Lead terminals are immersed up to 1.5 mm from the buzzer’s body in solder bath of 260 ±5°C for 3 ±1 seconds. Apply a force of 9.8 N (1.0 kg) to each terminal in each axial direction. The buzzer will be measured after applying a vibration amplitude of 1.52 mm with 10 to 55 Hz band of vibration frequency to each of the 3 perpendicular directions for 2 hours. The part is to be dropped from a height of 75 cm onto a 40 mm thick wooden board 3 times in 3 axis (X, Y, Z) for a total of 9 drops. Evaluation Standard 90% min. lead terminals should be wet with solder. (Except the edge of the terminal.) No in interference in operation. No damage or cutting off. After the test, the part should meet specifications without any damage to the appearance and the SPL should be within ±10 dBA of the initial measurement. Soldering Heat Resistance Terminal Mechanical Strength Vibration Drop Test Environment Test Item High temp. test Low temp. test Thermal shock Test Condition The part will be subjected to +70°C for 96 hours.
