MIL-DTL-8795G
4.5.4 Leakage test (see 3.3.4). Hose assemblies when subjected to the leakage test shall meet the
requirements of 3.3.4. The following details shall apply:
a. The hose assemblies shall be subjected to 70 percent of the burst pressure specified in table I
for 5 minutes.
b. The pressure shall then be reduced to 0 pounds per square inch (psi), after which it shall be
raised to 70 percent of the specified burst pressure for a final 5-minute check.
4.5.5 Burst pressure test (see 3.3.5). Hose assemblies shall be subjected to the burst pressure
a. Testing shall be performed within 45 days after assembly of the adapters to the hose.
b. The burst pressure test shall be conducted in accordance with the straight bursting test in
accordance with ASTM D380, except that pressure shall be applied at a rate between 15,000
and 25,000 psi per minute (103.4 to 172.4 MPa per minute).
c. During this test, one end of the test article shall be free.
d. The hose assembly shall not burst, and there shall be no evidence of leaking or separation of
the hose from adapter, at pressures up to the burst pressure in table I.
5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the
contract or order (see 6.2). When packaging of materiel is to be performed by DoD or in-house
contractor personnel, these personnel need to contact the responsible packaging activity to ascertain
packaging requirements. Packaging requirements are maintained by the Inventory Control Point's
packaging activities within the Military Service or Defense Agency, or within the military service's system
commands. Packaging data retrieval is available from the managing Military Department's or Defense
Agency's automated packaging files, CD-ROM products, or by contacting the responsible packaging
activity.
6. NOTES
(This section contains information of a general or explanatory nature that may be helpful, but is not
mandatory.)
6.1 Intended use. These hose assemblies are for use in aircraft hydraulic, fuel, and oil systems
operating in an environment from -65°F to 160°F (-53.9°C to 71°C), and in oil systems sizes -3 through -
12 operating in an environment from -65°F to 250°F (-53.9°C to 121°C) (see MIL-DTL-8794). The hose
assemblies covered by this specification are intended for use in medium pressure applications in
hydraulic, fuel, and oil systems of aircraft. Size -3 hose assemblies are not to be used in hydraulic
applications (see table I).
6.1.1 Military unique rationale. The rubber hose assemblies described by this specification must be
capable of interoperability and compatibility which can only be assured through strict adherence to the
detail specification sheet requirements and this specification. Commercial parts are not designed to be
interchangeable with aircraft hydraulic systems.
6.2 Acquisition requirements. Acquisition documents should specify the following:
a.
Title, number, and date of the specification.
Title, number, and date of the applicable specification sheet and the complete PIN (see 1.2).
b.
c.
Level of preservation, packaging, and marking required (see section 5.1).
d.
Shelf life requirements (see 6.2.1).
