| Items | Test Method | Standard |
| DC Spark-over Voltage | Measure starting discharge voltage (Vs) by gradually increasing applied DC voltage. Test current is 0.5mA max. And the DC voltage ascends up within 100V/s(Vs＜1000V) or 500V/s(Vs≥1000V). | Rate-of-change, within±30% insulation resistance & capacitance, conformed to rated spec. |
| Insulation Resistance | Measure the insulation resistance across the terminal at regular voltage. But the test voltage doesn’t over the DC spark-over voltage. | |
| Capacitance | Measure the electrostatic capacitance by applying a voltage of less than 6V (at 1KHz) between terminals. | |
| Static Life | 10KV with 1500pf condenser is discharged through 2KΩ resistor. 200 times at an interval of 10sec. | ∣△Vs/Vs∣≤30% Characteristics of other items must meet the specified value |
Surge Current Capacity | 1.2/50μs & 8/20μs, 1000A, electrically connected with a resistor (1~2 Ω), ±5 times, each time interval 60 seconds. Thereafter, outer appearance shall be visually examined. | No crack and no failures |
| Cold Resistance | Measurement after -40℃/1000 HRS & normal temperature/2 HRS. | Features are conformed to rated spec |
| Heat Resistance | Measurement after 125℃ /1000 HRS & normal temperature/2 HRS. | |
| Humidity Resistance | Measurement after humidity 90~95℃(45℃ ) /1000 HRS & normal temperature/2 HRS. | |
| Temperature Cycle | 10 times repetition of cycle -40℃ /30min →normal, temp/2 min →125℃/30min, measurement after normal temp/2 HRS. | |
| Solder Ability | Apply flux and immerse in molten solder 230±5℃ for 3sec up to the point of 1.5mm from body. Check for solder adhesion. | Lead wire is evenly covered by solder |
| Solder Heat | Measurement after lead wire is dipped up to the point of 1.5mm from body into 260±5℃ solder for 10sec | Conformed to rated spec |
| Pull Strength | Apply 0.5kg load for 10sec | Lead shall not pull out to snap |
| Flexural Strength | Bend lead wire at the point of 2mm from body under 0.25 load and back to its original point. Repeat 1 time. |
| DC Spark-over Voltage | Measure starting discharge voltage (Vs) by gradually increasing applied DC voltage. Test current is 0.5mA max.
