Designation:D682413(Reapproved 2018)An American National StandardStandard Test Method forDetermining Filterability of Aviation Turbine Fuel1This standard is issued under the fixed designation D6824;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 a procedure for determining thefilterability of aviation turbine fuels(for other middle distillatefuels,see Test Method D6426).NOTE1ASTM specification fuels falling within the scope of this testmethod are Specifications D1655 and D6615 and the military fuelscovered in the military specifications listed in 2.2.1.2 This test method is not applicable to fuels that containundissolved water.1.3 The values stated in SI units are to be regarded asstandard.The values given in parentheses after SI units areprovided for information only and are not considered standard.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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.5 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:2D1655 Specification for Aviation Turbine FuelsD4057 Practice for Manual Sampling of Petroleum andPetroleum ProductsD4176 Test Method for Free Water and Particulate Contami-nation in Distillate Fuels(Visual Inspection Procedures)D4177 Practice for Automatic Sampling of Petroleum andPetroleum ProductsD4860 Test Method for Free Water and Particulate Contami-nation in Middle Distillate Fuels(Clear and Bright Nu-merical Rating)D5452 Test Method for Particulate Contamination in Avia-tion Fuels by Laboratory FiltrationD6300 Practice for Determination of Precision and BiasData for Use in Test Methods for Petroleum Products andLubricantsD6426 Test Method for Determining Filterability of MiddleDistillate Fuel OilsD6615 Specification for Jet B Wide-Cut Aviation TurbineFuel2.2 Military Standards:3MIL-DTL-5624 Turbine Fuel,Aviation,Grades JP-4,JP-5,and JP-5/JP-8 STMIL-DTL-25524 Turbine Fuel,Aviation,Thermally StableMIL-DTL-38219 Turbine Fuels,Low Volatility,JP-7MIL-DTL-83133 Turbine Fuels,Aviation,Kerosine Types,NATO F-34(JP-8),NATO F-35,and JP-8+1003.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 filterability,na measure of the rapidity with which astandard filter medium is plugged by insoluble matter in fueland may be described as a function of pressure or volume:3.1.1.1 filterability(by pressure),nthe pressure dropacross a filter medium when 300 mL of fuel is passed at a rateof 20 mL min.3.1.1.2 filterability(by volume),nthe volume of fuelpassed when a pressure of 104 kPa(15 psig)is reached.3.1.1.3 DiscussionFilterability by volume is used whenless than 300 mL passes the filter at a pressure up to 104 kPa(15 psig).3.1.1.4 filterability quality factor(F-QF),na value thatdefines the filter plugging tendency of a fuel caused byparticulates.3.1.1.5 DiscussionThe F-QF value is calculated using thevolume and pressure attained at the end of the test cycle,1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.J0.01 on Jet Fuel Specifications.Current edition approved Oct.1,2018.Published November 2018.Originallyapproved in 2002.Last previous edition approved in 2013 as D6824 131.DOI:10.1520/D6824-13R18.2For 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 Standardization Documents Order Desk,DODSSP,Bldg.4,Section D,700 Robbins Ave.,Philadelphia,PA 19111-5098.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 according to one of two equations,depending on the outcomeof the test.(See Section 10,Calculations.)4.Summary of Test Method4.1 A sample is passed at a constant rate(20 mL min)through a standard porosity filter medium
