FM Cetificate For Hollow Metal Door

- Jun 21, 2019-

All FM Approved fire doors are evaluated based on full-scale fire testing. Based on the results of these tests, each door receives a fire resistance rating to indicate the acceptable duration of the fire exposure.


Fire doors can also be provided with a temperature transmission rating which provides the anticipated temperature rise developed on the unexposed surface of the door after 30 minutes of fire exposure.
