Now, mobile phone is indispensable everyday communication tools, information technology, high-tech, multi-element development today, the phone's more powerful, therefore, humans rely on her degree relative increase the number. Accordance with relevant standards shows that the electronic communication devices adapt to the natural environment have become more sophisticated , of course, with unpredictable effects on the climate , the industry is also relatively resistant to external interference and require that the phone features impact also increased , therefore, to explain the phone damp heat test , aimed at mobile phones are not only meet the needs of human life , but in terms of quality , it enables the phone to endure the adverse environmental impacts grade endure heat performance test.
Testing Machine:
BA-TH80 constant temperature and humidity testing machine
Test procedure:
1.First wet cloth placed in the experimental apparatus humidity sensors to detect when the humidity test status
2.Sample preparation : take phone three sets , the specimen is placed in the test required before static temperature 23 ℃, relative humidity of 60 percent of the state, more than 12 hours pretreatment
3.Set experimental conditions : experimental temperature 40 ± 1 ℃, relative humidity of 93 ± 3%
4.placed in the sample the phone tester sample holder , and then set up an experiment temperature of 40 ℃; relative humidity of 93% under the conditions and begin heated humidification
5.When the test chamber temperature and humidity reaches the set value, the starting calculation time. N hours after the specimen was removed from the chamber and immediately check the appearance
6.Place the removed specimen placed for temperature 23 ± 2 ℃, relative humidity of 60 ± 5% of the state, to restore more than 6 hours , and then , into the shape of the power and performance checks phone
7.test continuity FM mobile radio telephone and ancillary equipment , after wet heat resistance test, its function is normal, and make report
Tips:
1.test time requirements for visual changes, such as : 4 hrs, 8 hrs, 16 hrs, 48 ??hrs, 72 hrs or 7 days, 14 days, 21 days, 28 days
2.During the test , the test can not arbitrarily open the door , so as not to affect the results
