Life test

External appearance

No visible damage.

The marking shall be legible.

Impulse voltage: each individual capacitor

shall be subjected to a 10 kV impulse for

ten times each polarity. Before the

capacitors are applied to life test.

The specimen capacitors shall be

submitted to an endurance test of

1000 h + 48 h / - 0 h in a chamber at

Pre-treatment: capacitor shall be backed

at 125 °C ± 3 °C for 1 h before initial

measurements.

Post-treatment: capacitors shall be

placed at room condition for 24 h ± 2 h

before measurements.

Capacitance change
