MIL-PRF-22E
4.7.14.3 Measurements during acceleration. As specified in 4.7.13e.
4.7.14.4 Measurement and examination after acceleration test. As specified in 4.7.13f.
4.7.15 Vibration, high frequency (when applicable).Resistors shall be tested in accordance with method 204 of
MIL-STD-202 (see 3.18). The following details and exceptions shall apply:
a. Mounting of resistors: As specified in 4.7.13a.
b. Measurements prior to vibration: As specified in 4.7.13b.
c. Test condition: B.
d. Measurement during vibration: As specified in 4.7.13e.
e. Direction of motion: As specified in 4.7.13d.
f. Measurements and examination after vibration: As specified in 4.7.13d.
4.7.16 Fungus. Resistors shall be tested in accordance with method 508 of MIL-STD-810. Resistors shall be
examined for evidence of mechanical damage (see 3.3.1).
5. PACKAGING
5.1 Packaging. For acquisition purpose, 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 services 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 resistors covered by this specification are military unique due to the fact that these devices
must be able to operate satisfactorily in military systems under the following demanding conditions: 15 g s of high
frequency vibration, 50 g s of shock (specified pulse), 50 g s of acceleration and resistant to salt corrosion. In
addition, these military requirements are verified under a qualification system. Commercial components are not
designed to withstand these military environmental conditions.
6.2 Acquisition documents. Acquisition documents should specify the following:
a. Title, number, and date of this specification.
b. Title, number, and date of the applicable detail specification, and complete PIN (see 1.2.1 and 3.1).
c. If not otherwise spcified, the version of the individual documents referenced wil be those in effect on the sate
of the solicitation (see 2.1).
d. Hardware, whether assembled on resistor (see 3.4.9).
e. Packaging requirements (see 5.1)
