Make sure windows and glass blocks don’t contribute to fire spread by following the testing provisions in the 2012 NFPA 257. NFPA 257: Standard on Fire Test for Window and Glass Block Assemblies prescribes fire and hose stream test procedures that apply to fire window assemblies — including window, glass block, and other light-transmitting assemblies — intended for use in window openings to retard the spread of fire through openings in fire-resistive walls. It establishes controls of the fire test as well as performance criteria and results for reporting procedures. NFPA 257 is referenced by NFPA 101\u00ae: Life Safety Code\u00ae when being used to set up a window fire resistance rating in a fire rated wall assembly. Essential for testing laboratories and manufacturers, the 2012 Standard edition contains updated references to ensure you’re working with the latest information.<\/p>\n
