Safety test

Test item

Test specification

Electrical strength test

Determine whether the internal insulation materials/components of the product, or the wiring arrangement, can still play a good insulation effect under high pressure conditions.

Exception test

Determine that the product can still be safe under the conditions of abnormal use or failure of some internal components (short circuit or open circuit).

Vibration test

Determine whether the equipment parts have come loose after the durability treatment of sweep vibration, endangering the safety of the parts or connections

Temperature rise test

Determine whether the temperature of the product meets the standard requirements under normal use and abnormal use conditions (such as blocked ventilation holes), and there is no risk of overheating, which will cause the risk of burning the product.

Ball pressure test

Determine whether thermoplastic parts used to support dangerous voltages in the product will soften under prolonged abnormal heat, leading to danger.

Adhesive aging test

Determine whether a baffle or screen in a product that relies on an adhesive to hold it in place will retain sufficient bonding properties over the life of the product. These baffle plates or partitions are intended to meet standard opening requirements or electrical insulation distance requirements.

Contact current test
(Leakage current test)

Determine whether the leakage current of the product from the AC power grid or communication network through certain lines to the user can contact the surface meets the requirements of the standard.

Mechanical strength test

In the process of use, the simulation product can accidentally withstand external forces (such as: the product does not fall on the hard ground, and an object falls/presses/collides with the product surface) can still effectively play a mechanical/electrical protection effect, and there will be no danger.

Power cable seat and tensile test

Determine whether the connection between the product and the power cord is reliable, mainly for the non-separated power cord.

Wall hanging test

The simulation product is mounted on the wall or ceiling to determine the reliability of its installation

Stability test
(10°Tilt test)

The simulated product is placed on an uneven interface, and the product does not flip over.

High temperature and humidity test

In the future, the simulation product will be in the harsh environment of high temperature and humidity, whether the internal circuit design and the materials used are reliable and will not occur insulation collapse.

Power limit test

Determine whether the power supply is a Limited power source, which is used to determine whether the powered part or product can be powered without a fireproof housing.

Operating voltage test

Test the working voltage difference between the primary side and the secondary side when the product is working normally, record the peak (Vpeak) and Vrms voltage. The RMS voltage is used to determine the creepage distance and the peak voltage is used to determine the clearance distance.

Impedance to protect the ground

To verify that the connection mode used to connect the protective ground in the product is sufficient to pass high current without disconnection and hazard.

Capacitance discharge test

It is determined that when the product is powered off, the energy storage characteristics of the capacitor should be considered, and there is still a danger between the power input L/N

Current limiting circuit test

Determine whether some lines are current-limiting circuits. Current-limiting circuits are ones that the human body can touch directly.

SLEV Reliability test

Determine whether some lines are SELV lines, SELV lines are directly touched by the human body.

Label durability test

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