Table 600 note i.

Side light in fire rated wall.

On fire rated transom and or sidelight frames and fire rated window frames steelcraft labeling procedures only control the o a width and or height of the frames based on wall condition. The testing and listing agencies have been testing and rating sidelites including the glazing component to the fire door test standard accordingly. Transom frame sidelite frame assemblies are tested and listed for fire protection in accordance with ul10c and nfpa 252. Where fire protection ratings are required fire protection rated glazing shall be installed.

Fire rated glass is tested the same way that other fire rated materials are tested. Fire rated glass testing. These wall assembly files are used for planning and estimation purposes for many ul wall types such as fire rated wall assemblies. Fire rated systems are critical life safety components and need to be thoroughly reviewed in both the design and construction phases to ensure they meet code requirements.

Under nfpa 80 the side light frame and the glazing in the frame are considered part of the door assembly and are tested to nfpa 252 the fire test standard for doors.
