In North America, fire rated steel doors are certified to UL 10C (positive pressure) or UL 10B (neutral pressure) standards, with ratings ranging from 20 minutes to 3 hours. The rating you need is determined by the fire-resistance rating of the wall the door is installed in, the occupancy type, and the local building code.
