SAE J1333:2020 pdf free.Hydraulic Cylinder Rod Corrosion Test
The length of stroke for the operational test shall be equal to at least 15% of the maximum stroke length of the hydraulic cylinder.
Use a suitable test fixture, for example, an oscillating beam type, a conventional in-line beam type, or similar fixture, in which the test cylinder can be loaded and driven in either direction under both static and dynamic conditions with a side load.
Connect test cylinder to a fluid power source and cycle at maximum stroke a minimum of 20 cycles to displace the trapped air and install it in the cycle test stand.
Cycle the cylinder against the side load for 1000 cycles and perform a 1000 cycle rod seal dynamic leakage test in accordance with SAE J1336.
Remove the cylinder from the test fixture. In a fully extended position, prepare the rod surface as defined in ASTMB 117 or ASTM B 368. Subject the fully extended rod to a salt- fog environment in accordance with the selected test for 24 h minimum, unless otherwise specified. Define the rod surface condition at completion of exposure in accordance with the selected test method. Use photographs as required.
Following exposure test, do not clean rod. Reinstall cylinder (do not clean rod) in same fixture used for 6.2. Cycle the cylinder against the side load at rated conditions for 10 000 full stroke cycles.
Perform a rod seal dynamic leakage test in accordance with SAE J1336 during the final 1000 cycles.
Record the test used, exposure duration, and rod seal dynamic leakage cofficients in accordance with SAE J1336.
