NONMEMBERAIEE A.P.STI NONMEMB A MINERAL OILinusemustgive *4~satisfactory performance notonly during initial service bujt alsoafter extended periods ofoperation. Itmust possess suitable initial properties and musthavesatisfactory stability toward oxidation. To determine thesuitability ofan electrical oil, ithasbeenthepractice to applyspecific tests toevaluate some critical factor necessary forgoodperformance. Inthis paper, theauthors discusshowthechemical composition ofthe oilaffects itsperformance andinparticular its oxidation stability. Mineral oils arehighly complex mixtures ofhydrocarbons with minor amounts ofnonhydrocarbons. Becauseofthis complexity ithasbeendifficult inthepast torelate composition withperformance, andempirical tests havebeendeveloped overtheyears togive someideaofthe nature ofanoilwithout actually determiningitscomposition. The aniline point, viscosity, specific gravity, pour point, floc point, andanumberofother tests give somegeneral indication ofthe nature ofanoilandmaybecorrelatable withperformance insomeinstances. However, theyareoflittle valuewhen precise composition dataaredesired. TestMethods
