What is UL60335-2-79? -


UL60335-2-79 is a safety standard that specifically applies to electrical household and similar appliances that have heating elements. This standard ensures that these appliances meet certain safety requirements before they can be sold in the market.

Scope of UL60335-2-79

UL60335-2-79 covers a wide range of appliances, including ovens, toasters, electric heaters, hairdryers, and many others. It focuses on the safety aspects of these appliances, ensuring that consumers are protected from potential hazards such as electric shock, fire, and burns.

The standard defines various tests and requirements that manufacturers need to comply with in order to obtain the UL certification for their products. These requirements encompass factors like construction, temperature limits, insulation, wiring, and grounding among others.

Key Requirements of UL60335-2-79

One of the main requirements of UL60335-2-79 is the verification of proper grounding. Appliances must be designed and constructed in a way that reduces the risk of electric shock for the users. This is achieved by ensuring that appropriate grounding measures are implemented, preventing any leakage of current to the external metal parts of the appliance.

The standard also sets limits on the surface temperatures of heating elements, protecting users from burns. Appliances should not exceed specified temperature limits during normal operation and under certain fault conditions.

Additionally, UL60335-2-79 mandates that appliances be equipped with proper insulation to prevent short circuits or contact between live parts and accessible conductive surfaces. This minimizes the risk of electric shock and potential fire hazards.


UL60335-2-79 plays a critical role in ensuring the safety of electrical household and similar appliances. By complying with this standard, manufacturers can provide consumers with products that meet stringent safety requirements, protecting them from potential hazards. Understanding the scope and key requirements of UL60335-2-79 allows consumers to make informed decisions when purchasing electrical appliances for their homes.
