Zusammenfassung:	Effects of Oxygen on grease or another organic paste product can be evaluated with a modified version of the ASTM D942 test methodology for oxidation stability of lubricating greases or other organic paste products by employment of an oxidation pressure vessel, in which at least one of (A) a very small sample of the grease or other organic paste product is deployed for testing within the oxidation pressure vessel such that the sample has an enhanced surface area to mass ratio, and (B) a temperature other than about 99° C. is employed during the testing. In general, the testing is carried out under oxidation pressure conditions. The sample may be evaluated with respect to Oxygen uptake. Additional technique(s) directed to oxidation and/or other properties of the sample may be carried out before to after any Oxygen uptake evaluation, for example, FTIR analysis and/or ATR-FTIR analysis.
