Testing Method
The capacitance should be measured at 20°C with 1±0.1kHz
and AC 1 to 5V(r.m.s.).
The capacitance measurement should be made at each step
specified in table.
Capacitance change from the value of step 3 should not exceed the
limit specified.

The dissipation factor should be measured at 20°C with 1±0.1kHz
and AC 1 to 5V(r.m.s.).
The capacitor should not be damaged when DC voltage of 150% of
the rated voltage is applied between the terminals for 60±5 sec. in
insulating liquid or gas.
(Charge/Discharge current V 50mA)
The insulation resistance should be measured with DC1000V within
60±5 sec. of charging.
When mounting the capacitor on equipment, be sure to mount
them within the torque strength values shown in the table below.

Apply a DC voltage of 125% of the rated voltage for 100+24/-0 hrs. in
silicon oil at 85±2°C.
Post-treatment: Capacitor should be stored for 24 hrs. at *room
condition. (Charge/Discharge current V 50mA)
Set the capacitor for 100+24/-0 hrs. at 40±2°C in 90 to 95% relative
humidity. Post-treatment: Capacitor should be stored for 24 hrs. at
*room condition.
* "room condition" Temperature: 15 to 35°C, Relative humidity: 45 to 75%, Atmospheric pressure: 86 to 106kPa
