Designation:D553494(Reapproved 2011)1Standard Test Method forVapor-Phase Rust-Preventing Characteristics of HydraulicFluids1This standard is issued under the fixed designation D5534;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.1NOTEUpdated Note 2 and added mercury caveat editorially in August 2011.1.Scope1.1 This test method covers the ability of hydraulic fluids toprevent the rusting of steel in the vapor phase over thehydraulic fluid and water.1.2 The values stated in SI units are to be regarded asstandard.The values given in parentheses are for informationonly.1.3 WARNINGMercury has been designated by manyregulatory agencies as a hazardous material that can causecentral nervous system,kidney and liver damage.Mercury,orits vapor,may be hazardous to health and corrosive tomaterials.Caution should be taken when handling mercury andmercury containing products.See the applicable product Ma-terial Safety Data Sheet(MSDS)for details and EPAswebsitehttp:/www.epa.gov/mercury/faq.htmfor addi-tional information.Users should be aware that selling mercuryand/or mercury containing products into your state or countrymay be prohibited by law.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.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 LubricatingOilsD665 Test Method for Rust-Preventing Characteristics ofInhibited Mineral Oil in the Presence of WaterD1193 Specification for Reagent WaterD3603 Test Method for Rust-Preventing Characteristics ofSteam Turbine Oil in the Presence of Water(HorizontalDisk Method)E1 Specification for ASTM Liquid-in-Glass Thermometers2.2 Other Standards:IP 60/80 Specification for Petroleum Spirit3BS 970:1955EN3B Specification for wrought steels43.Summary of Test Method3.1 This test method is divided into two parts:3.1.1 Part AUsed only for fluids where water is thecontinuous phase.Examples of such fluids include water-glycol hydraulic fluids and high-water-content hydraulic fluids.Do not use Part A to evaluate invert emulsion hydraulic fluids.3.1.2 Part BUsed for both water-containing fluids andcompletely water-free fluids such as petroleum based hydraulicfluids,except phosphate esters.In Part B a small beaker ofwater is present to provide water vapor to cause corrosion inthe absence of a vapor-phase inhibitor in the fluid.Part B is theappropriate procedure for evaluating invert emulsion hydraulicfluids.3.2 In both Part A and Part B,a steel specimen is attachedto the underside of the cover of a beaker containing the fluidunder test.The apparatus and specimen are identical to those ofTest Method D3603.The fluid is brought to a test temperatureof 60C(140F).3.3 In Part B,the test specimen is exposed to the vapor fromthe fluid for 30 min prior to the introduction of water.A beakerof water is then placed in the undercarriage of the cover.1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.N0.02 on Industrial Applications.Current edition approved July 1,2011.Published August 2011.Originallyapproved in 1994.Last previous edition approved in 2005 as D553494(2005).DOI:10.1520/D5534-94R11E01.2For 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 Energy Institute,61 New Cavendish St.,London,WIG 7AR,U.K.,http:/www.energyinst.org.4Available from IHS,15 Inverness Way East,Englewood,CO 80112,http:/.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.4 After 6 h,the apparatus is disassembled and the speci-men is rated visually for the presence of rust.3.5 Since the apparatus and test conditions are identical,Part A can be completed simultaneously with Test MethodD3603 by adding the vapor-phase specimen to that procedure.4.Significance and Use4.1 Procedures such as Test Methods D665 and D3603assess the ability of new or unused hydraulic fluid to preventrusting on wetted steel surfaces but do not address theprevention of rusting in the vapor space above the fluid.Thisprocedure addresses the latter question under one set of testconditions
