Test Method
As shown in the figure below, the lead wires are immersed in
molten solder up to 1.5 mm (+5/−0 mm) from the end of the
epoxy meniscus (root of lead wire).

Pre-treatment: Capacitor is stored at 85°C ±2°C for 1 hour and
then placed at room condition¹ for 24±2 hours before initial
measurements.
Post-treatment: Capacitor is stored for 1 to 2 hours at room
condition¹.
Capacitor is stored at 120°C +0/−5°C for 60+0/−5 seconds. Then,
as shown in the figure below, the lead wires are immersed in
molten solder up to 1.5 mm (+5/−0mm) from the end of the epoxy
meniscus (root of lead wire).

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°C throughout the test. The capacitors are subjected to
AC 850 Vrms. Each hour the voltage is increased to 1,000 Vrms
for 0.1 seconds. .
