Very few people get the chance to witness fire door testing in person. Conceptually, we understand that doors are subjected to extreme fire conditions under laboratory conditions prescribed by one of the national fire door test standards (e.g., NFPA 252, UL 10B, and UL 10C). Even so, it is difficult for us to imagine the affects fire has on swinging doors.
The video shown in this course is published by the Steel Door Institute (SDI) and is very informative regarding how fire door tests are conducted, and how steel doors perform under these intense conditions.
