After an application of DC bias voltage plus the rated AC ripple current for 12000 hours at 105 C.
The measurement shall meet the following limits. The DC voltage plus the peak AC voltage
combined must not exceed the rated voltage.

Less than specified value
Within 20% of initial value
Less than 200% of specified value
Shelf life (at 105°
C)
After 1000 hours no load test, leakage current, capacitance and tan are same as load life value.
The measurement shall be performed at 20 C by the KS C 6035 clause 5.4.
