Scope:
These requirements and methods of test apply to fire damper assemblies rated 3/4 h, 1 h, 1-1/2 h, 2 h, or 3 h for use in air-conditioning and ventilating system ducts or openings (without ducts) piercing horizontally or vertically oriented fire separations where the fire separations are required to have a fire resistance rating of not more than 4 h.
These fire damper assemblies are intended for installation in accordance with the provincial or municipal building regulations that are based on the National Building Code of Canada.
Tests made in conformity with these test methods will register performance during the fire-test exposure under laboratory conditions; but such tests shall not be construed as determining suitability for use after exposure to fire.
It is the intent that tests made in conformity with these test methods will develop data to enable regulatory bodies to determine the suitability of damper assemblies for use in locations where fire resistance of a specified duration is required.
Fire dampers are evaluated for use as either:
A Fire Dampers for Static Systems – For HVAC systems that are automatically shut down in the event of a fire or for air transfer openings in walls or partitions;
B Fire Dampers for Dynamic Systems – For HVAC systems that are operational in the event of a fire.
A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this Standard does not comply with this Standard.
Project need:
There currently is a reference to NFPA 90A-02 in 4.3.4 Exception B. The referenced edition of the NFPA standard (2002) is currently unavailable on NFPA read-only standards. Sleeve thickness, if required by this standard should be clearly indicated. NFPA 90A is not used in the National Building Code of Canada and should be removed to avoid confusion. NFPA 90A-2024 refers to the manufacturer's instructions, listing and SMACNA Fire, Smoke and Radiation Damper Installation Guide. However, the SMACNA guide should not be used if it conflicts with the manufacturer literature and is not proposed to be included in S112.
