specimen shall be stored at room temperature and humidity for one or two hours, the change of varistor

voltage shall be within 10﹪.

The specimen should be subjected to 40 ± 2℃, 90 to 95 ﹪RH environment , and the maximum allowable

voltage applied for 1000 hours, then stored at room temperature and humidity for one or two hours. the

change of varistor voltage shall be within 10﹪

The specimen should be subjected to 40 ± 2℃, without load for 1000 hours and then stored at room

temperature for one or two hours. the change of varistor voltage shall be within 10 ﹪
