How deep to cut fire door frame for hinges?

Is there any regulation on how deep to chop the 4 inch butt hinge, does it have to have one leaf chopped into the door and one into the Frame? Or is it ok to chop the hinge double depth into the door and screw the other leaf to the frame and not chop into the Frame

    I am not a chippy but the normal is sinking the hinge into both the door and the frame what you are suggesting could affect the fire resistance, if a fire door.
