test condition
Lead terminals are immersed in rosin for
5 seconds and then immersed in solder bath
of 270 ±5°C for 3 ±1 seconds.
Lead terminals are immersed up to 1.5 mm
from the buzzer’s body in a solder bath of
300 ±5°C for 3 ±0.5 seconds or 260 ±5°C for
10 ±1 seconds.
The force of 9.8 N (1 kg) will be applied for
10 seconds to each terminal in each axial
direction.
The buzzer shall be measured after applying
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.
The part will be dropped from a height of
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).
test condition
After being placed in a chamber at +95°C for
240 hours.
After being placed in a chamber at -40°C for
240 hours.
After being placed in a chamber at +40°C and
90±5% relative humidity for 240 hours.
The part shall be subjected to 5 cycles. One
cycle will consist of:
evaluation standard
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.
1. Not recommended for wave soldering
ENVIRONMENT TEST
item
high temp. test
low temp. test
humidity test
temp. cycle test
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.

RELIABILITY TEST
item
operating (life test)
test condition
1. Continuous life test:
The part will be subjected to 48 hours of
continuous operation at +70°C with rated
voltage applied.
2. Intermittent life test:
A duty cycle of 1 minute on, 1 minute off, a
minimum of 5,000 times at room temp
(+25 ±2°C) with rated voltage applied.
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.
