Measurement Method

Mechanical Characteristics

Item

Test Condition

Solderability

Stripped wires of lead wires are immersed in

(Connector Excepted)

rosin for 5 seconds and then immersed in

a solder bath of +270 ±5°C for 3 ±0.5 seconds.

Lead Wire Pull Strength

The pull force should be applied to double lead

wire:

Horizontal 3.0N (0.306kg) for 30 seconds

Vertical 2.0N (0.204kg) for 30 seconds

Vibration

The buzzer will 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 axis (X, Y, Z) for a total of 9 drops.

Evaluation Standard

90% min. of the stripped wires

will be wet with solder.

(Except the edge of the terminal)

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.
