Detection and determination of specified anti-oxidant additives in insulating oils.
Detection and determination of specified anti-oxidant additives in insulating oils
Determination of the aromatic hydrocarbon content of new mineral insulating oils
1.1 These test methods cover testing synthetic dielectric fluids currently in use for capacitors. The methods are generally suitable for specification acceptance, factory control, referee testing, and research. Their applicability to future fluids has not been determined.1.2 The scope of some of the test methods listed here apply to petroleum oils, but have been found suitable for synthetic fluids.1.3 For methods relating to polybutene fluids refer to Specification D2296.1.4 For methods relating to silicone fluids refer to Test Methods D2225.1.5 A list of properties and standards are as follows:Property MeasuredSectionASTM Test MethodPhysical:Coefficient of thermal expansion6D 1903Flash point7D 92Pour point8D 97Refractive index9 D 1218Relative Density/Specific gravity10 D 1298Viscosity11D 445Chemical:Acid number12D 664Water content13D 1533Electrical:Relative permittivity14 D 924Dielectric strength15D 877D 1816Dissipation factor16D 9241.6 This standard does not purport to address all of the safety problems, if any, associated with its use.
