Question 2

Correct Answer:

Verified

It is (primarily)determined through laboratory testing.

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?

Question 3

Correct Answer:

Verified

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 t ignite combustibles in contact with it, taken as 250°F above ambient temperature.
