CAN/ULC-S112-M90：Standard Method of Fire Test of Fire-Damper Assemblies
Abstract 摘要
These requirements and methods of test apply to fire damper assemblies rated ¾ h, 1 h, 1½ 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.
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.
