This apparatus measures the net change in pressure resulting from consumption of oxygen by oxidation and gain in pressure due to formation of volatile oxidation by-products. It predicts neither the stability of greases under dynamic service conditions, nor the stability of greases stored in containers for long periods, nor the stability of films of greases on bearings and motor-parts. It should not be used to estimate the relative oxidation resistance of different grease types.

Overview
HK-0325 Greases Oxidation Stability apparatus conforms to the ASTM D942 Standard Test Method for Oxidation Stability of Lubricating Greases by the Oxygen Pressure Vessel Method, This apparatus determines resistance of lubricating greases to oxidation when stored statically in an oxygen atmosphere in a sealed system at an elevated temperature under conditions of test
