Shelf Life

The following specifications shall be satisfied when the capacitors are restored to

20 C after

exposing them for 1,000 hours at

105 C without voltage applied. The rated voltage shall be

applied to the capacitors for a minimum of 30 minutes, at least 24 hours and not more than

48 hours before the measurements.
