Environment Test

Item

Test Condition

High temp. test

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

240 hours.

Low temp. test

After being placed in a chamber at -30°C for

240 hours.

Humidity test

After being placed in a chamber at +40°C and

90±5% relative humidity for 240 hours.

Temp. cycle test

The part should be subjected to 5 cycles. One

cycle will consist of:

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 within ±10dB compared to the

initial measurements.

Mechanical Characteristics

Item

Test Condition

Solderability

Lead terminals are immersed in rosin for

5 seconds and then immersed in solder bath

of 270 ±5°C for 3 ±1 seconds.

Soldering Heat Resistance

Lead terminals are immersed up to 1.5mm from

buzzer’s body in solder bath of 300 ±5°C for

3±0.5 seconds or 260 ±5°C for 10 ±1 seconds.

Terminal Mechanical Strength

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

applied to each terminal in axial direction.

Vibration

The buzzer should be measured after applying

a vibration amplitude of 1.5 mm with 10 to

55 Hz band of vibration frequency to each of

the 3 perpendicular directions for 2 hours.

Drop Test

The part will be dropped from a height of

75 cm onto a 40 mm thick wooden board 3

times in 3 axes (X, Y, Z) for a total of 9 drops.

Evaluation Standard

90% min. of the lead terminals

will be wet with solder. (Except

the edge of the terminal)

No interference in operation.

No damage or cutting off.

The value of oscillation

frequency/current consumption

should be ±10% of the initial

measurements. The SPL should

be within ±10dB compared with

the initial measurement.
