ꢁONTINUOUS LIFE TEST
After the test the part will meet specifications
48hours of continuous operation at +55ꢀꢁ with without any degradation in appearance and
maximum rated voltage applied.
INTEꢂMITTENT LIFE TEST
A duty cycle of 1 minute on, 1 minutes off, a
minimum of 1000 times at +25 2ꢀꢁ and
maximum rated voltage applied
performance except SPL, after 4 hours at +25ꢀꢁ.
The SPL would be in 10dBA compared with
initial one.
TEST CONDITION
Standard Test ꢁondition: a)Temperature: +5~+35ꢀꢁ b)Humidity:45~85ꢃ c)Pressure: 860~1060mbar

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 10ꢃ 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.
