MIL-PRF-39009E
with the following exceptions:
a. Test condition A (Pull test). Applied force: As specified (see 3.1). Resistor body firmly clamped
and pull applied to hole of each terminal for at least 30 seconds, one terminal at a time, in a
direction away from resistor and parallel to the longitudinal axis.
b. Measurement before and after test: DC resistance as specified in 4.8.3.
c.
Examination after test: Resistors shall be examined for evidence of mechanical damage.
4.8.11 Shock (specified pulse) (see 3.17). Resistors shall be tested in accordance with method 213 of
MIL-STD-202. The following details shall apply:
a. Special mounting means: Resistors shall be mounted by their normal mounting means on a
vibration test jig. The jig shall be constructed as to preclude any resonances within the test range.
Resistors shall be vibrated so that 12 cycles are performed in each of three mutually
perpendicular directions (total of 36 times).
b. Test condition I.
c.
Measurement before shock: DC resistance shall be measured as specified in 4.8.3.
d. Measurement during shock: Each resistor shall be monitored to determine electrical discontinuity
by a method which shall at least be sensitive enough to monitor or register automatically any
discontinuity having a duration of 0.1 millisecond as well as those of greater duration.
e. Measurement, examination, and test after shock: DC resistance shall be measured as specified
in 4.8.3. Resistors shall be examined for evidence of mechanical damage. Resistors shall then
be subjected to the dielectric withstanding voltage test (at atmospheric pressure) as specified in
4.8.12 Vibration, high frequency (see 3.18). Resistors shall be tested in accordance with method 204 of
MIL-STD-202. The following details and exceptions shall apply:
a. Mounting specimens: Resistors shall be mounted by their normal mounting means on a vibration
test jig. The jig shall be constructed as to preclude any resonances within the test range.
Resistors shall be mounted in relation to the test equipment in such a manner that the stress
applied is in the direction which would be considered most detrimental.
b. Test condition: D (0.06 inch (1.5 mm) double amplitude or 20G).
Measurement during vibration: DC resistance shall be measured as specified in 4.8.3.
c.
d. Measurement during vibration: Each resistor shall be monitored to determine electrical
discontinuity having a duration of 0.1 millisecond as well as those of greater duration.
e. Measurement, examination, and test after vibration: DC resistance shall be measured as
specified in 4.8.3. Resistors shall be examined for evidence of mechanical damage. Resistors
shall then be subjected to the dielectric withstanding voltage test (at atmospheric pressure) as
specified in 4.8.5.1.
