Designation:D580021Standard Test Method forEvaporation Loss of Lubricating Oils by the Noack Method1This standard is issued under the fixed designation D5800;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 four procedures for determiningthe evaporation loss of lubricating oils(particularly engineoils).The evaporation measured is reported as percent totalloss.The test method relates to one set of operating conditionsbut may be readily adapted to other conditions as required.1.2 Procedure B and Procedure D that are in the mainsection of the test method provide equivalent results.Proce-dures A and C,which are in Annex A1 and Annex A2,haveequivalent results.It has been determined that Procedures Aand C show a slight bias when compared to Procedures B andD.Procedures B and D give slightly higher results versusProcedures A and C on formulated engine oils,while Proce-dures B and D give lower results versus ProceduresAand C onbasestocks.Thus,a correction factor is utilized to convertbetween the two sets of Procedures based on the fluid type.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:2D4057 Practice for Manual Sampling of Petroleum andPetroleum ProductsD4177 Practice for Automatic Sampling of Petroleum andPetroleum ProductsD6299 Practice for Applying Statistical Quality Assuranceand Control Charting Techniques to Evaluate AnalyticalMeasurement System PerformanceD6300 Practice for Determination of Precision and BiasData for Use in Test Methods for Petroleum Products,Liquid Fuels,and Lubricants2.2 DIN Standards:3DIN 1725 Specification for Aluminum AlloysDIN 12785 Specifications for Glass Thermometers3.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 evaporation loss,nof a lubricating oil by the Noackmethod,that mass of volatile oil vapors lost when the oil isheated in a test crucible through which a constant flow of air isdrawn.3.1.2 volatility,nthe tendency of a liquid to form a vapor.4.Summary of Test Method4.1 A measured quantity of sample is placed in an evapo-ration crucible or reaction flask that is then heated to 250 Cwith a constant flow of air drawn through it for 60 min.Theloss in mass of the oil is determined.4.2 Interlaboratory tests have shown that Procedure A,Procedure B,Procedure C,and Procedure D yield statisticallyequivalent precision,with a correlation coefficient of R2=0.996(see research report).5.Significance and Use5.1 The evaporation loss is of particular importance inengine lubrication.Where high temperatures occur,portions ofan oil can evaporate.5.2 Evaporation may contribute to oil consumption in anengine and can lead to a change in the properties of an oil.1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.06 on Analysis of Liquid Fuels and Lubricants.Current edition approved Oct.1,2021.Published October 2021.Originallyapproved in 1995.Last previous edition approved in 2020 as D5800 20.DOI:10.1520/D5800-21.2For 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.3Available from Deutsches Institut fr Normung e.V.(DIN),Am DIN-Platz,Burggrafenstrasse 6,10787 Berlin,Germany,http:/www.din.de.*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.15.3 Many engine manufacturers specify a maximum allow-able evaporation loss.5.4 Some engine manufacturers,when specifying a m
