Assemblies having aluminum flange fittings shall be pressure tested at the rated proof pressure or 1,500 psig,
whichever is less.
2 Hold proof-test pressure for not less than 30 seconds nor more than 5 minutes
appropriate and apply correct pressure for hose assembly being tested. Proof pressure for MS28759 and MS28762 hose
assemblies are shown in table 4-15. Proof pressures for MS28741 hose assemblies are shown table 4-16. Proof
pressures for MIL-H-83796 are shown in table 4-17. Proof pressures for MIL-H-83797 hose are shown in table 4-18.
Proof pressures for AN6270 hose assemblies are shown in table 4-19. The torque to apply to the swivel nut of the hose
assembly when installing on adapter ends is given In table 4-20.
WARNING
Hoses to be tested shall be securely restrained to prevent whipping in case the fittings should blow off.
Longer hoses should have several restraints. The test is best conducted with hose in an enclosure having
a heavy transparent plastic cover which can be fastened closed. Personnel shall wear eye and face
protection.
(4)
Observe all hose assemblies proof tested with a liquid test medium for leakage from hose or around
fittings. Apply proof pressure for not less than 30 seconds and not more than 5 minutes.
