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.

RELIABILITY TEST
item test condition
operating (life test) 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 minutes 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.
TEST CONDITIONS
standard test condition a) tempurature: +5 ~ +35°C b) humidity: 45 - 85% c) pressure: 860-1060 mbar
judgement test condition a) tempurature: +25 ±2°C b) humidity: 60 - 70% c) pressure: 860-1060 mbar
