UL certification

UL is a global leader in testing, inspection, certification, auditing and validation. The UL Mark is the single most accepted Certification Mark in the United States, appearing on 22 billion products annually.

UL classified

UL’s Marks for our Classification service appear on representative samples of products that UL has evaluated with respect to specific properties, a limited range of hazards or suitability for use under limited or special conditions.

In the Classification service, UL determines that a manufacturer has demonstrated the ability to produce a product complying with UL’s requirements with respect to one or more of the following:

  • Specific risk, e.g., casualty, fire, etc.
  • Performance under specific conditions
  • Compliance with regulatory codes
  • Compliance with specific standards such as international standards
  • Other condition, as determined by UL

UL recognized

These are Marks consumers rarely see because they are specifically used on component parts that are part of a larger product or system. These components may have restrictions on their performance or may be incomplete in construction. The component recognition marking is found on a wide range of products, including some switches, power supplies, printed wiring boards, some kinds of industrial control equipment and thousands of other products.

Just as with the UL Listing and Classified Marks, there are three variations of UL’s Recognized Component Mark: one for the United States only, one for Canada only and one for both the United States and Canada.

Components covered by UL’s Recognized Component program are intended to be installed in another device, system or end product. They are to be installed at the factory, not in the field and they may have restricted performance capabilities that limit their use. When a complete product or system containing UL Recognized Components is evaluated, the end-product evaluation process can be streamlined.
