Testing and certification of building materials

UL evaluates a wide range of products for fire resistance and performance including doors, door hardware, roofing products, gypsum board, and more. Fire testing can be conducted with full test capabilities in our Toronto laboratory or at global UL laboratory locations. Product groups for testing can include:

  • steel protection;
  • gypsum board and acoustical tiles;
  • roofing products;
  • dampers; and
  • doors, glazing, and hardware.

The path to safety certification

Early engagement – This advisory phase involves technical discussions surrounding UL’s testing and certification requirements and can help minimize delays and prevent redesigns.

Test program development – A UL engineer will work with the manufacturer to develop a test program, providing an accurate statement of work and a quote for certification.

Preliminary engineering evaluation – UL collaborates with the manufacturer to determine which tests to conduct. After each preliminary investigation, UL provides a detailed report of all test results.

Testing and certification – UL conducts all required tests and evaluations in accordance with the applicable standard(s). Upon confirmation of compliance, UL issues a certification report and schedules an initial production inspection at the manufacturing location(s) to confirm the production facility is ready and authorized to produce UL-certified products.

Factory production control (FPC) and follow-up services (FUS) – UL performs regular follow-up visits to the manufacturing location(s) to help ensure the products being produced are representative of the products evaluated during the certification program.

Online certifications directory – Certified products are entered into UL’s Online Certifications Directory. This directory is a valuable, free-of-charge resource used by stakeholders looking for products that have been certified in accordance with specific standards or requirements.
