Becauseit may not be technically possible to adequetely depict all changes accurately, ASTM recommends that users consult prior editions as appropriate.

6 Summary of Test The test oil, water, and copper catalyst coil, contained in a covered glass container, are placed in a vessel equipped with apressure gage. The vessel is charged with oxygen to a gage pressure of 620 kPa (90 psi, bar) (see Note Eq 1), placed in aconstant-temperature oil bath set at 150 C, and rotated axially at 100 rpm at an angel of 30 from the horizontal. The number ofminutes required to reach a specific drop in gage pressure is the Oxidation Stability of the test sample. NOTE1 100 kPa = = psi(1)4. Significance and The estimate of Oxidation Stability is useful in controlling the continuity of this property for batch acceptance of productionlots having the same operation.

7 It is not intended that this test Method be a substitute for Test Method D 943or be used to comparethe service lives of new oils of different This test Method is also used to assess the remaining Oxidation test life of in-service A modification of the rotating vessel Method has been published as Test Method D 2112, which uses a similar procedure and apparatus buta lower (140 C) bath temperature. Test Method D 2112 requires duplicate testing and Test Method D 2272 conducted duplicate testing in the Vessel, Glass Sample Container with Four-Hole PTFE Disk, Hold-Down Spring, Catalyst-Coil, Pressure Gage,Thermometer, and Test Bath, as described in Annex A1.
