PRODUCT SPECIFICATION Doc: MB6052ASC-1 III. Reliability Tests Vibration Test The microphone to have no interferance in operation after vibrations, 10Hz to 55Hz for 1 minute 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: +70°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: -25°C for 240 hrs, and exposed to room temperature for 2 hrs. High Low Humidity Test +40°C at 95%RH for 240 hrs Temperature Cycle Test After exposure at -55°C for 30 minutes, at+20°C for 10 minutes, at +85°C for 30 minutes, at +20°C for 10 minutes, 5 cycles. (The measurement to be done after 2 hrs 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. Note: IV.
