Standard: UL 1784 – Standard for Air Leakage Tests of Door Assemblies and Other Opening Protectives

Scope: The investigation of air leakage at ambient and elevated temperature through door assemblies and other opening protectives installed in wall openings where air leakage is intended to be controlled. Gasketing systems can also be tested by installing in a standard door assembly.

Applicable Products: Complete door assemblies, opening protectives, or gasketing systems intended for use with specific door assemblies.

Test Procedure:A complete door assembly or opening protective system is installed in a test frame to represent the typical field installation and cycle tested to measure the latch and closing force. Then the assembly is tested to determine the rate of air leakage at an ambient temperature condition (75°F +/- 20°F) and an elevated temperature condition (400°F +/- 10°F). The rate of leakage is measured as cubic feet per minute per square feet (cfm/ft2) of the test sample.

End Result: Reporting of the assembly closing and latch force (if applicable) as well as the air leakage rating (largest leakage rate determined) conducted after the cycling tests. A comprehensive test report will be issued at the end of the conclusion of testing. Intertek Certification is available to confirm compliance with the 3.0 cfm/ft2 maximum air leakage rate required by NFPA 105 and the International Building Code.
