Patent number: 8021885Abstract: The present invention concerns a method for the determination of the oxidative stability of a lubricating fluid, comprising the steps of: introducing a sample of the lubricating fluid under test in an reaction cell; introducing catalytic amounts of a catalyst to the reaction cell; heating the cell to the oxidation temperature of the lubricating fluid and maintaining this temperature; delivering oxygen containing gas at constant flow rate through the cell over the course of the reaction; delivering a gas comprising nitrogen dioxide at a constant flow rate through the cell for a specified time; applying and maintaining a specified vacuum on the reaction cell; allowing the mixture to react for a specified time; measuring the viscosity of the oxidized lubricating fluid. Additionally, the present invention describes an apparatus for the determination of the oxidative stability of a lubricating fluid.Type: GrantFiled: October 11, 2006Date of Patent: September 20, 2011Assignee: Evonik Rohmax Additives GmbHInventors: Bernard Kinker, Raymond Romaszewski
