90±5% relative humidity for 240 hours.
Temp. cycle test The part shall be subjected to 5 cycles. One
cycle will consist of:
Evaluation Standard
The buzzer will be measured after
being placed at +25°C for 4
hours. The value of the
oscillation frequency/current
consumption should be ±10%
compared to the initial
measurements. The SPL should
be within ±10dB compared to the
initial measurements.

5 seconds and then immersed in solder bath
of 270 ±5°C for 3 ±1 seconds.
Soldering Heat Resistance Lead terminals are immersed up to 1.5mm from
buzzer’s body in solder bath of 300 ±5°C for
3 ±0.5 or 260 ±5°C for 10 ±1 seconds.
Terminal Mechanical Strength For 10 seconds, the force of 9.8N (1.0kg) is
applied to each terminal in axial direction.

a vibration amplitude of 1.5 mm with 10 to
55 Hz band of vibration frequency to each of
the 3 perpendicular directions for 2 hours.

75 cm onto a 40 mm thick wooden board 3
times in 3 axes (X, Y, Z) for a total of 9 drops.
Evaluation Standard
90% min. of the lead terminals
will be wet with solder. (Except
the edge of the terminal)
No interference in operation.
No damage or cutting off.
The value of oscillation
frequency/current consumption
should be ±10% of the initial
measurements. The SPL should
be within ±10dB compared with
the initial measurement.
