Question

Quizplus · Accepted Answer

Fire-resistance rating of an assembly is measured in time, which indicates the amount of time that an assembly can resist the spread of fire. For example, a wall or door assembly with a fire-resistance rating of "1 hour" can resist fire for a duration of 1 hour, while still maintaining its structural integrity and limiting the spread of fire and smoke.
