Testing is conducted by exposing the check assembly (walls, floor-ceilings, roof-ceilings, columns, beams, and horizontal membranes) to furnace circumstances that follow a specific time and temperature curve. The meeting should not fail structurally, both by the passage of flames or by the switch of heat enough to lift the unexposed surface temperature over a specified limit for the time of the ranking interval.
