Does the requirement for a maximum gap of 1/8″, plus or minus 1/16″, apply only to the meeting edges of door pairs? What is the gap requirement for maximum gap between door and frame/stop at the hinge jamb and head? And strike jamb on single doors?

If a metal door has a gap between the meeting edges of a door pair that is greater than 3/16″ (1/8″ plus the 1/16″ tolerance), can the deficiency be overcome by applying a metal astragal?
