What is UL60335-2-21?

UL60335-2-21 is a technical standard that applies to safety requirements for household and similar electrical appliances. It has been developed by Underwriters Laboratories (UL), an independent testing and certification organization based in the United States, with the aim of ensuring the safety and reliability of these appliances.

Safety Requirements

The UL60335-2-21 standard specifies various safety requirements that electrical appliances need to meet in order to be considered safe for consumer use. These requirements include insulation resistance, electrical connections, temperature limits, protection against electric shocks, and safeguards against overheating or ignition. The standard covers a wide range of appliances such as refrigerators, washing machines, dishwashers, and ovens.

Testing and Certification Process

To comply with the UL60335-2-21 standard, manufacturers need to subject their appliances to rigorous testing and evaluation. This is done by accredited laboratories that are recognized by UL. The testing process includes checking for compliance with the standard's specific requirements, conducting performance and reliability tests, and evaluating the appliance's overall safety features. Once an appliance successfully passes all the tests, it can be certified as compliant with the UL60335-2-21 standard.

Benefits and Importance

Compliance with the UL60335-2-21 standard is crucial for manufacturers as it ensures the safety of their products and builds trust among consumers. Appliances that are certified to meet this standard carry the UL mark, indicating that they have undergone extensive testing and meet strict safety requirements. For consumers, purchasing appliances with the UL mark provides peace of mind knowing that they are purchasing products that have been independently tested and verified for safety.

In conclusion, the UL60335-2-21 standard plays a crucial role in ensuring the safety and reliability of household electrical appliances. Manufacturers who comply with this standard demonstrate their commitment to producing safe products, while consumers benefit from appliances that have undergone rigorous testing and meet strict safety requirements.
