After being placed in a chamber at -30°C for 240 hours. After being placed in a chamber at +40°C and 90±5% relative humidity for 240 hours. The part shall be subjected to 5 cycles. One cycle will consist of: Evaluation Standard Test Condition 1. Continuous life test: The part will be subjected to 48 hours of continuous operation at +45°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 hours. The value of the oscillation frequency/current consumption should be within ±10% compared to the initial measurements. The SPL should be within ±10dB compared to the initial measurements. Reliability Test Item Operating (Life Test) 2.
