Designation:D815017Standard Test Method forDetermination of Organic Chloride Content in Crude Oil byDistillation Followed by Detection Using Combustion IonChromatography1This standard is issued under the fixed designation D8150;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 organicchloride(above 1 g/g organically-bound chlorine)in crudeoils,using distillation and combustion ion chromatography.1.2 This test method involves the distillation of crude oiltest specimens to obtain a naphtha fraction prior to chloridedetermination.The chloride content of the naphtha fraction ofthe whole crude oil can thereby be obtained.See Section 5regarding potential interferences.1.3 The test procedure covers the determination of organicchloride in the washed naphtha fraction of crude oil bycombustion ion chromatography.Other halides can be deter-mined but are not included in the precision statement of the testmethod.1.4 The values stated in SI units are to be regarded asstandard.The preferred concentration units are micrograms ofchloride per gram of sample.1.4.1 ExceptionThe values given in parentheses are forinformation only.1.5 WarningMercury has been designated by many regu-latory agencies as a hazardous material that can cause centralnervous system,kidney and liver damage.Mercury,or itsvapor,may be hazardous to health and corrosive to materials.Caution should be taken when handling mercury and mercurycontaining products.See the applicable product MaterialSafety Data Sheet(MSDS)for details and EPAs websitehttp:/www.epa.gov/mercury/faq.htmfor additional informa-tion.Users should be aware that selling mercury and/ormercury containing products into your state or country may beprohibited by law.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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.7 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:2D86 Test Method for Distillation of Petroleum Products andLiquid Fuels at Atmospheric PressureD1193 Specification for Reagent WaterD1298 Test Method for Density,Relative Density,or APIGravity of Crude Petroleum and Liquid Petroleum Prod-ucts by Hydrometer MethodD4052 Test Method for Density,Relative Density,and APIGravity of Liquids by Digital Density MeterD4057 Practice for Manual Sampling of Petroleum andPetroleum ProductsD4177 Practice for Automatic Sampling of Petroleum andPetroleum ProductsD4929 Test Method for Determination of Organic ChlorideContent in Crude OilD6299 Practice for Applying Statistical Quality Assuranceand Control Charting Techniques to Evaluate AnalyticalMeasurement System PerformanceD6300 Practice for Determination of Precision and BiasData for Use in Test Methods for Petroleum Products andLubricantsD6708 Practice for Statistical Assessment and Improvementof Expected Agreement Between Two Test Methods thatPurport to Measure the Same Property of a MaterialE288 Specification for Laboratory Glass Volumetric FlasksE969 Specification for Glass Volumetric(Transfer)Pipets1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.03 on Elemental Analysis.Current edition approved Oct.1,2017.Published November 2017.DOI:10.1520/D8150-17.2For 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.Copyright 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.1 3.Summary of Test Method3.1 DistillationA crude oil distillation is performed toobtain the naphtha cut at 204 C(400 F).The distillationmethod was adapted from Test Method D86 for the distillationof petroleum products as well as Test Method D4929 fordetermination of organic chloride content in crude o
