Vibration
Resist
The device
should satisfy the electrical characteristics
specified above after vibration is applied to
the antenna with vibration of 10 to 55Hz and
amplitude of 1.5mm for 2 hours each in X , Y and
Z directions.
Drop Shock
The device
should satisfy the electrical characteristics
specified above after dropping onto the hard
wooden board from the height of 30cm for 3 times
each facet of the 3 dimensions of the device.
High
Temperature Endurance
The device
should satisfy the electrical characteristics
specified above after exposed to a
temperature of 80 ± 5℃
for 24±2 hours and 1~2 hours recovery
time under normal temperature.
Low
Temperature Endurance
The device
should also satisfy the electrical
characteristics specified above after exposed to
the temperature -40℃
± 5℃
for 24±2 hours and to 2 hours recovery
time under normal temperature.
Temperature Cycle Test
The device
should also satisfy the electrical
characteristics specified above after exposed to
the low temperature -25℃
and high
temperature +85℃
for 30 ± 2 min each by 5 cycles and 1 to 2
hours recovery time under normal temperature.
Weatherproof
The antenna is placed
in 1m deep water for 12h, and
must be 100% waterproof. |
