1 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.
3 -54 °C to 121 °C.
NOTE
Tighten cap on hose assembly only after all trapped air has bled from line.
(5)
Immerse all hose assemblies proof tested with a gas test medium in water and observe for leakage
from hose or around fittings. Apply proof pressure for not less than 30 seconds and not more than 5 minutes.
NOTE
On hose having a braided cover, do not confuse entrapped air with leakage. Agitate hose assembly under
water to remove surface bubbles.
(6)
Reject hose assemblies showing evidence of leakage.
