Title: Understanding UL 856: The Safety Standard for Electrical Heated Blankets

When it comes to home safety, one of the most crucial aspects is the use of electrically heated blankets. These blankets have become a staple in modern homes, providing warmth and comfort to those who need it. However, with the increasing popularity of these products, there is a growing concern about their safety. to ensure the safety of electrically heated blankets, Underwriters Laboratories (UL) has developed UL 856, a widely recognized standard for safety requirements in the electrical industry.

What is UL 856?

UL 856 is a safety standard that sets forth rigorous testing procedures and performance requirements for electrically heated blankets. It is designed to minimize the risks associated with the use of these products and prevent potential hazards such as overheating, electrical shocks, or fire outbreaks.

Key Requirements of UL 856

UL 856 has several key requirements that manufacturers must adhere to in order to obtain UL certification for their products. These requirements include:

Electrical Safety: The blanket must be designed and manufactured to minimize the risk of electrical shock. This includes ensuring that all electrical components are properly insulated and that the blanket itself is resistant to electrical currents.

Fire Resistance: The blanket must be able to withstand a fire for a specified amount of time without igniting or catching fire.

Temperature Limits: The blanket must not exceed a specified temperature for a specified amount of time without showing signs of overheating or catching fire.

Safety Harness: The blanket must be designed with a safety harness that is easily accessible and can be quickly and easily fastened or tightened in case of an emergency.

Test procedure: The manufacturer must follow a specific testing procedure to ensure that their product meets the requirements of UL 856.

Conclusion

UL 856 is an essential safety standard for electrically heated blankets. It ensures that manufacturers produce products that are safe for use and minimize the risks associated with their use. By following the guidelines and requirements set forth by UL 856, manufacturers can provide their customers with safe and reliable products that they can rely on.
