What is UL 60335-2-45?

UL 60335-2-45 is a technical standard developed by Underwriters Laboratories (UL) to ensure the safety and reliability of household and similar electrical appliances. It specifically focuses on the safety requirements for portable heating tools, such as hair dryers, curling irons, and flat irons. This standard sets the guidelines that manufacturers must adhere to in order to comply with safety regulations and provide consumers with safe and reliable products.

Key Requirements of UL 60335-2-45

UL 60335-2-45 specifies various safety requirements that manufacturers need to meet. One important requirement is the prevention of electrical shock hazards. Appliances must be designed and constructed in a way that minimizes the risk of electric shocks, even under abnormal conditions such as water exposure or insulation failures.

Another key requirement is thermal protection. Appliances should incorporate mechanisms that prevent overheating, thus avoiding potential fire hazards. Tests are conducted to ensure that devices shut off automatically when the temperature exceeds a certain limit.

In addition, UL 60335-2-45 covers mechanical and structural requirements. Appliances should be built with materials that are resistant to heat and mechanical stress. The standard also addresses issues such as cord anchorage, strain relief, and the strength of handles and switches.

The Importance of UL 60335-2-45 Compliance

Complying with UL 60335-2-45 is essential for manufacturers to demonstrate that their products are safe for consumer use. Obtaining UL certification provides confidence to both manufacturers and consumers that the appliance has undergone rigorous testing and meets stringent safety standards.

By adhering to this standard, manufacturers can minimize the risks associated with their products, such as electrical malfunctions, fires, and injuries to users. It also helps them avoid legal issues, as non-compliance can result in recalls, fines, or lawsuits.

For consumers, buying appliances that comply with UL 60335-2-45 ensures peace of mind and protection. They can trust that the products they use daily have been thoroughly evaluated for safety, reducing the likelihood of accidents and ensuring a high level of product performance.


UL 60335-2-45 plays a crucial role in ensuring that portable heating tools meet strict safety requirements. By complying with this standard, manufacturers are able to demonstrate their commitment to producing safe and reliable appliances. Consumers benefit from purchasing certified products, as they can be confident in the quality and safety of their household electrical appliances.

As technology continues to advance, it is essential for standards like UL 60335-2-45 to evolve and adapt to new safety challenges. This ongoing development aims to provide even greater protection for consumers and promote innovation in the household appliance industry.
