In determining the fire rating of an assembly through laboratory testing, an important criterion to meet is that it should maintain its structural integrity for the duration of its fire rating. What other criterion/criteria should the assembly satisfy during that duration?
What will be an ideal response?
1. The assembly should remain smoke tight, i.e., not develop any cracks for the duration of its fire rating.
2. The temperature of the face of the assembly, not exposed to furnace fire, should not become so high as to ignite combustibles in contact with it, taken as 250°F above ambient temperature.
