What is UL 197 ?

UL 197 is a widely recognized standard in the technical field that pertains to the safety of electric ranges and ovens. This standard is established by Underwriters Laboratories (UL) and is designed to ensure that these appliances operate safely and reliably, minimizing potential risks such as electrical hazards and fire outbreaks.

What is UL 197?

UL 197 is a technical standard that establishes safety requirements for electric ranges and cooking appliances. It is designed to prevent hazards and ensure that these appliances meet specific performance standards. Compliance with UL 197 demonstrates that manufacturers have followed stringent guidelines to create products that meet specific safety standards.

Key Components of UL 197

UL 197 is made up of several key components, including:

Electrical Construction: This component outlines the electrical requirements for the appliance, including the use of grounded, listed components and the requirement for listed wiring.

Mechanical Structure: This component outlines the mechanical requirements for the appliance, including the use of durable materials and the requirement for proper ventilation.

Heating Elements: This component outlines the requirements for the heating elements, including the use of heat-resistant materials and the requirement for thermal limits.

Temperature Controls: This component outlines the requirements for temperature controls, including the use of low-power thermal switches and the requirement for temperature limits.

Other Critical Components: This component outlines the requirements for other critical components, including the use of flame-resistant materials and the requirement for fire-resistant covers.

Key Requirements of UL 197

To ensure compliance with UL 197, manufacturers must follow these key requirements:

Electrical Construction: The electrical construction of the appliance must be designed to prevent electrical hazards, including the use of grounded, listed components and the requirement for listed wiring.

Mechanical Structure: The mechanical structure of the appliance must be designed to withstand the loads and stresses, including the use of durable materials and the requirement for proper ventilation.

Heating Elements: The heating elements of the appliance must be designed to provide uniform heat across the cooking surface, including the use of heat-resistant materials and the requirement for thermal limits.

Temperature Controls: The temperature controls of the appliance must be designed to allow for temperature limits and the requirement for low-power thermal switches.

Other Critical Components: The other critical components of the appliance, including the flame-resistant materials and fire-resistant covers, must be designed to prevent fire outbreaks and minimize the risk of electrical hazards.

Conclusion

UL 197 is an important technical standard that establishes safety requirements for electric ranges and cooking appliances. Compliance with this standard is essential to ensure that these appliances are safe to use and provide reliable performance. By following the key requirements outlined in UL 197, manufacturers can create products that meet specific performance standards and prevent hazards to users.
