The measured and observed characteristics should satisfy the
specifications in the following table.
Fix the capacitor to the supporting jig in the same manner and
under the same conditions as (10). Perform the five cycles
according to the four heat treatments listed in the following
table. Let sit for 24±2 hours (temperature compensating type)
or 48±4 hours (high dielectric constant type) at room
temperature, then measure.
