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.

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.
