Apply rated voltage (Ur) at 40ºC and / or category

voltage (Uc) at 85ºC for 2000 hours through a

circuit impedance of ≤0.1Ω/V. Stabilize at room

temperature for 1-2 hours before measuring.

Store at 65ºC and 90-95% relative humidity for

500 hours, with no applied voltage. Stabilize at

room temperature and humidity for 1-2 hours

before measuring.

Apply 1.3x rated voltage (Ur) at 40ºCfor 1000

cycles of duration 6 min (30 sec charge, 5 min

30 sec discharge) through a charge / discharge

resistance of 1000Ω
