Designation:D622409Standard Practice forIn-Service Monitoring of Lubricating Oil for Auxiliary PowerPlant Equipment1This standard is issued under the fixed designation D6224;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.INTRODUCTIONA more systematic approach to monitoring auxiliary power plant equipment can help to minimizethe high cost of oil changes and unplanned shutdowns.These avoided costs must be balanced againstthe cost of sampling and laboratory testing.This practice is designed to help the user plan and implement a meaningful,cost-effective programof sampling and testing of oils in use.Also covered are some important aspects of interpretation ofresults and suggested action steps so as to maximize service life of the oil and equipment.This practice is designed to help the user evaluate the condition of the lubricant through its life cycleby carrying out a meaningful program of sampling and testing of oils in use.This practice is performedin order to collect data and monitor trends which suggest any signs of lubricant deterioration and toensure a safe,reliable and cost-effective operation of the monitored plant equipment.1.Scope1.1 This practice covers the requirements for the effectivemonitoring of mineral oil and phosphate ester fluid lubricatingoils in service auxiliary(non-turbine)equipment used forpower generation.Auxiliary equipment covered includes gears,hydraulic systems,diesel engines,pumps,compressors,andelectrohydraulic control(EHC)systems.It includes samplingand testing schedules and recommended action steps,as well asinformation on how oils degrade.NOTE1Other types of synthetic lubricants are sometimes used but arenot addressed in this practice because they represent only a small fractionof the fluids in use.Users of these fluids should consult the manufacturerto determine recommended monitoring practices.1.2 This practice does not cover the monitoring of lubricat-ing oil for steam and gas turbines.Rather,it is intended tocomplement Practice D4378.1.3 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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D92 Test Method for Flash and Fire Points by ClevelandOpen Cup TesterD95 Test Method for Water in Petroleum Products andBituminous Materials by DistillationD96 Test Method for Water and Sediment in Crude Oil byCentrifuge Method(Field Procedure)(Withdrawn 2000)3D257 Test Methods for DC Resistance or Conductance ofInsulating MaterialsD445 Test Method for Kinematic Viscosity of Transparentand Opaque Liquids(and Calculation of Dynamic Viscos-ity)D664 Test Method for Acid Number of Petroleum Productsby Potentiometric TitrationD665 Test Method for Rust-Preventing Characteristics ofInhibited Mineral Oil in the Presence of WaterD892 Test Method for Foaming Characteristics of Lubricat-ing OilsD893 Test Method for Insolubles in Used Lubricating Oils1This practice is under the jurisdiction of ASTM Committee D02 on PetroleumProducts and Lubricantsand is the direct responsibility of Subcommittee D02.C0.01on Turbine Oil Monitoring,Problems and Systems.Current edition approved July 1,2009.Published November 2009.Originallyapproved in 1998.Last previous edition approved in 2002 as D622402.DOI:10.1520/D6224-09.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 D943 Test Method for Oxidation Characteristics of InhibitedMineral OilsD974 Test Method for Acid and Base Number by Color-Indicator TitrationD1169 Test Method for Specific Resistance(Resistivity)ofElectrical Insulating LiquidsD1298 Test Method for Density,Relative Density(SpecificGravity),or API Gravity of Crude Petroleum and LiquidPetroleum Products by Hydrometer MethodD1401 Test Method for Water Separability of Petroleum Oilsand Synthetic FluidsD1500 Test Method for ASTM Color of Petroleum Products(ASTM Color Scale)D1533 Test Method for Water in Insulating Liquids byCoulometric Karl Fischer TitrationD1744 Test Method for Determination of Water in LiquidPetroleum Products by Karl Fischer Reagent(Withdrawn2000)3D2272 Test Method for Oxidation Stability of
