Test Condition / Description

Requirement

DC Spark-over

Voltage

The voltage is measured with a slowly rate of rise dv / dt=100V/s

To meet

the specified

value

Impulse

Spark-over

Voltage

The maximum impulse spark-over voltage is measured with a rise time of

dv / dt=100V//μs or 1KV/μs

Insulation

Resistance

The resistance of gas tube shall be measured each terminal each other terminal, please

see above spec.

Capacitance

The capacitance of gas tube shall be measured each terminal to each other terminal.

Test frequency :1MHz

Nominal Impulse

Discharge

Current

The maximum current applying a waveform of 8/20μs that can be applied across the

terminals of the gas tube. One hour after the test is completed, re-testing of the DC

spark-over voltage does not exceed ±30% of the nominal DC spark-over voltage. Dwell time

between pulses is 3 minutes.

Nominal

Alternating

Discharge

Current

Rated RMS value of AC current at 50Hz, 1 sec. 10 times. Intervals: 3min. The DC

spark-over voltage does not exceed ±30% of the nominal DC spark-over voltage.

Solder Iron Temperature: 350°C +/-5°C

Heating Time: 5 seconds max.
