Designation:D360314Standard Test Method forRust-Preventing Characteristics of Steam Turbine Oil in thePresence of Water(Horizontal Disk Method)1This standard is issued under the fixed designation D3603;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 the ability of steam-turbine oilsto prevent the rusting of horizontal and vertical ferrous surfaceswhen water becomes mixed with the oil.1.2 The values stated in SI units are to be regarded asstandard.The values given in parentheses are for informationonly.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.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 WaterE1 Specification for ASTM Liquid-in-Glass ThermometersE2251 Specification for Liquid-in-Glass ASTM Thermom-eters with Low-Hazard Precision Liquids2.2 Other Standards:IP 60/80 Specification for Petroleum Spirit3SAE 30304 Steel,Corrosion-Resistant,Sheet,Strip,andPlate,19Cr-9.2Ni4BS 970:Part 1:1983 Specification for wrought steels formechanical and allied engineering purposes.General in-spection and testing procedures and specific requirementsfor carbon,carbon manganese,alloy and stainless steels5BS 871:1981 Specification for abrasive papers and cloths3.Summary of Test Method3.1 The test method involves completely immersing a hori-zontal steel disk and vertical steel cylinder in a stirred mixtureof 275 mL of the oil under test and 25 mL of distilled water(water conforming to Specification D1193,Type II)at atemperature at 60 C(140 F).3.2 The horizontal specimen allows water to puddle on thesurface,and the vertical specimen is continually washed withthe oil-water mixture during the test.3.3 The test is run for 6 h and the specimens are evaluated.4.Significance and Use4.1 Horizontal metal surfaces,on which water droplets tendto be retained,are more prone to rusting and corrosion thanvertical or sloping surfaces.This test method is therefore morediscriminating than Test Method D665(Procedure A),since itgives a separate evaluation of the oil on a horizontal and avertical surface.The test method indicates the ability of oils toprevent rusting and corrosion of all ferrous surfaces in steamturbines under full flow and quasi-static conditions.It is usedfor specification of new oils.5.Apparatus5.1 Oil BathA thermostatically controlled liquid bathcapable of maintaining a temperature in the oil sample of 60 C6 1 C(140 F 6 2 F).The bath shall have a cover with holesto accommodate the test beakers.NOTE1The bath used for Test Method D665 may be used with slightmodification,that is,the centers of the beaker holes are moved from1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricantsand is the direct responsibility ofD02.C0.02 on Corrosion and Water/Air Separability.Current edition approved Dec.1,2014.Published February 2015.Originallyapproved in 1977.Last previous edition approved in 2007 as D3603 07.DOI:10.1520/D3603-14.2For 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.uk.4Available from SAE World Headquarters,400 Commonwealth Drive,Warrendale,PA 15096-0001.5BSI,British Standards,389 Chiswick High Road,London W4 4AL,UnitedKingdom.*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 6.4 mm to 18.3 mm(14in.to2332in.)from the axes of the stirrers.NOTE2To indicate the temperature,a thermometer conforming to therequirements of ASTM Thermometer 9C or 9F,or IP Thermometer 21C,as prescribed in Specification E1 should be used.Thermometric devicessuch as RTDs,themistors,thermocouples,or a thermometer conforming toSpecification E2251 may be used.NOTE3Thermometer S130C(S130F)in Specification E2251 may besuitable.Temperature range:7 C to 105 C and scale error,max.:0.5 Cas compared to Thermometer 9
