The UL Component Recognition Classification

Gain an understanding of UL Recognized Components and learn why they are important for code authorities.

The UL Recognized Component Mark is important to the code authority audience. It indicates that a component has demonstrated compliance with applicable UL Standards, lending confidence and supporting a streamlined path to end-product certification. Below is a summary of the most relevant information to help you better understand the Mark and its application:

  • Purpose – Certification is for components and subassemblies intended to be built into a larger, UL Certified (Listed) end-product. It allows end-product manufacturers to use pre-tested components, simplifying the product certification process.
  • Mark – The UL Recognized Component Mark is distinct from the UL Listed Mark. It features a stylized backward "R" and "U" and is not contained in a circle.

Three variations of the UL Recognized Component Mark are used: one for the U.S., one for Canada, and one covering both the U.S. and Canada.

  • Conditions of acceptability – A crucial aspect of this certification is that components are evaluated under specific conditions of acceptability. These conditions dictate how the component must be used within the final product to maintain its safety rating. For example, it may specify things such as the type of housing, wiring or temperature limitations. Using a component outside of these conditions can void the certification.
  • Database – UL Solutions online database, UL Product iQ®, allows manufacturers and designers to find recognized components and review their specific conditions of acceptability. This helps ensure that the components they choose are suitable for their end-product application.
  • Examples – Examples of UL Recognized Components include appliance wire, cable assemblies, power supplies, circuit boards, plastics, switches and motors.

UL Component Recognition is a valuable tool for manufacturers to streamline their development and certification process by using pre-certified parts, but it is not a certification for a complete, standalone product.
