Designation:D382812aStandard Test Methods forFlash Point by Small Scale Closed Cup Tester1This standard is issued under the fixed designation D3828;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.INTRODUCTIONThese small scale flash point methods are generally used for testing a sample at a specifictemperature where the specimen being tested and the airvapor mixture above it are close to thermalequilibrium.Test Method D3941 covers other flash point equipment operated at a specific temperature.Flash point values are a function of the apparatus design,the condition of the apparatus used,andthe operational procedure carried out.Flash point can therefore only be defined in terms of a standardtest method,and no general valid correlation can be guaranteed between results obtained by differenttest methods,or with test apparatus different from that specified.1.Scope*1.1 These test methods cover procedures for flash pointtests,within the range of 30 to 300C,of petroleum productsand biodiesel liquid fuels,using a small scale closed cup tester.The procedures may be used to determine,whether a productwill or will not flash at a specified temperature(flash/no flashMethod A)or the flash point of a sample(Method B).Whenused in conjunction with an electronic thermal flash detector,these test methods are also suitable for flash point tests onbiodiesels such as fatty acid methyl esters(FAME).1.2 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.1.3 This standard should be used to measure and describethe properties of materials,products,or assemblies in responseto heat and flame under controlled laboratory conditions andshould not be used to describe or appraise the fire hazard orfire risk of materials,products,or assemblies under actual fireconditions.However,results of this test may be used aselements of a fire risk assessment which takes into account allof the factors which are pertinent to an assessment of the firehazard of a particular end use.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 and health practices and determine the applica-bility of regulatory limitations prior to use.Warning statementsappear throughout.See also the Material Safety Data Sheets forthe product being tested.2.Referenced Documents2.1 ASTM Standards:2D3941 Test Method for Flash Point by the EquilibriumMethod With a Closed-Cup ApparatusD4057 Practice for Manual Sampling of Petroleum andPetroleum ProductsD4177 Practice for Automatic Sampling of Petroleum andPetroleum ProductsD6299 Practice for Applying Statistical Quality Assuranceand Control Charting Techniques to Evaluate AnalyticalMeasurement System PerformanceD6708 Practice for Statistical Assessment and Improvementof Expected Agreement Between Two Test Methods thatPurport to Measure the Same Property of a MaterialE300 Practice for Sampling Industrial ChemicalsE1137/E1137M Specification for Industrial Platinum Resis-tance Thermometers2.2 ISO Standards:3Guide 34 Quality Systems Guidelines for the Production ofReference MaterialsGuide 35 Certification of Reference MaterialsGeneral and1These test methods are under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.08 on Volatility.Current edition approved Nov.1,2012.Published February 2013.Originallyapproved in 1979.Last previous edition approved in 2012 as D382812.DOI:10.1520/D3828-12A.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.3Available 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 Statistical PrinciplesEN ISO 3679 Determination of Flash PointRapid Equilib-rium Closed Cup MethodEN ISO 3680 Determination of Flash/No FlashRapidEquilibrium Closed Cup MethodISO 60751 Industrial platinum resistance thermometers andplatinum temperature sensors2.3 Energy Institute Standards:4IP 523 Determination of flash point Rapid equilibriumclosed cup methodIP 524 Determination of flash/no flash Rapid equilibriumclosed cup method3.Terminology3.1 Definitions:3.1.1 equilibrium,nin flash point test methods,the condi-tion where t
