UL Recognized = Enhanced Market Acceptance

PWB components and materials that are recognized by UL are known to have undergone the industry’s most stringent safety testing and follow-up program. UL Recognized Components are listed in UL’s Online Certifications Directory www.ul.com/database and the UL iQ™ database iq.ul.com/pwb. This allows your customers to search and identify the components and materials they need to complete their subassemblies or end products.

Certification is driven by end-product requirements. The actual PWB ratings required are dependent on the end-product application and how the PWB will be employed. Always check with the end-product manufacturer to determine what ratings they require. Many end-product standards, such as the following, require UL Recognized PWBs:

  • UL 60950 – Information Technology Equipment
