Degradation Limits of MIL-PRF-5606, MIL-PRF-83282, and MIL-PRF-87257 Hydraulic Fluids Used in Hydraulic Test Stands
|Publication Date:||1 October 2020|
This SAE Aerospace Information Report (AIR) presents data on normally accepted changes in physical properties and contamination levels for MIL-PRF-5606, MIL-PRF-83282, and MIL-PRF-87257 hydraulic fluids used in hydraulic test stands. This information is of importance to all users of hydraulic test stands to assure the performance data obtained on these test stands for specific components will not be adversely affected by excessive changes in fluid properties or contamination levels.
The purpose of this report is to offer guidelines for deciding when the respective fluid has degraded to an extent that warrants replacement in hydraulic test stands. The most sensitive hydraulic components in systems using the subject fluids will dictate the limits of contamination or degradation permitted for each case. The guidelines incorporated in the AIR are the general concerns of knowledgeable professionals. However, the experience and judgment of engineers and operators responsible for the equipment must be relied upon to determine when hydraulic fluid is to be replaced.
