After the test is complete, the stand is stopped by
slowly opening the outlet valve and decreasing the
pressure with the pressure regulator. When the fluid
pressure gauge reads zero, the Plexiglas cover may be
raised, and the test hose is disconnected and removed.
AIRCRAFT HYDRAULIC HOSE BURST
TEST STAND (CGS SCIENTIFIC CORP)
The hose burst test stand, shown in figure 5-18, is
manufactured by CGS Scientific Corporation. This
test stand provides a means for pressure testing of
aircraft hose assemblies of various lengths and sizes.
Hydraulic pressure up to 15,000 psi and pneumatic
pressure up to 1,500 psi are available for the testing of
The test stand is a completely
self-contained unit mounted on legs that permits
bolting to the deck.
Access doors and removable
panels provide easy access to all components for
Figure 5-19 shows the controls and
