ASTM WK31233

    New Test Method for Oxidation Resistance of Biodegradable Lubricating Fluids Without the Addition of Water (DRY TOST)

    (What is a Work Item?)

    Developed by Subcommittee: D02.N0.03 | Committee D02 | Contact Staff Manager


    1. Scope

    This test will be used to evaluate the oxidation resistance properties of a lubricating fluid in the same way that ASTM D943 is used only excluding water.

    As many of these fluids are natural or synthetic esters, they are sensitive to hydrolysis as well as oxidation. As such, they do not perform well in the traditional oxidation tests that frequently include water as a catalyst. Therefore, the water element has been removed in order to evaluate oxidation of these fluids while excluding the contribution due to hydrolysis.
