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.
CECC 42 000, test 4.20
1000 h at UCT
After having continuously applied
the maximum allowable voltage at UCT
±2 °C for 1000 h, the specimen shall be
stored at room temperature and normal
humidity for 1 to 2 h.
Thereafter, the change of V
measured.
CECC 42 000, test C 2.1
100 surge currents (8/20 µs), unipolar,
interval 30 s, amplitude corresponding
to derating curve for 100 impulses at
20 µs

100 surge currents (2 ms), unipolar,
interval 120 s, amplitude corresponding
to derating curve for 100 impulses at
2 ms
CECC 42 000, test 4.7
Metal balls method, 2500 V
The varistor is placed in a container
holding 1.6 ±0.2 mm diameter metal
balls such that only the terminations of
the varistor are protruding.
The specified voltage shall be applied
between both terminals of the speci-
men connected together and the elec-
trode inserted between the metal balls.
