Solder the capacitor to the test jig (glass epoxy board).
The capacitor should be subjected to a simple harmonic motion
having a total amplitude of 1.5mm, the frequency being varied
uniformly between the approximate limits of 10 and 55Hz. The
frequency range, from 10 to 55Hz and return to 10Hz, should be
traversed in approximately 1 min. This motion should be applied
for a period of 2 hrs. in each of 3 mutually perpendicular
directions (total of 6 hrs.).

Solder the capacitor to the testing jig (glass epoxy board) shown
in Fig. 2.
Then apply a force in the direction shown in Fig. 3. The soldering
should be done using the reflow method and should be
conducted with care so that the soldering is uniform and free of
defects such as heat shock.
