Solder the capacitor to the test jig (glass epoxy board) in the
same manner and under the same conditions as (19). 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 2000Hz. The
frequency range, from 10 to 2000Hz and return to 10Hz, should
be traversed in approximately 20 minutes. This motion should be
applied for 12 items in each 3 mutually perpendicular directions
(total of 36 times).

measure.
• Initial measurement for high dielectric constant type
Perform a heat treatment at 150^W Y⁰ 10°C for one hour and then let
sit for 24±2 hours at room temperature.
Perform the initial measurement.
