Electronic Equipment Safety Testing

Test items 

Test instruction 

Pressure test

Determine whether the internal insulation   material or components of the product will break down under high voltage   conditions. If it does not break down, it passes, and if it does break down,   it fails.
   

Abnormal testing 

Determine whether the product can be used   without safety hazards when it is not in normal use (short circuit or open   circuit). 

Vibration Testing 

Determine whether the product parts are   loose after the sweep frequency vibration durability treatment, which may   endanger the safety of the parts. 

Temperature rise test 

Determine whether the temperature of the   product meets the standard requirements under normal and abnormal use, and   whether there is no danger of overheating or product combustion. 

Ball pressure test 

Determine whether the plastic material of   the product is hard and whether it will soften and cause danger if exposed to   abnormal heat for a long time. 

Glow Wire Test 

Determine whether the non-metallic parts   of the product are resistant to ignition and the spread of heat.
   

Leakage current test 

Determine whether the leakage current of   the product coupled from the AC power supply or certain lines to the surface   that the user can touch meets the standard requirements. 

Mechanical strength test 

When the product is in use, it can still   effectively provide mechanical/electrical protection when suddenly subjected   to external forces, and will not cause any danger.

Power cord fixing seat and tensile   test 

Determine whether the connection between   the product and the power cord is firm, mainly for non-detachable power   cords. 

Torque test

The external lead of the test product is   often bent and deformed by external forces during use. The wire can withstand   the bending times to determine whether it will break due to external forces   during the product life cycle.

Stability test
   

During normal use, the product is   subjected to various external forces. For example, if you lean on it or climb   on it during maintenance, it may cause dangers such as collapse or   overturning of the equipment.

High temperature and humidity test 

The test product may be used in harsh   environments of high temperature and high humidity in the future to determine   whether the internal circuit design and materials are reliable and whether   insulation collapse will occur. 

Power Limitation Test 

Determine whether the power supply   terminal meets the requirements of limited power supply, and determine   whether the powered components or products can be used without fireproof   enclosures. 

Working voltage test 

When the product is working normally, the   operating voltage difference between the primary side and the secondary side   is tested, and the peak (Vpeak) and effective value (Vrms) voltages are   recorded. The effective value voltage is used to determine the creepage   distance, and the peak voltage is used to determine the clearance   distance. 

Protective earth impedance 

To verify whether the connection method   used to connect the protective ground in the product is sufficient to pass   large current without disconnection and danger. 

Capacitor discharge test

When the power plug is unplugged, it is   charged, but this electricity disappears over time. If this time is too long,   it will cause electric shock to the person playing with the plug.
   

Current Limiting Circuit Test 

Determine whether some circuits are   current-limiting circuits, which can be directly touched by the human   body. 

Drop test
   

Small devices or desktop devices may fall   from your hands or workbench to the ground during normal use. These falls may   cause the internal safety indicators of the device to fail to meet the   requirements. 

Label durability test 

In order to test whether the   label screen printing on the product has a certain   durability.
