10.Reliability Test .
10.1. (High-Low Temp):
Place products into 70℃±5℃temperature test chamber in 8 hours, Then to have
products recover to normal temp in normal room temperature.
Place products into -20℃±5℃temperature test chamber in 8 hours, Then to have
products recover to normal temp in normal room temperature.
10.2. Drop test:
Drop to the concrete for all 6 faces freely, Height: 1m
Criterion: Housing won't be divided and be without crack during test or after test. And
all functions should work as before test.
10.3. Burn-In Test:
Normal temperature 25 ° ± 5 °, 5W aging 2H.
10.4. Salt Spray Test:
Salt Water Concentration:5%(9.5L water+500gNaCl)
Pressure/:1.0±0.1Kg/cm2;
Air Pail Temp:47±1℃;
Salt Water Pail:35±1℃;
Test Time: 24hours
Criterion: All metal parts surface are without rust, Bubble, Peeling off after test and
cleaning all water on surface
10.5.Connector Inserting and Removing:
Frequency: 8 Times/1minute
Micro USB : 2000times, Inserting force after test should be: F≤3.5KG; And
Removing force after test should be: 3.5kg≥ F ≥1kg
Criterion: Connector still works well and structure still look good after test. And
inserting and removing force after test is still in range.
