a) The test method is performed based on the related definitions in GB/T 2423.3. b) Conditional test. Test sample is put into the chamber based on the normal state. It is installed with the matched battery with power-off. Power on and increase the humidity chamber to 40??C. Then wet it and mix the air in the chamber. When the temperature reaches to the required one and the relative humidity is 90%???95%, keep it for 48h.
c) After the conditional test, detect RF performance finally.
4.1.8 Salt frog test methods
a) The test method is performed based on the related definitions in GB/T 2423.18. b) Conditional test. Place the unpacked test sample without the matched battery in salt frog chamber, and spray the frog for 2 hours in (15???35)??C, the pH value is within 6.5~7.2(when the temperature is 20??C??2??C), and the density of sodium chloride solution is (50??1)%. After the completion of frog spraying, move the test sampl...
