UL provides the latest fire testing capabilities to the damper industry. With unmatched experience and insight, we have helped write many of the industry test standards that are referenced in building codes. Our building materials team tests dampers for various safety aspects, including fire resistance, smoke leakage performance, corrosion and cycling. We offer full fire testing, with both large- and small-scale furnaces available in horizontal and vertical orientations and with access to airflow testing capabilities for single- and multiple-section dampers. UL also has the capability to test ceiling dampers in both combustible- and noncombustible-rated floor-ceiling designs, with the option of small-scale horizontal testing for alternative ceiling damper constructions. Testing and certification are also available for Canadian Standards. We offer extensive labeling capabilities for manufacturers of fire dampers, smoke dampers, combination fire and smoke dampers, and ceiling dampers. Field labeling (inspections and evaluations) services are available for damper products. Our worldwide reach, with an established presence across North America, Europe, Asia and the Middle East, makes it easy for customers to utilize UL services.
