MIL-PRF-25435D
4.5.21 Overpressure. The pressure required to produce full scale deflection of the standard
indicating unit shall be determined. The transmitter shall have pressure and power connections
made to simulate operational conditions and shall be connected to the standard indicating unit.
The transmitter shall be subjected to 100% overpressure for 10 minutes. During this 10-minute
period, the standard indicating unit reading shall not exceed 105 to 130% of full scale deflection.
One hour after completion of this test, the transmitter shall be subjected to the scale and friction
error test (4.5.3) using only increasing pressure.
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. The transmitters covered by this specification are intended for use with
variable-reluctance-type indicators conforming to MIL-I-25437 in providing remote indication of
aircraft pressure functions.
6.2 Acquisition requirements. Acquisition documents should specify the following:
a. Title, number, and date of this specification.
b. When first article inspection is required (see 3.1).
c. Test points and allowable scale and friction errors (4.5.3)
d. Position error tolerance (4.5.4).
e. Data required.
f. Packaging (see 5.1).
g. Item identification.
