Test Conditions
20P5C, 65P20% RH unless specified.
However, if it does not affect test result,
the condition can be 20P15C, 65P20% RH also.
The voltage between the two terminals measured at 1mA DC is called Varistor Voltage.
The measurement shall be made as fast as possible to aviod heat effection.
Maximum continuous AC voltage (50K60Hz AC) and maximum DC voltage which can be
applided.
Maximum surge current (8/20MSec. pulse wave to be applied once, or twice, 2 minute apart) for
varistor voltage change within P10% of the initial value.
Maximun energy (2mSec. square wave to be applied once) for varistor voltage change within
P10% of the initial value.
Maximum power (50K60Hz AC power to be applied for 1,000 hours at 85P2C) for varistor
voltage change within P10% of the initial value.
Maximum voltage across varistor when 8/20MSec. rated current surge is applied.

Short circuit the two leads of varistor, and put the varistor body into lead balls (1.6mm
diameter) leaving 2mm epoxy coating outside. Then, apply 2.5kVrms between the leads and
the lead balls for 60P5 seconds.

Test Conditions
Subject varistor to the following tempmrature cycles. -40C for 30 minutes Normal room
temperature for 10 minutes 85C for 30 minutes Normal room temperature for 10 minutes.
This completes one cycle. The cycle shall be repeated 50 times total. After the cycles, the
varistor shall be stored at normal room temperature for one hour. Then check the varistor
voltage and the appearance.
Store varistor at 125C for 1,000 hours. After that, store the varistor at normal room
temperature for one hour. Then check the varistor voltage.
Store at 40C, 90K95% RH for 1,000 hours. After that, store the varistor at normal room
temperature for one hour. Then cheek the varistor voltage.
Apply maximum applied voltage to varistor at 85C for 1,000 hours. After that, store the varistor
at normal room temperature for one hour. Then check the varistor voltage.
