Home Appliance Safety Testing Services

Home appliances typically connect directly to the power grid, have high power consumption, and feature functions such as high-temperature heating and motor rotation. The users may include elderly, children, and other vulnerable groups, making safety requirements more critical than for other products. For electric heating products, both temperature control and fire prevention are crucial, while motor-driven products require special attention to insulation and mechanical injury risks.

Example of Toaster Safety Testing

- Temperature Rise Test: The appliance is operated under standard working conditions for 15 minutes, measuring the temperature at the knob, outer casing, power cord, and interior. The temperature must not exceed the specified limit.

- Fire Test: This simulates an abnormal situation. A slice of bread is placed in the toaster, preventing the mechanical ejector from activating, allowing the bread to burn until the flame extinguishes. After the test, the toaster’s touch protection and pressure resistance tests must meet the standard requirements.

Example of Coffee Maker Safety Testing

- Overflow Test: Simulates the situation where the container overflows when filled with water, followed by a pressure test. For example, a pressure of 3000V is applied between live parts and accessible metal surfaces for 1 minute as per en60335-1.

- Abnormal Test: The thermostat is short-circuited, and input power is increased based on the rated power to allow the heating element to continue heating, checking if the temperature protection device works. If the temperature rise meets the standard even without the protective device working, the product is considered qualified. After the test, a pressure resistance test is conducted.

Example of Stand and Table Fan Safety Testing

- Motor Locking Test: The motor is blocked, and under rated voltage, the motor continues to heat up. This test checks whether the temperature protection device functions. If the temperature rise complies with the standard even when the protective device does not activate, the product is deemed qualified.

- Oscillation Test: For fans with an oscillating function, a durability test is conducted by running the fan head rotation for 100,000 cycles.

Example of Oven Surface Temperature Rise Test

- Oven Surface Temperature Rise Test: Under normal operating conditions with rated power, the oven is operated until it stabilizes. The surface temperature rise is measured. The temperature rise limit is specified in the EN60335-2-9 Table Z101 requirements.

- Exemptions for some outer surface testing are detailed in the EN60335-2-9 Figure Z103.

EMF – Electromagnetic Field Radiation to Humans: This requirement assesses the strength of the magnetic field radiation produced by home appliances during normal use, ensuring that the appliance’s magnetic field radiation stays within safe reference levels for human safety. The test is conducted according to the EN62233 standard.

ErP – Risk Assessment for Home Appliances: For products with electronic controls that feature standby mode, it is necessary to test the product’s susceptibility to discharge interference in standby mode to check for potential risks or adverse effects.
