MECHANICAL CHARACTERISTICS

item

test condition

evaluation standard

soldering

Lead terminals are immersed in a solder bath of +260 ±5°C for 3

±1 seconds.

95% min. of the lead terminals will be

wet with solder.

(except the edge of the terminal)

soldering heat resistance

The buzzer will follow the reflow temperature curve to test its

reflow thermo stability.

No interference in operation.

terminal mechanical strength

For 10 seconds, the force of 9.8 N (1.0 kg) is applied to each

terminal in each axial direction.

No damage or cutting off

vibration test

The buzzer should be measured after a vibration amplitude of 1.5

mm with 10 ~ 55 Hz band of vibration frequency to each of the

3 perpendicular directions for 6 hours.

After any tests, the buzzer will meet

specifications without any damage

in appearance and the SPL should be

within ±10 dBA of the initial

measurements.

drop test

The buzzer without packaging is subjected to 3 drops on each

axis from the height of 75 cm onto a 40 mm thick wooden board.

ENVIRONMENT TEST

item

test condition

evaluation standard

high temperature test

After being placed in a chamber at +80°C for 48 hours.

After any tests, the buzzer will meet

specifications without any damage in

appearance except SPL. After

4 hours at 25°C, SPL should be within

±10 dBA of the initial measurements.

low temperature test

After being placed in a chamber at -40°C for 48 hours.

thermal shock test

The part will be subjected to 10 cycles. One cycle will consist of:
