MIL-PRF-32033 § - Film Characteristics/High Temperature Stability

We perform oil testing by military specification MIL-PRF-32033, which includes testing the high temperature stability of water-displacing lubricating oil. This test determines whether the oil sample becomes gummy, tacky, or hard when subjected to a temperature of 100C for 24 hours. A glass slide is coated with the sample and then is drained at a 45 degree angle for 24 hours at room temperature to remove any excess oil. The glass slide is then stored in an oven at 100C for 24 hours. MIL-PRF-32033 - Lubricating Oil Specification covers a general purpose preservative lubricating oil used in low temperature applications.

We also perform thermal stability testing by ASTM D2070ASTM D6468ASTM E487ASTM E537FTM 3411FTM 3458FTM 3459IP 467MIL-H-22072 §4.6.3MIL-PRF-3150 §4.5.4MIL-PRF-372E § §, and MIL-PRF-87252 §4.5.5. These different test methods use different instruments or procedures or are used for certain sample types.
