MIL-PRF-18546G

4.7.12 Shock (specified pulse) (see 3.16). Resistors shall be tested in accordance with method 213,

condition I, of MIL-STD-202. The following details shall apply:

a. Mounting: Resistors shall be mounted by their normal mounting means as specified in 4.7.11.1 on

an appropriate mounting fixture. The mounting fixture shall be constructed in such a manner as to

insure that the mounting supports remain in a static condition with reference to the shock table.

Resistors shall be mounted in such a manner that the stress applied is in the direction which would

be considered most detrimental.

b. Test condition: I

c. Measurement before shock: Resistance as specified in 4.7.2.

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 as duration of 0.1 millisecond as well as those of greater duration.

e. Measurement inspection, and test after shock: Resistance (see 4.7.2) shall be measured, and the

resistors inspected for evidence of mechanical damage. Resistors shall be subjected to the

dielectric withstanding voltage test (at atmospheric pressure) as specified in 4.7.6.1.

4.7.13 Vibration, high frequency (see 3.17). Resistors shall be tested in accordance with method 204

of MIL-STD-202. The following details shall apply:

a. Mounting: Resistors shall be mounted by their normal mounting means as specified in 4.7.11.1 on

a vibration test jig. The jig shall be so constructed so as to preclude any resonance 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: B.

c. Measurements before vibration: Resistance as specified in 4.7.2.

d. Measurements during vibration: 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 or less, as well as those of

greater duration.

e. Measurements, inspection, and test after vibration: Resistance (see 4.7.2) shall be measured,

and the resistors inspected for evidence of mechanical damage. Resistors shall then be subjected

to the dielectric withstanding voltage test (atmospheric pressure) as specified in 4.7.6.1.

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 Department 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.
