operating life test
test conditions
CONTINUOUS LIFE TEST
48hours of continuous operation at +55oC with
maximum rated voltage applied.
INTERMITTENT LIFE TEST
A duty cycle of 1 minute on, 1 minutes off,
a minimum of 1000 times at room temp,
(+25±2oC) and maximum rated voltage applied
evaluation standard
After the test the part will 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.
TEST CONDITION
Standard Test Condition: a)Temperature: +5~+35oC b)Humidity:45~85% c)Pressure: 860~1060mbar

solderability
Lead terminal are immersed in rosin for 5
seconds and then immersed in solder bath of
+260±5oC for 3±1 seconds.
90% min. lead terminals will be wet with solder
(except the edge of the terminal)
soldering heat resistance Lead terminal are immersed in soldering bath of No interference in operation.

strength
The force 10 seconds of 9.8N is applied to each No damage and cutting off.
terminal in axial direction.
vibration
Buzzer will be measured after being applied
vibration of amplitude of 1.5mm with 10Hz to
55Hz band of vibration frequency to each of 3
perpendicular directions for 2 hours
The value of oscillation frequency current
consumption would be in ±10% compared with
initial one.
drop test
The part only will be dropped from a height of The SPL would be in±10dB compared with initial
75cm onto a 40mm thick wooden board 3 times one
in 3 axes(X,Y,Z). A total of 9 times.
