What is the Fire Rating for an FM Approved Door?

7/16/2020

I recently investigated some fire doors at one of our older buildings and saw they have an FM Approved label on them instead of a common UL Listing. I'm used to the UL listing label which clearly states the fire rating in minutes or hours. The FM label I saw gives some outdated ASTM standards and references a CABO report but doesn't clearly state the fire rating.

Does anyone have experience with the FM Approved fire door labels?

Based on my research, FM stopped approving fire doors a while ago. Thanks in advance.

The fire door label should have an hourly rating on it listed above the FM Global testing standard that was used to test it. Otherwise, you'll have to track down a fire door manufacturer and model to look in the approval guide. All else fails, hopefully the doors are tested and the testing reports may have the fire rating on them. However, that should be a last ditch effort as those are not always accurate.

Agree with Anthony. FM approved doors are still compliant as long as the label is intact.
