Test methods/conditions
The voltage between two terminals with
the specified measuring current applied
is called V
The maximum voltage between two
terminals with the specified standard
impulse current (8/20 µs) applied.
voltage V
applied for 1000 ±48 h.
The leakage current I
is recorded.
Then the specimen shall be stored at
room temperature and normal humidity
for 1 to 2 h.
Thereafter, the change of V
measured.
10 surge currents (8/20 µs), unipolar,
interval ≥60 s, amplitude correspond-
ing to derating curve for 10 impulses

IEC 60068-2-78
The specimen shall be subjected to
40 ±2 °C, 90 to 95% r. H. for 56 ±2 days
with 10% of the maximum continuous
DC operating voltage V
Then stored at room temperature and
normal humidity for 1 to 2 h.
Thereafter, the change of V
