| No. | Test items | Test condition | Standard | |||
| 1 | High temp storage test | 144 hours at + 85 ºC | After the test and place in + 25 ºC (room temp) for 24 hours, the sensitivity and residual vibration change shall not exceed 30% compared with the initial value | |||
| 2 | Low temp storage test | 144 hours at - 40 ºC | ||||
| 3 | High temp and high humidity storage test | 144 hours at + 65 ºC and 85 ± 5% RH | ||||
| 4 | Thermal shock test | Parallel 3.9k Ω resistor at both ends of the probe, keep the temp at - 40 ± 5 ºC for 0.5h, and increase the temp to 85 ± 5 ºC within 5 minutes and keep for 0.5h.100 cycles. | After the test and place in + 25 ºC (room temp) for 24 hours, the sensitivity and residual vibration change shall not exceed 30% compared with the initial value | |||
| 5 | Vibration test | Products bear the vibration with frequency 10-55hz, amplitude 1.5mm,and sweep rate 1oct / min, from X, Y and Z directions for each 2 hours respectively | After the test and place in + 25 ºC (room temp) for 4 hours, the sensitivity and residual vibration change shall not exceed 30% compared with the initial value | |||
| 6 | Monomer drop test | 15 free fall tests carried out from 100 ± 10cm height to 50mm thick wooden floor | After the test and place in + 25 ºC (room temp) for 4 hours, the sensitivity and residual vibration change shall not exceed 30% compared with the initial value | |||
| 7 | Strength test of outlet | Apply 9.8N pulling force between shell and wire for 30 seconds | The wire is not loose or falling off, the product function is normal, and the wire is not damaged | |||
| 8 | Protection level | Place the probe in 15cm deep water and soak for 24 hours | Take out the capasual from the water and install it on the test board to measure the distance. The probe works normally without long sound. | |||
| 9 | High and low temp characteristic test | Keep the temp at -40ºC for 2h,increase to 25ºC and keep for 2h,increase to 85ºC and keep for 2h. | After the test and place in + 25 ºC (room temp) for 2 hours, the sensitivity and residual vibration change shall not exceed 30% compared with the initial value | |||
