Designation:D709417aStandard Test Method forFlash Point by Modified Continuously Closed Cup(MCCCFP)Tester1This standard is issued under the fixed designation D7094;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 flashpoint of fuels including diesel/biodiesel blends,lube oils,solvents,and other liquids by a continuously closed cup testerutilizing a specimen size of 2 mL,cup size of 7 mL,with aheating rate of 2.5 C per minute.1.1.1 Apparatus requiring a specimen size of 1 mL,cup sizeof 4 mL,and a heating rate of 5.5 C per minute must be runaccording to Test Method D6450.1.2 This flash point test method is a dynamic method anddepends on definite rates of temperature increase.It is one ofthe many flash point test methods available and every flashpoint test method,including this one,is an empirical method.NOTE1Flash point values are not a constant physical chemicalproperty of materials tested.They are a function of the apparatus design,the condition of the apparatus used,and the operational procedure carriedout.Flash point can,therefore,only be defined in terms of a standard testmethod and no general valid correlation can be guaranteed between resultsobtained by different test methods or where different test apparatus isspecified.1.3 This test method utilizes a closed but unsealed cup withair injected into the test chamber.1.4 This test method is suitable for testing samples with aflash point from 35 C to 225 C.NOTE2Flash point determinations below 35 C and above 225 Cmay be performed;however,the precision has not been determined belowand above these temperatures.1.5 If the users specification requires a defined flash pointmethod other than this method,neither this method nor anyother test method should be substituted for the prescribed testmethod without obtaining comparative data and an agreementfrom the specifier.1.6 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.Temperatures are in degrees Celsius,pressure inkilo-Pascals.1.7 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.For specific warning statements,see 7.2,8.5,and 10.1.2.1.8 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:2D93 Test Methods for Flash Point by Pensky-MartensClosed Cup TesterD4057 Practice for Manual Sampling of Petroleum andPetroleum ProductsD4177 Practice for Automatic Sampling of Petroleum andPetroleum ProductsD6450 Test Method for Flash Point by Continuously ClosedCup(CCCFP)TesterD6708 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 Chemicals2.2 ISO Standards:3ISO Guide 34 Quality Systems Guidelines for the Produc-tion of Reference MaterialsISO Guide 35 Certification of Reference MaterialsGeneraland Statistical Principles3.Terminology3.1 Definitions:1This test method is 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 Dec.1,2017.Published February 2018.Originallyapproved in 2004.Last previous edition approved in 2017 as D7094 17.DOI:10.1520/D7094-17A.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 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 3.1.1 dynamic,adjthe condition where the vapor abovethe test specimen
