The Fire Endurance test subjects a full-size window or door assembly to a controlled time-temperature profile in a furnace. The test duration is 20 minutes up to three hours, depending on the desired rating, with temperatures reaching nearly 2000 °F in three hours. The window assembly including frame, glazing and components must not allow flames on the non-fire side, and the glazing must survive the test without breaking or cracking.

Immediately following the Fire Endurance test, the fire-exposed side of the test assembly is subject to impact from water blast in a  prescribed pattern for duration appropriate to the specimen size. The glazing must remain intact in the frame.
