Isaac Kremer/ July 3, 2024/ / 0 comments
The time in hours a material or assembly can be expected to withstand exposure to fire without collapsing, developing any openings which permit the passage of flame or hot gases, or exceeding a specified temperature on the side away from the fire, determined by subjecting a full-size specimen to temperatures according to a standard time-temperature curve. (Ching, 1995)
