Abstract

MÉTODO PARA DETERMINAÇÃO DA ESTABILlDADE OXIDATIVA DE UM FLUIDO LUBRIFICANTE. A presente invenção refere-se a um método para determinação da estabilidade oxidativa de um fluido lubrificante, contendo as etapas de: introduzir uma amostra do. fluido lubrificante em teste em uma célula de reação; reação; introduzir quantidades catalíticas de um catalisador na célula de aquecer a célula à temperatura de oxidação do fluido lubrificante e manter esta temperatura; distribuir um gás contendo pxigênio a uma vazão constante atrai vés da célula no curso da reação; distribuir um gás contendq dióxido de nitrogênio a uma vazão constante através da célula por um tempo especificado; aplicar e manter um vácuo especificado na célula de reação; permitir que a mistura reaj~ por um tempo especificado; medir a viscosidade do fluido lubrificante oxidado. Adicionalmente, a presente invenção descreve um aparelho para determinação da estabilidade oxidati,va de um fluido lubrificante.
