing Flame Ionization Detectors Usedin Gas or Supercritical Fluid ChromatographyE1064 Test Method for Water in Organic Liquids by Coulo-metric Karl Fischer TitrationE1510 Practice for Installing Fused Silica Open TubularCapillary Columns in Gas Chromatographs3.Terminology3.1 Definitions:3.1.1 This test method makes reference to common gaschromatographic procedures,terms,and relationships.Detailed1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.04.0L on Gas Chromatography Methods.Current edition approved April 1,2022.Published April 2022.Originallyapproved in 1994.Last previous edition approved in 2018 as D5599 18.DOI:10.1520/D5599-22.2For 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.1definitions of these can be found in Practices E355 and E594and Terminology D4175.3.1.2 check standard,nin QC testing,material having anaccepted reference value(ARV)used to determine the accu-racy of the measurement system.3.1.2.1 DiscussionIn the context of this test method,check s
