Fire-Rated Door Compliance Is More Than a Door Rating
Fire-Rated Door Compliance Is More Than a Door Rating
A door marked FD30 or FD60 should not be assessed only by the number shown on its label.
The fire resistance performance normally relates to a complete tested assembly that may include:
🚪 Door leaf 🖼 Door frame 🔥 Intumescent seals ⚙️ Hinges and ironmongery 🔒 Lock or latch 🔁 Self-closing device 🏷 Certification label
One of the most common practical problems is the door closer.
A fire-rated door should return to the fully closed and latched position after use. If the closer is damaged, poorly adjusted or removed, the door may remain partly open and fail to support effective compartmentation.
The Certificate of Conformity should also be checked before changing components. Replacing the closer, lock, frame or seals with an unrelated product may move the installation outside the certified configuration.
Useful checks include:
Is the certification label visible?
Does the closer fully latch the door?
Are the seals intact?
Does the frame match the certified system?
Has the door been cut, drilled or modified?
Is the CoC available for verification?
