Ascending time up to 200°C should be longer than 30 seconds. Heating conditions should be within 10 seconds at 230°C min. Peak temperature should be 235°C. Then, place leave the buzzer in natural conditions for 1 hour before measuring. No interference in operation. 2) Soldering Iron Soldering iron of 270 ±5°C should be placed 0.5mm above the buzzer’s electrode. Melting solder through the soldering iron should be applied to the electrode for 3±1 seconds. Then, place the buzzer in natural conditions for 4 hours before measuring. No damage or cutting off. For 10 seconds, the force of 9.8N (1.0kg) is applied to each terminal in axial direction. The value of oscillation The buzzer shall be measured after applying frequency/current consumption a vibration amplitude of 1.55 mm with 10 to 55 Hz band of vibration frequency for 1 minute should be ±10% of the initial measurements. The SPL should to each of the 3 perpendicular directions for be within ±10dB compared with 2 hours. the initial measurement.
