Designation:D665141Designation:135/06Standard Test Method forRust-Preventing Characteristics of Inhibited Mineral Oil inthe Presence of Water1This standard is issued under the fixed designation D665;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.1NOTESubsection 7.3 was corrected editorially in February 2015.1.Scope*1.1 This test method covers the evaluation of the ability ofinhibited mineral oils,particularly steam-turbine oils,to aid inpreventing the rusting of ferrous parts should water becomemixed with the oil.This test method is also used for testingother oils,such as hydraulic oils and circulating oils.Provisionis made in the procedure for testing heavier-than-water fluids.NOTE1For synthetic fluids,such as phosphate ester types,the plasticholder and beaker cover should be made of chemically resistant materialsuitable for the type of fluid tested.1.2 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.3 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.For specificwarning statements,see 7.4 7.6.2.Referenced Documents2.1 ASTM Standards:2A108 Specification for Steel Bar,Carbon and Alloy,Cold-FinishedA240/A240M Specification for Chromium and Chromium-Nickel Stainless Steel Plate,Sheet,and Strip for PressureVessels and for General ApplicationsD91 Test Method for Precipitation Number of LubricatingOilsD1193 Specification for Reagent WaterD2422 Classification of Industrial Fluid Lubricants by Vis-cosity SystemD3603 Test Method for Rust-Preventing Characteristics ofSteam Turbine Oil in the Presence of Water(HorizontalDisk Method)D4057 Practice for Manual Sampling of Petroleum andPetroleum ProductsE1 Specification for ASTM Liquid-in-Glass Thermometers2.2 Other Documents:Motor Fuels,Section I,Annex A2,Table 32,ReferenceMaterials and Blending Accessories3Specifications-IP Standard Thermometers,Vol 2,AppendixA4Specifications for IP Standard Reference Liquids,AppendixB4SAE Standard J405 Chemical Composition of SAE WroughtStainless Steels5BS 871 Specification for abrasive papers and cloths4BS 970Part 1:Carbon and Carbon Manganese SteelsIncluding Free Cutting Steels43.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 rust,na special case of corrosion that can be visuallyobserved on the surface of round steel test rods as reddish-brown discoloration or small black spots.1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.C0.02 on Corrosion and Water/Air Separability.Current edition approved Oct.1,2014.Published November 2014.Originallyapproved in 1942.Last previous edition approved in 2012 as D665 12.DOI:10.1520/D0665-14E01.This standard has been developed through the cooperative effort between ASTMInternational and the Energy Institute,London.The EI and ASTM Internationallogos imply that the ASTM International and EI standards are technicallyequivalent,but does not imply that both standards are editorially identical.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.3See 1996 Annual Book of ASTM Standards,Vol 05.04.4Annual Book of IP Standard Methods for Analysis and Testing of Petroleum andRelated Products,Vol 2.Available from Energy Institute,61 New Cavendish St.,London,WIG 7AR,U.K.51995 SAE Handbook,Vol 1.Available from Society of Automotive Engineers(SAE),400 Commonwealth Dr.,Warrendale,PA 15096-0001.*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 4.Summary of Test Method4.1 A mixture of 300 mL of the oil under test is stirred with30 mL of distilled water or synthetic sea water,as required,ata temperature of 60 C 6 1 C with a cylindrical steel test rodcompletely immersed therein.It is recommended to run the testfor 4 h;however,the test period may,at the discretion of thecontracting parties,be for a shorter or longer period.The testrod is observed for signs of rusting and,if desired,degree ofrusting.NOTE2Until 1999 it was customary to run the test for 24 h.A roundrobin with comparisons of different test times showed that no statisticallysignificant differences in
