What is UL 60335-2-109?

UL 60335-2-109 is a technical standard developed by Underwriters Laboratories (UL) for household and similar electrical appliances. It specifies safety requirements for appliances that operate with voltages up to 250 volts. This standard covers a wide range of appliances including cooking appliances, refrigerators, washing machines, dishwashers, and many others.

Importance of UL 60335-2-109

Ensuring the safety of electrical appliances is crucial to protect consumers from potential hazards. UL 60335-2-109 provides a framework to evaluate and test appliances, reducing the risk of fires, electric shocks, and other accidents. Compliance with this standard gives consumers confidence that the appliance they are using has undergone rigorous safety evaluations.

Key Requirements of UL 60335-2-109

UL 60335-2-109 covers various aspects of appliance safety, including insulation, grounding, mechanical strength, temperature limits, and protection against moisture and dust. Manufacturers must ensure that their appliances meet these requirements before they can be certified as compliant. The standard also addresses potential risks associated with faulty installation, misuse, or external influences.

The Certification Process

To obtain UL 60335-2-109 certification, manufacturers submit their appliances to a thorough evaluation process conducted by independent laboratories recognized by UL. These tests may include high voltage and current tests, endurance tests, abnormal operation tests, and environmental tests to simulate real-life conditions. Once an appliance successfully passes all required tests, it receives the UL mark, indicating its compliance with the standard.
