Environment Test
Item Test Condition
High temp. test After being placed in a chamber at +95°C for
240 hours.
Low temp. test After being placed in a chamber at -40°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 shall 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 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.
Terminal Mechanical Strength The pull force should be applied to the double
lead wire:
Horizontal 3.0N (0.306kg) for 30 seconds
Vertical 2.0N (0.204kg) for 30 seconds
Vibration The buzzer shall 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 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.
