continuous operation at room temperature
(+25±10oC)
After the test the part shall meet specifications
without any degradation in appearance and performance except SPL. after 4 hours at +25oC,The
SPL would be in ±10dBA compared with initial
one.
HIGH TEMPERATURE
The part will be subjected to 72 hours of continuous operation at +60oC with 3.0V , 2000Hz
applied.
LOW TEMPERATURE
The part will be subjected to 72 hours of continuous operation at -20oC with 3.0V, 2000Hz
applied.

test condition
evaluation standard
solderability
Lead terminal are immersed in rosin for 5
seconds and then immersed in solder bath of
+250±5oC for 3±0.5 second
90% min.lead terminals will be wet with solder
No interference in operation.
soldering heat resistance
Lead terminal are immersed in soldering bath of
+250±5oC for 3±0.5 second.
terminal mechanical
strength
Apply the terminal with 1 KG tension for 1
minute.
No damage and cutting off
vibration
The part will be subjected to a vibration cycle of
10Hz to 55Hz to 10Hz in a period of 1 minute.
Total peak amplitude will be 1.52mm(9.3G). The
vibration test will consist of 2 hours per axis in
each three axes (X,Y,Z), total 6 hours.
After the test the part will meet specifications
without any damage in appearance and performance except SPL. SPL would be in ±10dBA
compared with initial one.
drop test
The part only will be dropped from a height of
75cm onto a 40mm thick wooden board 3 times
in 3 axes (X,Y,Z),(a total of 9 times).
