1High temp storage test144 hours at + 85 ºCAfter 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 
2Low temp storage test144 hours at - 40 ºC
3High temp and high humidity storage test144 hours at + 65 ºC and 85 ± 5% RH
4Thermal shock testParallel 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 
5Vibration testProducts 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 respectivelyAfter 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 
6Monomer drop test15 free fall tests carried out from 100 ± 10cm height to 50mm thick wooden floorAfter 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
