Test withstand voltage testwithstandvoltage

Under specified conditions, the test voltage value of the standard waveform: When a new valve in good condition is applied for the specified number of times or for the specified duration

When this test voltage is applied for a period of time, no destructive discharge occurs and all other acceptance criteria specified for the particular test are met:
