hydraulic "burst" test
hydraulic "burst" test
(OP)
Can someone please point me in the direction of a standard for hydraulic "burst" testing to be used with a hydraulic ram design?
Requirements call for a 4X 'burst test'- with no references given.
what qualifies passing or failure?
-metal yield?
-seal extrusion?
-seal leakage?
-complete rupture of the cylinder or heads?
There are different opinions as to test procedure. We have seen an example of a 5 minute hold with pressure monitoring, but my feeling is that that the hold time is excessive for a 4X test.
all opinions welcome.

RE: hydraulic "burst" test
...requires a burst pressure of xxxx psi
be applied to the component for a minimum of one minute and then held for one minute. The fluid temperature shall be maximum rated at a maximum rate of increase of
25,000 psi per second.
Success Criteria
Distortion or permanent set may occur; however, neither the internal nor the external components
may rupture nor shall external leakage be evident. There shall be no evidence of structural
failure.

that's very helpful.
