FD30 Doors - Door stops

[Guest Charlie B]

I have had fire doors installed in a property by a contractor. Some of the walls are 45mm and the installer has installed the doors in frames cut down and used the architrave as door stop by overhanging the edges 12mm over the door frame.  He believes the architraves suffice as door stop.  It is quite unusual I have not seen it before.

Would this pass a fire door assessment as we are converting the house for social care FD30 doors were recommended for all the rooms.

For most fire doors, the performance certification requires the wall to be at least 70mm thick.  I am yet to see one where such a thin wall is suitable.
