Designation:D11710Standard Guide forSampling,Test Methods,and Specifications for ElectricalInsulating Oils of Petroleum Origin1This standard is issued under the fixed designation D117;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 describes methods of testing and specifica-tions for electrical insulating oils of petroleum origin intendedfor use in electrical cables,transformers,oil circuit breakers,and other electrical apparatus where the oils are used asinsulating,or heat transfer media,or both.1.2 The purpose of this guide is to outline the applicabilityof the available test methods.Where more than one is availablefor measuring a given property,their relative advantages aredescribed,along with an indication of laboratory convenience,precision,(95%confidence limits),and applicability to spe-cific types of electrical insulating oils.1.3 This guide is classified into the following categories:Sampling Practices,Physical Tests,Electrical Tests,ChemicalTests,and Specifications.Within each test category,the testmethods are listed alphabetically by property measured.A listof standards follows:CategorySectionASTM MethodSampling:3D923,D2759,D3305Physical Tests:Aniline Point4D611Coefficient of Thermal Ex-pansion5D1903Color6D1500Examination:Visual Infrared7D1524,D2144Flash and Fire Point8D92Interfacial Tension9D971,D2285Pour Point of PetroleumProducts10D97Particle Count in MineralInsulating Oil11D6786Refractive Index12D1218,D1807Relative Density(SpecificGravity)13D287,D1217,D1298,D1481Specific Heat14D2766CategorySectionASTM MethodThermal Conductivity15D2717Turbidity16D6181Viscosity17D88,D445,D2161Electrical Tests:Dielectric Breakdown Voltage18D877,D1816,D3300Dissipation Factor and Rela-tive Permittivity(DielectricConstant)19D924Gassing CharacteristicUnder Thermal Stress20D7150Gassing Tendency21D2300Resistivity22D1169Stability Under ElectricalDischarge23D6180Chemical Tests:Acidity,Approximate24D1534Carbon-Type Composition25D2140Compatibility with Construc-tion Material26D3455Copper Content27D3635Elements by InductivelyCoupled Plasma(ICP-AES)28D7151Furanic Compounds inElectrical Insulating Liquids29D5837Gas Analysis30D3612Gas Content31D831,D1827,D2945Inorganic Chlorides andSulfates32D878Neutralization(Acid andBase)Numbers33D664,D974Oxidation Inhibitor Content34D2668,D4768Oxidation Stability35D1934,D2112,D2440Polychlorinated BiphenylContent36D4059Relative Content ofDissolved Decay37D6802Sediment and Soluble Sludge38D1698Sulfur,Corrosive39D1275Water Content40D1533Specification:Mineral Insulating Oil forElectrical Apparatus41D3487High Firepoint ElectricalInsulating Oils42D52221.4 The values stated in SI units are to be regarded asstandard.The values stated in parentheses are provided forinformation only.1This guide is under the jurisdiction of ASTM Committee D27 on ElectricalInsulating Liquids and Gasesand is the direct responsibility of SubcommitteeD27.01 on Mineral.Current edition approved Sept.15,2010.Published October 2010.Originallypublished as D117 21 T.Last previous edition approved in 2002 as D117 02.DOI:10.1520/D0117-10.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 1.5 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:2D88 Test Method for Saybolt ViscosityD92 Test Method for Flash and Fire Points by ClevelandOpen Cup TesterD97 Test Method for Pour Point of Petroleum ProductsD287 Test Method for API Gravity of Crude Petroleum andPetroleum Products(Hydrometer Method)D445 Test Method for Kinematic Viscosity of Transparentand Opaque Liquids(and Calculation of Dynamic Viscos-ity)D611 Test Methods for Aniline Point and Mixed AnilinePoint of Petroleum Products and Hydrocarbon SolventsD664 Test Method for Acid Number of Petroleum Productsby Potentiometric TitrationD831 Test Method for Gas Content of Cable and CapacitorOilsD877 Test Method for Dielectric Breakdown Voltage ofInsulating Liquids Using Disk ElectrodesD878 Test Method for Inorganic Chlorides and Sulfates inInsulating OilsD923 Practices for Sampling Electrical Insulating LiquidsD924 Test Method for Dissipation Factor(or Power Factor)and Relative Permittivity(Dielectric Constant)of Electri-cal Insulating LiquidsD971 Test Method for Interfacial Tension of Oil AgainstWater by the Ring MethodD974 Test Method for Acid and Base Number by Color-Indicator TitrationD1169 Test Method for Specific Resistance(Resistivity)ofElectrical Insulating LiquidsD1217 Test Method for Density an
