What is UL 719?

UL 719 is a standard established by Underwriters Laboratories (UL), an independent testing and certification organization. This standard specifically addresses the safety requirements for commercial electric oil heaters, including circulation heaters, convection air heaters, and panel heaters.

Key Safety Requirements

UL 719 sets forth several important safety requirements that a commercial electric oil heater must meet in order to receive UL certification. These requirements include:

Leakage Current Tests: The heater must undergo tests to ensure that there is no excessive leakage current, which could pose a shock hazard.

Temperature Limitations: The maximum temperature of the heater's surface must be within safe limits to prevent burns or other injuries.

Overheating Protection: The heater must have a built-in mechanism to prevent overheating, such as a thermal cutoff switch, to reduce the risk of fire or damage.

Stability and Mechanical Strength: The heater's construction and design must be sturdy and stable to prevent tipping over or other accidents.

Certification Process

To obtain UL 719 certification, manufacturers must submit their products to rigorous testing conducted by UL. The testing process includes inspections of the product's construction, materials, and overall performance according to the standard's requirements.

If a heater meets all the necessary safety requirements, it will be granted UL 719 certification. The certification mark can then be displayed on the product to indicate its compliance with the standard.

The Importance of UL 719

UL 719 plays a crucial role in ensuring the safety of commercial electric oil heaters. By adhering to the standard's requirements, manufacturers can demonstrate their commitment to producing reliable and safe products.

For consumers, the UL 719 certification mark serves as a trusted indicator that the heater has undergone thorough testing and meets the necessary safety standards. This helps them make informed decisions when choosing a commercial electric oil heater for their needs.
