Shenzhen Wuxiang Testing (Group) Co., Ltd. Report No.WUX202110215313UL Dielectric Voltage-Withstand Test (32) Method: The test is made while the EUT is still in well-heated condition Make sure the power switch of the EUT is in ON position. Thin material can be tested in room temperature. The test voltage is a.c. of 50 or 60 Hz or d.c. voltage equal to peak value of the a.c. voltage. Test voltage is applied gradually raised from zero to the specified voltage and held at that value for 60s.
