Designation:D681302a(Reapproved 2013)Standard Guide forPerformance Evaluation of Hydraulic Fluids for PistonPumps1This standard is issued under the fixed designation D6813;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.Scope1.1 This guide covers the establishment of test protocols andmethodologies for determining the suitability of fluids for usein fluid power systems that incorporate axial or radial pistonpumps.The suitability of all fluid types to meet specific levelsof performance in piston pumps is addressed.These fluidsinclude,but are not limited to formulations based on mineral,synthetic or vegetable oil base stocks.The finished fluids maybe in the form of straight oils,soluble oils or invert emulsions.1.2 The test protocols and methodologies described in thisguide have been selected for their ability to distinguishbetween highly acceptable,acceptable and unacceptable fluidperformance in piston pumps.They take into account the broadrange of operating conditions piston pumps are subjected to,aswell as the common variations in design and materials ofconstruction among pump manufacturers.1.3 This guide is intended to complement proprietary testprotocols and methodologies employed by some piston pumpmanufacturers.The test protocols and methodologies withinthis guide may help pump manufacturers,fluid formulators andend users accurately screen potential fluids for specific perfor-mance characteristics.The results of this screening may besufficient in certain instances for pump manufacturers to foregorequirements for additional fluid performance tests.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 requirements prior to use.2.Referenced Documents2.1 ASTM Standards:2D92 Test Method for Flash and Fire Points by ClevelandOpen Cup TesterD93 Test Methods for Flash Point by Pensky-MartensClosed Cup TesterD95 Test Method for Water in Petroleum Products andBituminous Materials by DistillationD97 Test Method for Pour Point of Petroleum ProductsD130 Test Method for Corrosiveness to Copper from Petro-leum Products by Copper Strip TestD445 Test Method for Kinematic Viscosity of Transparentand Opaque Liquids(and Calculation of Dynamic Viscos-ity)D482 Test Method for Ash from Petroleum ProductsD611 Test Methods for Aniline Point and Mixed AnilinePoint of Petroleum Products and Hydrocarbon SolventsD664 Test Method for Acid Number of Petroleum Productsby Potentiometric TitrationD665 Test Method for Rust-Preventing Characteristics ofInhibited Mineral Oil in the Presence of WaterD874 Test Method for Sulfated Ash from Lubricating Oilsand AdditivesD877 Test Method for Dielectric Breakdown Voltage ofInsulating Liquids Using Disk ElectrodesD892 Test Method for Foaming Characteristics of Lubricat-ing OilsD943 Test Method for Oxidation Characteristics of InhibitedMineral OilsD974 Test Method for Acid and Base Number by Color-Indicator TitrationD1121 Test Method for Reserve Alkalinity of Engine Cool-ants and AntirustsD1123 Test Methods for Water in Engine Coolant Concen-trate by the Karl Fischer Reagent MethodD1169 Test Method for Specific Resistance(Resistivity)ofElectrical Insulating LiquidsD1298 Test Method for Density,Relative Density,or APIGravity of Crude Petroleum and Liquid Petroleum Prod-ucts by Hydrometer MethodD1401 Test Method for Water Separability of Petroleum Oilsand Synthetic FluidsD1500 Test Method for ASTM Color of Petroleum Products(ASTM Color Scale)1This guide is under the jurisdiction of ASTM Committee D02 on PetroleumProducts,Liquid Fuels,and Lubricants and is the direct responsibility of Subcom-mittee D02.N0.07 on Lubricating Properties.Current edition approved May 1,2013.Published August 2013.Originallyapproved in 2002.Last previous edition approved in 2007 as D6813 02a(2007).DOI:10.1520/D6813-02AR13.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 D1533 Test Method for Water in Insulating Liquids byCoulometric Karl Fischer TitrationD2070 Test Method for Thermal Stability of Hydraulic OilsD2270 Practice for Calculating Viscosity Index from Kine-matic Viscosity at 40 and 100CD2272 Test Method for Oxidation Stability of Steam Tur-bine Oils by Rotating Pressure VesselD2273 Test Method for Trace Sediment in Lubricating OilsD2422 Classification of Industrial Fluid Lubricants b
