Initial measurements prior to test shall be

made after the voltage pre-conditioning

specified in Remarks (2).

Final measurements shall be made after

the specimens have been left at room

temperature

[Remarks]

Pre-conditioning

If specified in test method of as per 3(Performance and test method), capacitors of CN, FN

characteristics shall be pre-conditionded as follows.

(1) Thermal pre-conditioning

Prior to initial measurements, specimens shall be conditioned at a temperature of 150 0

/−10

°C

for a period of 1hr., and shall be allowed to stabilize at room temperature for 48
