Test Method
The capacitor should be fully immersed, unagitated, in
reagent at 20 to 25˚C for 30T5 sec. and then remove
gently. Marking on the surface of the capacitor should
immediately be visually examined.

• Initial measurement for high dielectric constant type
A voltage treatment should be given to the capacitor in
which a DC voltage of 200% of the rated voltage is
applied for 1 hr. at the maximum operating temperature
T3˚C. Then set for 48T4 hrs. at room temperature and
conduct initial measurement.
