f.
Proof Testing of Flexible Hose Assemblies. All field fabricated hose assemblies which have passed the
visual inspection shall be proof tested. Hose assemblies drawn from stock shall be inspected for defects such as
mishandling damage and proper banding and proof tested if necessary (refer to tables 4-16, 4-17, 4-18, and 4-19).
(1)
Test hose assemblies to be used in hydraulic, pneumatic, fuel, oil, and coolant applications using a
hydrostatic test unit filled with hydraulic fluid conforming to MIL-H-5606 for MIL-H-6083, lubricating oil MIL-L-6082, or
water.
(2)
Test hose assemblies to be used in instrument applications using dry, oil-free air or nitrogen, Federal
Specifications BB-N-411, Grade A, Type 1.
(3)
Connect hose assembly to be tested to hydrostatic test unit, air supply, or nitrogen supply as
