1. Ordinary temperature:

The part will be subjected to 100 hours at room temperature (25°C

±10°C) with 3 V, 4,000 Hz applied.

2. High temperature:

The part will be subjected to 50 hours of continuous operation at

55°C with 3 V, 4,000 Hz applied.

2. Low temperature:

The part will be subjected to 50 hours of continuous operation at

-30°C with 3 V, 4,000 Hz applied.

After any tests, the buzzer will meet

specifications without any damage in

appearance except SPL. After

4 hours at 25°C, SPL should be within

±10 dBA of the initial measurements.
