Designation:D528205(Reapproved 2012)Standard Test Methods forCompatibility of Construction Material with Silicone FluidUsed for Electrical Insulation1This standard is issued under the fixed designation D5282;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 These test methods cover screening for the compatibilityof construction materials with silicone fluid for use in electricalequipment.1.2 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.3 This standard does not purport to address all of thesafety problems,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 TesterD445 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 TitrationD828 Test Method for Tensile Properties of Paper andPaperboard Using Constant-Rate-of-ElongationApparatus(Withdrawn 2009)3D877 Test Method for Dielectric Breakdown Voltage ofInsulating Liquids Using Disk ElectrodesD924 Test Method for Dissipation Factor(or Power Factor)and Relative Permittivity(Dielectric Constant)of Electri-cal Insulating LiquidsD974 Test Method for Acid and Base Number by Color-Indicator TitrationD1169 Test Method for Specific Resistance(Resistivity)ofElectrical Insulating LiquidsD1933 Specification for Nitrogen Gas as an Electrical Insu-lating MaterialD2129 Test Method for Color of Clear ElectricalInsulatingLiquids(Platinum-Cobalt Scale)D2225 Test Methods for Silicone Fluids Used for ElectricalInsulationD2413 Practice for Preparation of Insulating Paper andBoard Impregnated with a Liquid DielectricD3612 Test Method for Analysis of Gases Dissolved inElectrical Insulating Oil by Gas ChromatographyD4243 Test Method for Measurement of Average Viscomet-ric Degree of Polymerization of New and Aged ElectricalPapers and BoardsD4559 Test Method for Volatile Matter in Silicone FluidD4652 Specification for Silicone Fluid Used for ElectricalInsulationD5837 Test Method for Furanic Compounds in ElectricalInsulating Liquids by High-Performance Liquid Chroma-tography(HPLC)3.Significance and Use3.1 The magnitude of the changes in the electrical propertiesof the silicone fluid is of importance in determining thecontamination of the fluid by the test specimen.3.2 Physical and chemical changes in the fluid,such as colorand acidity,also indicate solubility or other adverse effects ofthe test specimen on the fluid.3.3 Physical changes of the test specimen,such as hardness,swelling,and discoloration,show the effect of the fluid on thetest specimen and are used to determine the suitability of thematerial for use in silicone fluid.3.4 A material meeting the criteria recommended does notnecessarily indicate suitability for use in electrical equipment.Other properties must also be considered.Additionally,certainmaterials containing additives may meet the requirements ofthese test methods yet be unsatisfactory when subjected tolonger-term evaluations.1These test methods are under the jurisdiction of ASTM Committee D27 onElectrical Insulating Liquids and Gasesand are the direct responsibility of Subcom-mittee D27.06 on Chemical Test.Current edition approved Feb.1,2012.Published February 2012.Originallyapproved in 1992.Last previous edition approved in 2005 as D5282 05.DOI:10.1520/D5282-05R12.2For 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 3.5 These test methods may be used as a guide for testingthe compatibility of materials for silicone fluids other than 50cSt poly-dimethyl siloxane fluid,but different criteria forjudgment may be necessary.4.Apparatus4.1 Sample-Handling Apparatus:4.1.1 Oven,forced draft,adjustable to 120 6 1C,and adrying oven,adjustable to 105 6 5C.4.1.2 Glass Containers,1-L,fitted with glass or aluminumfoil covers(Note 1).NOTE1Other materials have been found to be suitable as covers.4.1.3 Fritted Glass Dispersion Tube(coarse).4.2 Sample-Testing Apparatus:4.2.1 Tensile StrengthAs specified in appropriate testmethod.4.2.2 HardnessAs specified in appropriate test method.4.2.3 Dimensional ChangeMicrom
