Water-resistant and dust-resistant level denition
and usage scenario description of wearable devices
Being water-resistant and dust-resistant means that the wearable device prevents water and
dust from entering inside and damaging the interior components and the mainboard.
In the following test scenarios, the normal temperature ranges from 15°C to 35°C, the
relative humidity ranges from 25% to 75%, and the atmospheric pressure ranges from 86
kPa to 106 kPa (the standard atmospheric pressure is 101.325 kPa).
