How does the required hose stream test work and why does it matter?>
What do I need to know about impact safety testing for fire-rated glazing?>
Can fire-rated glass pass any additional performance tests?>
To receive a fire rating, glass must first pass a fire test in which a large furnace heats window frames or doors holding the glass sample. The assembly must remain intact for the duration of the test; there can be no flaming on the exposed surface of the assembly or openings.
