Wood fire doors with surface damage

Hi all, I'm relatively new to the world of fire door inspection, but I do have formal training.


I see a lot of old wood fire-rated doors with missing patches of surface wood veneer, and edge and surface cracks into the veneer. Also doors missing corner chunks. Can anyone give me some guidance as to what is acceptable, and what is not? Obviously penetrations to the mineral core are verboten, but how much surface material loss is "too much", resulting in the door failing? And, are there any acceptable fixes for this type of damage? I am aware of fire door caulk for open screw holes, and I do use it.


Thanks for your help,
