III. Reliability Tests
Vibration Test
The microphone to have no interferance in operation after vibrations, 10Hz to 55Hz for
1minute full amplitude 1.52mm, for 2 hours at three axises.
Drop Test The microphone unit must operate when dropped three times once on each axis from a
height of 1m onto a metal plate.
Temperature Test The microphone unit must operate within its sensitivity specifications after
subjected to the following conditions: +85°C for 240 hrs, and exposed to room
temperature for 2 hrs.
The microphone unit must operate within its sensitivity specifications after
subjected to the following conditions: -40°C for 240 hrs, and exposed to room
temperature for 2 hrs.
High
Low
Humidity Test +60°C at 95%RH for 200 hrs
Temperature Cycle Test After exposure at -40°C for 45 minutes, at +85°C for 45 minutes, 27 cycles. (The
measurements to be done after 2hrs of conditioning at +20°C)
After any of the following tests performed, the sensitivity of the microphone unit
shall not deviate more than ±3dB from its initial value. The microphone shall
maintain its initial operation and appearance. Measurements for tests with
thermal requirements are to be done after 2hrs of condistioning at 20°C.
