| ITEM | TESTING CONDITION | VARIANCE AFTER TEST |
|---|---|---|
High Temperature Test |
After being worked in a chamber at +70±2℃ for 2h and then being placed in natural condition for 2h,sounder shall be measured. |
After test,the transducr S.P.L.difference shall be within ±10dB,and the appearance not exist any change to be harmful to normal operation(e.g.cracks,rusts,damages and especially distortion) |
Low Temperature Test |
First being worked in a chamber at -30 ± 2 ℃ for 2h and then being planed in a chamber at -30±2℃ for16h,finally being placed in natural condition for2h,sounder shall be measured. |
|
Humidity Test |
After being placed in a chamber with 90 to 95%R.H.at+40 ± 2 ℃ for 48h and then being placed in natural condition for 2h,sounder shall be measured. |
|
Vibration Test |
Sounder shall be measured after being applied vibration of amplitude of 0.75mm with 10 to30 to10Hz band of vibration frequency to each of 3 perpendicular directions for 1hour. |
|
Freely Falling Test |
Sounder shall be measured after freely falling the products from 0.8m high to the wooden board with three sides per time. |
|
Collision Test |
Sounder shall be measured after the test of acceleration 100 ± 10m/s²,impulse lasting time 16ms,repeat frequency 1~3/min and time 1000±10. |
|
Solderability |
Lead terminals are immersed in rosin for 3 seconds and then immersed in solder bath at +250 ± 5 ℃ for 3 ± 0.5 seconds,terminals should be covered with the clean solder. |
|
Terminal Strength Pulling |
The force 10 seconds of 1N is applied to each terminal in axial direction.no looseness and falling off. |
