Test Methods
Electrical measurements (initial/after tests) shall be conducted at
temperature of 5 to 35 ¡C, relative humidity of maximum 85 %
The voltage between two terminals with the specified measuring
current CmA DC applied is called Vc or VCmA. The measurement
shall be made as fast as possible to avoid heat affection.
The recommended maximum sinusoidal wave voltage (rms) or
the maximum DC voltage that can be applied continuously.
The maximum voltage between two terminals with the specified
impulse current (8/20 µs).
The maximum power that can be applied within the specified
ambient temperature.
Maximum energy at less than ±10 % of varistor voltage change
when the standard impulse (2 ms) is applied one time.
Maximum current at less than ±10 % of varistor voltage change
when impulse current (8/20 µs) is applied two times continuously
with the interval of 5 minutes.

The change of Vc shall be measured after the specified impulse
is applied 10000 times continuously with the interval of 10
seconds at room temperature.
The change of Vc shall be measured after the specified impulse
is applied 100000 times continuously with the interval of 10
