Test Methods/Descriptions
Unless other wise specified, electrical measurements (initial/aftertests) shall
be conducted at temperature of 5 to 35ЊC,relative humidity of 45 to 85%
and atmospheric pressure of 860 to 1060 hPa.
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 maximum sinusoidal RMS voltage or maximum DC voltage that can be
applied continuously in the specified operating temperature range.

The maximum energy within the varistor voltage change of Ϯ10% when a
single impulse current of 2 ms or 10/ 1000s is applied.
The maximum current within the varistor voltage change of Ϯ10% when a
standard impulse current of 8 / 20s is applied two times with an interval of
5 minutes.
The maximum current within the varistor voltage change of Ϯ10% with a
single standard impulse current of 8 / 20s is applied .
