In what units is fire resistance measured? How is the fire resistance of a building assembly determined?

Fire resistance is measured in hour.

Explanation:

The fire resistance of the structure is estimated in a number of hours during which material and a piece of the structure can oppose a fire. The fire resistance of a joining structure is dictated by the type of structure, the supporting dividers, the segments, the bars, and the supports. The table shows the fire resistance level of most of the structure's segments.

While deciding the level of free opposition, the cost will be higher. In this way, the structure is planned with the least tightness at the fire level authorized by the building law.
