Time
Capacitors are placed in a circulating air oven for a period of
1,000 hours. The air in the oven is maintained at a temperature of
125°C ±2 throughout the test. The capacitors are subjected to AC
510 Vrms. Each hour the voltage is increased to 1,000 Vrms for
0.1 seconds.
The capacitor is exposed to a flame for 15 seconds and then
removed for 15 seconds. This test is repeated for 5 cycles.

The capacitors are individually wrapped in at least one, but not
more than two, complete layers of cheesecloth. They are then
subjected to 20 discharges. The interval between successive
discharges is 5 seconds. The VAC is maintained for 2 minutes
after the last discharge.
