MIL-R-10509J
e. 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 electrical discontinuity of 0.1 millisecond (ms) or greater duration.
f. Measurement after shock: DC resistance shall be measured as specified in 4.7.2.
g. Examination after test: Resistors shall be examined for evidence of mechanical and electrical damage.
4.7.16 Vibration, high frequency (see 3.21). Resistors shall be tested in accordance with method 204 of MIL-STD-202. The following details and exceptions shall apply.
a. Mounting of specimens: Resistors shall be mounted on appropriate jig fixtures with their bodies restrained from movement and their leads supported at a distance of .25 inch (6.35 mm) from the resistor. These fixtures shall be constructed in a manner to insure that the points of the resistor mounting supports will have the same motion as the vibration test table. The fixtures shall also be of a construction that will preclude any resonance in the fixture when subjected to vibration within the test frequency range, and the fixture shall be monitored for these features on the vibration table. Test leads used during this test shall be no larger than AWG size 22 stranded wire, so that the influence of the test lead on the resistor will be held to a minimum. The test lead length shall be no greater than is absolutely necessary. A shielded cable which may be necessary because of the field surrounding the vibration table shall be clamped to the resistor mounting jig.
b. Initial measurement: DC resistance shall be measured as specified in 4.7.2. c. Test condition: B.
d. Direction of motion: In each of two mutually perpendicular directions, one perpendicular and the other parallel to the longitudinal axis of the resistor.
e. Measurements during test: 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 electrical discontinuity of 0.1 ms or greater duration.
f. Measurement after vibration: DC resistance shall be measured as specified in 4.7.2.
g. Examination after test: Resistors shall be examined for evidence of mechanical and electrical damage.
4.7.17 Resistance to solvents (see 3.22). Resistors shall be tested in accordance with method 215 of
MIL-STD-202. The following details shall apply.
a. The marked portion of the resistor body shall be brushed.
b. The number of sample units shall be as specified in table V.
c. Resistors shall be examined for mechanical damage and legibility of markings.
