I cannot find a design using the online search tool Product iQTM but it can be found in the hard copy directory. Why? Or, I can find a design using the online search tool but not in the hard copy directory.
Certifications for tested designs are periodically “withdrawn” or removed from our records. This can occur for several reasons:

  • One of the test sponsors (a manufacturer of a product listed within the design) is no longer in business. Since one of the products is no longer available the design cannot be replicated as originally tested.
  • The building codes mandate that the products listed within tested designs must be audited annually. The test sponsor may no longer want to maintain the audit.
  • A test sponsoring company may get bought by another company; sometimes the new company is unaware of the contractual relationship with UL and the certification will lapse.
  • UL is constantly testing new designs every week. The hard copy directory is a “snap-shot” in time, any design tested between the publication of the directories can only be found using the online search tool Product iQTM.
