Designation:D596715aStandard Test Method forEvaluation of Diesel Engine Oils in T-8 Diesel Engine1This standard is issued under the fixed designation D5967;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 covers an engine test procedure forevaluating diesel engine oils for performance characteristics,including viscosity increase and soot concentrations(loading).2This test method is commonly referred to as the Mack T-8.1.2 This test method also provides the procedure for runningan extended length T-8 test,which is commonly referred to asthe T-8E and an abbreviated length test,which is commonlyreferred to as T-8A.The procedures for the T-8E and the T-8Aare identical to the T-8 with the exception of the itemsspecifically listed in Annex A8 and Annex A9 respectively.Additionally,the procedure modifications listed in Annex A8and Annex A9 refer to the corresponding section of the T-8procedure.1.3 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.3.1 ExceptionsWhere there is no direct SI equivalentsuch as the units for screw threads,National Pipe Threads/diameters,tubing size,sole source equipment suppliers,and oilconsumption in grams per kilowatt-hour.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.See Annex A6 forspecific safety precautions.1.5 A Table of Contents follows:Scope1Referenced Documents2Terminology3Summary of Test Method4Significance and Use5Apparatus6General Description6.1The Test Engine6.2Mack Test Engine6.2.1Engine Cooling System6.2.2Engine Oil System6.2.3Auxiliary Oil System6.2.4Crankcase Aspiration6.2.5Blowby Meter6.2.6Air Supply and Filtration6.2.7Fuel Supply6.2.8Intake Manifold Temperature Control6.2.9Engine Fluids7Test Oil7.1Test Fuel7.2Engine Coolant7.3Cleaning Materials7.4Preparation of Apparatus at Rebuild8Cleaning of Parts8.1Valves,Seats,Guides,and Springs8.2Cylinder Liner,Piston,and Piston Ring Assembly8.3Injectors and Injection Pump8.4Assembly Instructions8.5Measurements8.6Laboratory and Engine Test Stand Calibration/Non-ReferenceRequirements9Calibration Frequency9.1Calibration Reference Oils9.2Test Numbering9.3New Laboratories and New Test Stands9.4Calibrated Laboratories and Test Stands9.5Calibration Test Acceptance9.6Failing Calibration Tests9.7Non-Reference Oil Test Requirements9.8Procedure10Pretest Procedure10.1Engine Start-Up10.2Engine Shutdown10.3Test Cycle10.4Oil Addition/Drain10.5Oil Samples10.6Oil Consumption Calculations10.7Fuel Samples10.8Periodic Measurements10.9Blowby10.10Centrifugal Oil Filter Mass Gain10.11Oil Filter P Calculation10.12Post Test10.13Inspection of Fuel and Oil During Test11Oil Inspection11.1Fuel Inspections11.2Oil Consumption11.3Report12Reporting Test Results12.1Deviations from Test Operational Limits12.2Electronic Transmission of Test Results12.3Plots of Operational Data12.41This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.B0.02 on Heavy Duty Engine Oils.Current edition approved Oct.1,2015.Published October 2015.Originallyapproved in 1996.Last previous edition approved in 2015 as D5967 15.DOI:10.1520/D5967-15A.2The ASTM Test Monitoring Center will update changes in this test method bymeans of Information Letters.This edition incorporates revisions contained in allinformation letters through 151.Information letters may be obtained from theASTM Test Monitoring Center,6555 Penn Avenue,Pittsburgh,PA 15206-4489,Attention:Administrator.*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 States1 Precision and Bias13Precision13.1Bias13.2Keywords14AnnexesReport FormsAnnex A1Sensor LocationsAnnex A2Kinematic Viscosity At 100C For Test Method D5967 SamplesAnnex A3Enhanced Thermal Gravimetric Analysis(TGA)ProcedureAnnex A4Procurement of Test MaterialsAnnex A5Safety PrecautionsAnnex A6Data DictionaryAnnex A7T-8E Extended Length Test RequirementsAnnex A8T-8A Abbreviated Length Test RequirementsAnnex A92.Referenced Documents2.1 ASTM Standards:3D86 Test Method for Distillation of Petroleum Products atAtmospheric PressureD93 Test Methods for Flash Point by Pensky-MartensClosed Cup TesterD97 Test Method for Pour Point of Petroleum ProductsD130 Test Method for Corrosiveness to Copper from Petro-leum Products by Copper Strip TestD235 Specification for Mineral Spirits(Petroleum Spi
