Evaluation Standard
Test Condition
1. Continuous life test:
The part will be subjected to 48 hours of
continuous operation at +70°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 ±10dB compared to the initial
measurements.
The buzzer will be measured after
being placed at +25°C for 4

oscillation frequency/current
consumption should be within
±10% compared to the initial
measurements. The SPL should
be within ±10dB compared to the
initial measurements.
