3.Environmental test

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 pin for 30 seconds	The pin 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 probe from the water and install it on the test board to measure the distance. The probe works normally without long sound.
