Rated Input Power: The input power specified by the appliances' manufacturer. The input power test is one of the common safety performance tests of electronic and electrical products as it is used to evaluate whether the labels are accurate and whether there are dangers of over temperature when the product is used for long periods of time; this prevents the risk of fires from heat released by products during operation.

The residual voltage is the voltage between the poles of the power plug and the energy inside energy storing components inside electrical equipment that remains for a period of time after electrical equipment are powered off. The residual voltage test is one of the important safety performance tests of electronic and electrical products as it is directly related to the personal safety of normal users during operation. This is especially true in regard to the safety of household appliances, which can affect the lives and property of thousands of households.

The connection resistance between the accessible metal parts of the electrical appliance and the grounding terminal or grounding contact. The ground resistance test is one of the important safety performance tests of electronic and electrical products, used to quantitatively evaluate the grounding continuity of electrical appliances, with the resistance value indicating the reliability of the grounding capability. A grounding resistance that is too large may still cause harm to the human body, otherwise, it functions as protection.

Dielectric Withstand Voltage Test: A test to determine whether the insulation material and the spacing meets compliance requirements by applying a voltage higher than a device's rated value for a period of time. The dielectric withstand voltage test is one of the important safety performance tests of electronic and electrical products, used to evaluate the quality and electrical safety characteristics of the equipment.

Leakage Current: The electric current formed, under no external pressure or equipment malfunction, by the surrounding dielectric between insulated electrical parts, ground parts and metals.  The leakage current test is one of the important safety performance tests of electronic and electrical products, used to evaluate the safety characteristics the equipment. The existence of leakage current deprives the safety performance of electronic products and pose as potential safety hazards for users.

Stability: Under normal usage conditions, the instability caused by the equipment's components and structure must not reach levels that will put users or maintenance personnel in danger. The stability test is one of the common safety performance tests of electronic and electrical products, used to evaluate the dangers of an electrical machinery; if stability is not in compliance, harm to the human body may be caused.

Equipment should possess enough mechanical strength and their structure should guarantee no danger will come when subject to expected operations. The shell mechanical strength test is one of the common safety performance tests of electronic and electrical products, used to evaluate the dangers of the electrical machinery; if the shell mechanical strength is not of compliance, it may cause mechanical and electric shock injuries to the human body.

During normal operation, the temperature of the devices’ components cannot be too high. Some components experience heating from high levels of current, resulting in their temperatures to rise too high. And working under these conditions for long periods of time may reduce the performance of the insulating material, which in turn cause the equipment to risk being electric shocked, burning or catching fire. The temperature test is one of the important safety performance tests of electronic and electrical products, used to evaluate the quality and electrical safety characteristics the equipment.
