Mobile Phone Charge Test Standard

Charge test is really important for mobile phones, especiall for OEM mobile phones. To ensure the mobile phone charge work naturally, all the Chinese OEM moible phone manufacturers will test and inspect the OEM mobile phones' charge quality first before shipment. Generally, the OEM mobile phone tests are based on these standards in the below list:

2PCS


No breakdown and arc.

 

5


Resistance of insulation

 


3750V 50Hz alternating voltage for 1min, Inspect between the parts with eletricity and output circuit, between the parts with eletricity and shell, whether occurred the breakdown and arc.

2PCS


No breakdown and arc. Insulation resistance is more than 7MΩ.

 

6

Over voltage protection

 

Short or open any circuit in the sub-layer, Inspect the Zener diode whether reverse breakdown, output voltage of charger is zero, then cut off the Zener diode, inspect the output voltage whether return or not.
