3.3.2 Test method: Use a discharge device to apply a DC voltage between the specified contact and the ground terminal. The contact is connected to the positive pole and the ground terminal is connected to the negative pole. The voltage is gradually increased until the discharge is completed. The voltage indication accuracy of the discharge device is 15%, and the discharge current is 1mA. The environmental conditions for the discharge test are: temperature 20℃ 5℃, relative humidity 45%~75%.
3.4 Discharge durability
3.4.1 Requirements: The socket is subjected to 5000 discharge tests between the specified contact and the ground terminal at the specified upper limit of the starting discharge voltage. After the test, there should be no mechanical damage, and the starting discharge voltage range should comply with Table 23.4.2 Test method: Test on a discharge durability test equipment that complies with the circuit principle of Figure 3. The contact is connected to the positive pole and the ground terminal is connected to the negative pole. Discharge once in about 1 second times, the discharge current should be 1mAR
Can be directly connected to the power supply
