UL certifications and UL Evaluation Reports provide the technical foundation relied upon by architects, designers, contractors and code authorities to provide safe, code compliant installations.

UL certifications and evaluation reports


UL certifications

UL product safety certifications and the trusted UL Mark assist in determining code compliance for products where the model codes require testing and/or certification in accordance with specific standards. Several free, easy to use online tools help locate these certifications, including:

  • UL Product Spec (www.ul.com/productspec) – Quickly find, specify, or verify UL Certified products for your projects
  • UL Code Correlation Database (www.ul.com/codelink) – correlates specific model code section numbers with applicable UL certification information
  • UL Online Certifications Directory (www.ul.com/database) – locate a UL Listing or Classification

UL evaluation reports

In some specific situations, code authorities use product evaluation reports to provide technical evidence that a new or alternative material, product, design or method of construction complies with the intent of the building codes. To satisfy this need, UL has been asked by customers to provide such technical evaluations through the issuance of UL Evaluation Reports. UL has vast testing experience, a strong reputation for technical excellence, thousands of UL product safety certifications within the built environment, intimate knowledge of the product and test standards referenced within the model codes, and full involvement with the model code development processes. UL Evaluation Reports are intended to provide guidance to code authorities, architects, designers, contractors, installers, and other built environment influencers in determining code compliance for products where:

    1. The product is not included in the model installation codes, or
    2. The model installation codes do not identify specific and clear requirements for the product, or
    3. The model installation codes have multiple requirements for the product not covered by a single standard.

These Evaluation Reports are based on the requirements in the model installation codes and other standardized requirements. UL Certifications and Evaluation Reports demonstrate product compliance with code requirements.
