MIL-PRF-83530C
4.8.23 Operating life (see 3.28). Resistors shall be tested in accordance with method 108 of MIL-STD-202. The
following details and exceptions shall apply:
a.
If forced-air circulation is employed, there shall be no direct impingement of the forced-air supply upon the
parts.
b.
Resistors shall be mounted by their normal mounting means and shall be so spaced to minimize the
temperature of one specimen affecting the temperature of another.
Temperature - 85OC ±2OC.
c.
Operating conditions - The rated ac input voltage and frequency shall be applied (see 3.1).
d.
e.
Test condition - D.
Measurements after test - Nominal voltage and clamping voltage shall be measured as specified in 4.8.2 and
f.
4.8.3 respectively.
g.
Examination after test - Resistors shall be visually examined for evidence of mechanical damage.
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 activity 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: 20 G's of high
frequency vibration, 100 G's of shock (specified pulse), thermal shock (with no more than 1 percent deviation in initial
resistance), and a low temperature coefficient of resistance. In addition, these military requirements are verified
under a qualification system. Commercial components are not designed to withstand these military environmental
conditions.
6.2 Ordering data. Acquisition documents must specify the following:
a.
Title, number, and date of this specification, and the complete PIN (see 1.2).
If not otherwise specified (see 2.1), the versions of the individual documents referenced will be those in
b.
effect on the date of release of the solicitation.
c.
Packaging instructions (see 5.1).
