MIL-PRF-7808L §4.4.4 - Storage Stability
We perform oil testing by military specification MIL-PRF-7808, which includes measuring the effect of cold temperature storage on lubricating oil. The lubricating oil is stored in a cold chamber for 6 weeks and is then examined for evidence of crystallization, additive separation, and gelling. MIL-PRF-7808 - Aircraft Turbine Engine Lubricating Oil covers the requirements for two grades of aircraft turbine engine lubricating oil used in specific models of aircraft turbine engines, helicopter transmissions, accessory and auxiliary power units, and other types of equipment that require a synthetic base oil.
We also perform storage stability testing by ASTM D4625, ASTM D5304, FTM 3465, FTM 3467, IP 378, MIL-PRF-3150 §4.5.5, MIL-PRF-7808L §4.4.5, MIL-PRF-83261 §4.4.3, and MIL-PRF-83363 §4.4.2. These different test methods use different instruments or procedures or are used for certain sample types. Click on the test method number to learn more about each test.
