Designation:D3143/D3143M13Standard Test Method forFlash Point of Cutback Asphalt with Tag Open-CupApparatus1This standard is issued under the fixed designation D3143/D3143M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method covers the determination of flash pointsby the Tag Open-Cup Apparatus of cutback asphalts havingflash points of less than 93C 200F.NOTE1Specifications commonly designate the Cleveland Open Cup(Test Method D92IP 36)Method for asphalt cements and cutbackasphalts having flash points above 79C 175F.NOTE2This procedure follows in general the procedure outlined inTest Method D1310,but is restricted to cutback asphalt having flash pointsof less than 93C 200F.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.3 WarningMercury has been designated by the UnitedStates Environmental Protection Agency and many state agen-cies as a hazardous material that can cause central nervoussystem,kidney and liver damage.Mercury,or its vapor,may behazardous to health and corrosive to materials.Caution shouldbe taken when handling mercury and mercury containingproducts.See the applicable Material Safety Data Sheet(MSDS)for details and EPAs website(http:/www.epa.gov/mercury/index.htm)for additional information.Users shouldbe aware that selling mercury and/or mercury containingproducts into your state may be prohibited by state law.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.1.5 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.2.Referenced Documents2.1 ASTM Standards:2D92 Test Method for Flash and Fire Points by ClevelandOpen Cup TesterD140 Practice for Sampling Bituminous MaterialsD1310 Test Method for Flash Point and Fire Point of Liquidsby Tag Open-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 PerformanceD6300 Practice for Determination of Precision and BiasData for Use in Test Methods for Petroleum Products andLubricantsE1 Specification for ASTM Liquid-in-Glass ThermometersE77 Test Method for Inspection and Verification of Ther-mometersE300 Practice for Sampling Industrial ChemicalsE644 Test Methods for Testing Industrial Resistance Ther-mometersE1137/E1137M Specification for Industrial Platinum Resis-tance Thermometers2.2 IP Standard:IP36 Test for Flash and Fire Points by Cleveland Open Cup31This test method is under the jurisdiction of ASTM Committee D04 on Roadand Paving Materials and is the direct responsibility of Subcommittee D04.47 onMiscellaneous Asphalt Tests.Current edition approved Dec.1,2013.Published January 2014.Originallyapproved in 1962.Last previous edition approved in 2008 as D3143 08.DOI:10.1520/D3143_D3143M-13.2For 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 Energy Institute,61 New Cavendish St.,London,WIG 7AR,U.K.,http:/www.energyinst.org.uk.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.Summary of Test Method3.1 The sample is placed in the cup of the tester and heatedat a slow but constant rate.A small test flame is passed at auniform rate in a level plane across the cup at specifiedintervals.The flash point is the lowest temperature at whichapplication of the test flame causes the vapor at the surface ofthe liquid to flash.4.Significance and Use4.1 This test method is useful in determining that an asphaltcutback has been prepared with solvents that meet the desiredrange of flammability,and
