At Tempco, we know that safety and reliability are key when designing and building heating products. That’s why top third-party agencies have tested and approved most of the products you’ll find on our website. These certifications make sure our products meet safety standards for heating elements. This helps engineers trust our machines and systems.

UL499: Compliance for Electric Heating Appliances
UL499 is an important certification for electric heating appliances. It covers products like space heaters, ovens, and other devices that generate heat using electricity. According to UL499, “For the purposes of this standard, a heating appliance is defined as an electrically energized product that directly or indirectly generates heat to perform its intended function.”1
If your product is UL499-certified, it means it has passed strict tests to meet safety requirements. For engineers, using UL499 recognized components ensures that the products will be safe and reliable in larger systems, such as machinery or equipment that require a UL listing.
The purpose of having a recognized part is to ensure that all aspects of the equipment adhere to the standards set forth by UL to make safe, reliable products. This includes:
- designs
- testing procedures
- materials
- manufacturing processes
Not all heaters are the same. However, when we compare heaters that meet the same UL499 standard, we find more similarities than differences at Tempco. Tempco manufactures each UL Recognized product line with its own section or file that describes how to make each product. Our Engineering Department designs each heater following these UL guidelines.
Tempco uses ISO standards across the company. This helps document every procedure and work instruction for all processes. This creates clear results for the company. It starts with the ordering process and ends with the customer getting a Tempco heater.

ISO 9001:2015 Certification for Quality
Tempco is also ISO 9001:2015 certified, which means we follow high standards for quality management. This certification ensures that our manufacturing processes are well-documented and consistently meet customer expectations. When you use our products, you can trust that they have been made with high quality, and the manufacturing process is efficient and controlled.
FM Approval: Fire Safety and Reliability
For some of our products, we hold FM Approval. This certification is critical for products that need to meet high fire safety standards. Engineers designing systems with FM-approved products know they are working with materials that are safe and have been rigorously tested for fire prevention and safety.
Why Third-Party Certifications Matter
When designing and building machines, it’s important to use heating equipment and components that are regulatory compliant. Products with third-party certifications like UL499, UL508A, and FM Approval help ensure that the equipment meets safety standards. This means fewer risks, safer products, and more reliable systems for your customers.
