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 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
