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 solder bath of
260 ±5°C for 3 ±1 seconds.
Apply a force of 9.8 N (1.0 kg) to each terminal
in each axial direction.
The buzzer will be measured after applying
a vibration amplitude of 1.52 mm with 10 to
55 Hz band of vibration frequency to each of
the 3 perpendicular directions for 2 hours.
The part is to be dropped from a height of
75 cm onto a 40 mm thick wooden board 3
times in 3 axis (X, Y, Z) for a total of 9 drops.
Evaluation Standard
90% min. lead terminals should
be wet with solder.
(Except the edge of the terminal.)
Test Condition
The part will be subjected to +70°C for
96 hours.
The part will be subjected to -30°C for
96 hours
The part will be subjected to 10 cycles. One
cycle will consist of:
Evaluation Standard
No in interference in operation.
No damage or cutting off.
After the test, the part should
meet specifications without any
damage to the appearance and
the SPL should be within
±10 dBA of the initial
measurement.

After the test, the part should
meet specifications without any
damage to the appearance or
performance except SPL. After 4
hours at 25°C, the SPL should be
within ±10 dBA of the initial
measurement.

Reliability Tests
Item
Operating (Life Test)
Test Condition
1. Continuous life test:
The part will be subjected to 72 hours at 45°C
with 1.5 V, 2048 Hz applied.
Evaluation Standard
2. Intermittent life test:
A duty cycle of 1 minute on, 1 minute off, a
minimum of 10,000 times at room temp.
(+25 ±10°C) with 1.5 V, 2048 Hz applied.
After the test, the part shall meet
specifications without any
damage to the appearance. After
4 hours at +25°C, the SPL
should be within ±10 dBA of the
initial SPL.
