Designation:D816622Standard Test Method forSizing and Counting Particulates in Middle Distillate Fuelsand Biodiesel Blend(B6 to B20)Using Continuous Flow andBottle Sampler Particle Contamination Monitors1This standard is issued under the fixed designation D8166;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 uses specific particle contaminationmonitors(PCMs)to count and measure the size of disperseddirt particles,water droplets and other particulates,in middledistillate fuel,in the overall range from 4 m to 70 m and inthe size bands 4 m,6 m,14 m,and 30 m.NOTE1The term particle contamination monitor,as used in this testmethod,is the same as that defined in ISO 21018-4;an instrument thatautomatically measures the concentrations of particles suspended in a fluidat certain sizes and cannot be calibrated in accordance with ISO 11171whose output may be as a particle size distribution at limited sizes or asa contamination code.1.2 This test method has interim repeatability precisiononly,see Section 14 for more information.NOTE2ASTM specification fuels falling within the scope of this testmethod include Specifications:D975,D1655,D3699,D7467,MIL-DTL-83133,MIL-DTL-5624,and distillate grades of D396 and D2880.NOTE3For the purposes of this test method,water droplets arecounted as particles,and agglomerated particles are detected and countedas a single larger particle.Dirt includes microbial particulates.Althoughthe projected area of a particle is measured,this is expressed as thediameter of a circle for the purposes of this test method.The detector isunable to distinguish between dirt and water particles.NOTE4This test method may be used for particle sizes bands up to70 m,however the interim repeatability has only been determined for thesize bands 4 m,6 m,and 14 m.All measurements are counts permillilitre.1.3 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.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:2D396 Specification for Fuel OilsD975 Specification for Diesel FuelD1655 Specification for Aviation Turbine FuelsD2880 Specification for Gas Turbine Fuel OilsD3699 Specification for KerosineD4057 Practice for Manual Sampling of Petroleum andPetroleum ProductsD4175 Terminology Relating to Petroleum Products,LiquidFuels,and LubricantsD4177 Practice for Automatic Sampling of Petroleum andPetroleum ProductsD4306 Practice for Aviation Fuel Sample Containers forTests Affected by Trace ContaminationD5854 Practice for Mixing and Handling of Liquid Samplesof Petroleum and Petroleum ProductsD6300 Practice for Determination of Precision and BiasData for Use in Test Methods for Petroleum Products,Liquid Fuels,and LubricantsD7467 Specification for Diesel Fuel Oil,Biodiesel Blend(B6 to B20)D7619 Test Method for Sizing and Counting Particles inLight and Middle Distillate Fuels,by Automatic ParticleCounter2.2 U.S.Dept.of Defense Specifications:3MIL-DTL-5624 Specification:Turbine Fuel,Aviation,Grades JP-4(NATO F-40 and JP-5(NATO F-44)1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.14 on Stability,Cleanliness and Compatibility of Liquid Fuels.Current edition approved Oct.1,2022.Published October 2022.Originallyapproved in 2017.Last previous edition approved in 2021 as D8166 21a.DOI:10.1520/D8166-22.2For 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 online at ASSIST Quick Search(http:/quicksearch.dla.mil).*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 Recommen
