Title: What is UL 852 and UL 859? A Guide to Electrical Safety Standards

When it comes to the safety of our products, we all want the best. This is especially true when it comes to electric dryers, which can be a hazardous appliance if not handled properly. To ensure the safety of these products, Underwriters Laboratories (UL) offers certifications and evaluations. One of the important safety standards for electric dryers is UL 852, which outlines the minimum safety requirements that must be met by electric dryers to prevent hazards such as electrical shock, fire, or mechanical failure.

UL 852: The Safety Requirements for Electric Dryers

UL 852 is a standard developed by UL to ensure the safety of electric dryers. The standard covers various aspects of the dryer, including its electrical components, construction, performance, and instructions for safe operation. The key areas covered by UL 852 include:

* Electrical Components: The standard outlines the types of electrical components that must be used in electric dryers, such as transformers, motors, and control panels. These components must be designed to prevent electrical hazards, such as electrical fires or shocks.

* Construction: The standard specifies the materials that can be used in the construction of electric dryers, such as the shell, enclosure, and internal components. These materials must be fire-resistant and made of non-toxic materials that are safe for use with electrical equipment.

* Performance: The standard outlines the performance requirements for electric dryers, such as maximum temperature rise, current draw, and power consumption. These requirements are designed to ensure that the dryers are safe to use and do not pose a hazard to users or those around them.

* Instructions for Safe Operation: The standard specifies the instructions that must be provided with electric dryers, including how to properly plug in the dryer, how to turn it on and off, and how to use it safely. These instructions must be clear and concise, and they must include all necessary safety precautions.

UL 859: The Safety Requirements for Electrically Heated Blankets

UL 859 is another important standard developed by UL to ensure the safety of electrically heated blankets. The standard focuses on the safety requirements for electrically heated blankets, which are used in various applications, such as hospitals, nursing homes, and hotels. The purpose of this standard is to minimize the risks associated with the use of electrically heated blankets and prevent potential hazards such as overheating, electrical shocks, or fire outbreaks.

Key Requirements of UL 859

UL 859 sets forth rigorous testing procedures and performance requirements that manufacturers must adhere to in order to obtain UL certification for their products. The key requirements of UL 859 include:

* Electrical Safety: The standard outlines the electrical safety requirements for electrically heated blankets, including the use of non-incorrect materials, the presence of proper labeling, and the use of electrical isolation devices.

* Fire Safety: The standard specifies the fire safety requirements for electrically heated blankets, including the use of fire-resistant materials, the presence of fire-resistant coatings, and the use of heat-resistant fasteners.

* Performance: The standard outlines the performance requirements for electrically heated blankets, including the maximum temperature rise, current draw, and power consumption.

* Safety Test: The standard specifies the testing procedures that manufacturers must follow to ensure that their products meet the requirements of the standard. These tests include electrical safety tests, fire safety tests, and performance tests.

Conclusion

UL 852 and UL 859 are important safety standards for electric dryers and electrically heated blankets, respectively. These standards ensure that the products are safe to use, meet the necessary safety requirements, and are labeled properly. By following the guidelines outlined in these standards, manufacturers can provide their products with the necessary safety features and minimize the risks associated with their use.
