Designation:D682308(Reapproved 2021)Standard Specification forCommercial Boiler Fuels With Used Lubricating Oils1This standard is issued under the fixed designation D6823;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.Scope1.1 This specification covers four grades of fuel oil made ofat least 25%used lubricating oils.The four grades of fuel areintended for use in various types of fuel-oil-burning industrialequipment and commercial boilers under various climatic andoperating conditions.These fuels are not intended for use inresidential heaters.1.1.1 Grades RFC4,RFC5L,RFC5H and RFC6 are usedlubricating oil blends of increasing viscosity,with or withoutmiddle distillate or residual fuel oil,or both,that are intendedfor use in industrial burners and commercial boilers equippedto handle these types of fuels.This specification is forapplications where Specification D6448 would not meet theperformance or other requirements of the burner or boiler inquestion.NOTE1For information on the significance of the terminology andtest methods used in this specification,see Appendix X1.1.2 This specification is for use in contracts for the purchaseof fuel oils derived from used lubricating oil and for theguidance of consumers of such fuels.This specification doesnot address the frequency with which any particular test mustbe run.1.3 Nothing in this specification shall preclude observanceof national or local regulations which can be more restrictive.In some jurisdictions,used oil is considered a hazardous wasteand fuels derived from used oil are required to meet certaincriteria before use as a fuel.NOTE2For United States federal requirements imposed on used oilgenerators,transporters and transfer facilities,reprocessors,marketers,and burners,see 40 CFR Part 279.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 D4865.1.4 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.4.1 ExceptionTable 1 and Table X1.1 include inch-pound values in parentheses for information only.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 TesterD93 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)D240 Test Method for Heat of Combustion of Liquid Hy-drocarbon Fuels by Bomb CalorimeterD396 Specification for Fuel OilsD445 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 ProductsD664 Test Method for Acid Number of Petroleum Productsby Potentiometric TitrationD974 Test Method for Acid and Base Number by Color-Indicator TitrationD1266 Test Method for Sulfur in Petroleum Products(LampMethod)D1298 Test Method for Density,Relative Density,or APIGravity of Crude Petroleum and Liquid Petroleum Prod-ucts by Hydrometer Method1This specification is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.P0 on Recycled Products.Current edition approved Nov.1,2021.Published November 2021.Originallyapproved in 2002.Last previous edition approved in 2013 as D6823 08(2013).DOI:10.1520/D6823-08R21.2For 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.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.1D1552 Test Method for Sulfur in Petroleum Produc
