Designation:D430615An American National StandardStandard Practice forAviation Fuel Sample Containers for Tests Affected by TraceContamination1This standard is issued under the fixed designation D4306;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 This practice2covers the types of and preparation ofcontainers found most suitable for the handling of aviation fuelsamples for the determination of critical properties affected bytrace contamination.1.2 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.3 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.For specificwarning statements,see 5.1,5.2,5.3,5.4,and 5.6.2.Referenced Documents2.1 ASTM Standards:3D2624 Test Methods for Electrical Conductivity of Aviationand Distillate FuelsD3948 Test Method for Determining Water Separation Char-acteristics ofAviation Turbine Fuels by Portable Separom-eterD4057 Practice for Manual Sampling of Petroleum andPetroleum ProductsD4308 Test Method for Electrical Conductivity of LiquidHydrocarbons by Precision MeterD5452 Test Method for Particulate Contamination in Avia-tion Fuels by Laboratory Filtration2.2 SAE Standard:4MAP1794 Aircraft Recommended Practice,Ball-On-Cylinder(Boc)Aircraft Turbine Fuel Lubricity Tester3.Significance and Use3.1 General descriptions for the manual sampling of petro-leum products are given in Practice D4057.However,anumber of aviation fuel properties are established or affectedby trace levels of polar or other compounds.Measurementsignificance therefore requires that the sample containers notadd or adsorb any materials.This practice presents types andpreparations of sampling containers found satisfactory for thedetermination of water separation,copper corrosion,electricalconductivity,thermal stability,lubricity,and trace metal con-tent.An approval procedure for new containers is also given.3.2 Two properties,particulate contamination and free watercontent,involve materials easily removed by any samplingcontainer.These properties should be determined by placingthe sample directly into the measuring apparatus and not usingcontainers to transport the sample to the measuring equipment.3.3 Recommendations in this practice provide guidance forimmediate use and for storage of samples.Immediate useinvolves sample storage for periods less than 24 h.4.Apparatus4.1 Sampling Containers:4.1.1 Epoxy-Coated Containers:4.1.1.1 While generally superior to other coatings,certainepoxy-coatings evolve plasticizers which can adversely affectcritical fuel properties.Because no specification is known todescribe a satisfactory epoxy-coating,6.2 lists an approvalprocedure which can be used to identify a satisfactory coating.4.1.1.2 For initial qualification of new container sources,coated cans should be examined closely to assure that thecoating covers all inside surfaces.If not,the cans should beconsidered the same as tin-plated,soldered side seam cans.4.1.1.3 Epoxy-coated cans are generally considered satis-factory for sampling aviation gasoline.1This practice is under the jurisdiction of ASTM Committee D02 on PetroleumProducts,Liquid Fuels,and Lubricants and is the direct responsibility of Subcom-mittee D02.J0.04 on Additives and Electrical Properties.Current edition approved Oct.1,2015.Published October 2015.Originallyapproved in 1984.Last previous edition approved 2013 as D4306 13.DOI:10.1520/D4306-15.2The detailed data on which this practice is based may be found in SAE PracticeMAP1794 and three research reports.Supporting data have been filed at ASTMInternational Headquarters and may be obtained by requesting Research ReportsRR:D02-1169,RR:D02-1142,and RR:D02-1504.3For 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.4Available from Society of Automotive Engineers(SAE),400 CommonwealthDr.,Warrendale,PA 15096-0001,http:/www.sae.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 4.1.2 Borosilicate(Hard)Glass BottlesAmber colored orbottles covered with an opaque material such as aluminum foilare preferred to avoid possible reactions with sunlight.4.1.3 Polytetrafluoroethylene(PTFE)BottlesBlack
