Designation:D39621Standard Specification forFuel Oils1This standard is issued under the fixed designation D396;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.1.Scope*1.1 This specification(see Note 1)covers grades of fuel oilintended for use in various types of fuel-oil-burning equipmentunder various climatic and operating conditions.These gradesare described as follows:1.1.1 Grades No.1 S5000,No.1 S500,No.1 S15,No.2S5000,No.2 S500,and No.2 S15 are middle distillate fuelsfor use in domestic and small industrial burners.Grades No.1S5000,No.1 S500,and No.1 S15 are particularly adapted tovaporizing type burners or where storage conditions requirelow pour point fuel.1.1.2 Grades B6B20 S5000,B6B20 S500,and B6B20S15 are middle distillate fuel/biodiesel blends for use indomestic and small industrial burners.1.1.3 Grades No.4(Light)and No.4 are heavy distillatefuels or middle distillate/residual fuel blends used incommercial/industrial burners equipped for this viscosityrange.1.1.4 Grades No.5(Light),No.5(Heavy),and No.6 areresidual fuels of increasing viscosity and boiling range,used inindustrial burners.Preheating is usually required for handlingand proper atomization.NOTE1For information on the significance of the terminology andtest methods used in this specification,see Appendix X1.NOTE2A more detailed description of the grades of fuel oils is givenin X1.3.1.2 This specification is for the use of purchasing agenciesin formulating specifications to be included in contracts forpurchases of fuel oils and for the guidance of consumers of fueloils in the selection of the grades most suitable for their needs.1.3 Nothing in this specification shall preclude observanceof federal,state,or local regulations which can be morerestrictive.1.4 The values stated in SI units are to be regarded asstandard.1.4.1 Non-SI units are provided in Table 1 and Table 2 andin 7.1.2.1/7.1.2.2 because these are common units used in theindustry.NOTE3The generation and dissipation of static electricity can createproblems in the handling of distillate burner fuel oils.For more informa-tion on the subject,see Guide D4865.1.5 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:2D56 Test Method for Flash Point by Tag Closed Cup TesterD86 Test Method for Distillation of Petroleum Products andLiquid Fuels at Atmospheric PressureD93 Test Methods for Flash Point by Pensky-MartensClosed Cup TesterD95 Test Method for Water in Petroleum Products andBituminous Materials by DistillationD97 Test Method for Pour Point of Petroleum ProductsD129 Test Method for Sulfur in Petroleum Products(Gen-eral High Pressure Decomposition Device Method)D130 Test Method for Corrosiveness to Copper from Petro-leum Products by Copper Strip TestD445 Test Method for Kinematic Viscosity of Transparentand Opaque Liquids(and Calculation of Dynamic Viscos-ity)D473 Test Method for Sediment in Crude Oils and Fuel Oilsby the Extraction MethodD482 Test Method for Ash from Petroleum ProductsD524 Test Method for Ramsbottom Carbon Residue ofPetroleum ProductsD664 Test Method for Acid Number of Petroleum Productsby Potentiometric TitrationD975 Specification for Diesel Fuel1This specification is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.E0 on Burner,Diesel and Non-Aviation Gas Turbine Fuels.Current edition approved April 1,2021.Published April 2021.Originallyapproved in 1934.Last previous edition approved in 2020 as D396 20.DOI:10.1520/D0396-21.2For 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.*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.1D1266 Test Method for Sulfur in Petroleum Products(LampMethod)D1298 Test Method for Density,Relative Density,or
