Performance Requirements
5-1.
Vibration
Buzzer shall be measured after being
applied vibration of amplitude of 1.5
mm
with 10 to 55 Hz band of vibration
frequency to each three mutually
perpendicular directions for 2 hours.
The measured values
meet Table 1.
5-2.
Resistance to
Soldering Heat
Lead terminal are immersed up to 1.5
mm
from Buzzer’s body in solder bath of
300
± 5°C for 3 ± 0.5 seconds or 260 ±
5°C for
10 ± 1 seconds, and then sounder
shall be
measured after being placed in natural
condition for 4 hours.
The measured values
meet Table 1.

High
Temperature
After being placed in a chamber with +85
± 2°C for 240 hours and then being placed
in natural condition for 4 hours, Buzzer
shall be measured.
The measured values
shall meet Table 1.
6-2.
Low
Temperature
After being placed in a chamber with -40
± 2°C for 240 hours and then being placed
in natural condition for 4 hours, Buzzer
shall be measured.
6-3.
Humidity
After being placed in a chamber with 90
to 95% R.H. at + 40 ± 2°C for 240 hours
and then being placed in natural
condition for 4 hours, Buzzer shall be
measured.
6-4.
Temperature
Cycle
After being placed in a chamber at -40 ±
2°C for 30 minutes, Buzzer shall be placed
at room temperature (+20°C). After 15
minutes at this temperature, buzzer shall
be placed in a chamber at +85 ± 2°C.
After 30 minutes at this temperature,
buzzer shall be returned to room
temperature (+20°C) for 15 minutes.
After 5 above cycles, buzzer shall
measure after being placed in natural
condition for hours.
