Which of the following is not a requirement for a fire-rated floor-ceiling assembly in a commercial building?

Non-combustible materials
Labeled with a fire rating
Continuous from wall to wall
Minimum thickness of 50 mm

The correct answer is: Minimum thickness of 50 mm

A minimum thickness of 50 mm is not a specific requirement for a fire-rated floor-ceiling assembly in a commercial building. The other options, including non-combustible materials, a labeled fire rating, and continuous construction from wall to wall, are all essential elements for a fire-rated assembly to effectively contain and prevent the spread of fire. While a minimum thickness may be recommended for certain types of fire-rated assemblies, it is not a universal requirement and may vary depending on the materials and construction used. Therefore, D is not a correct requirement for a fire-rated floor-ceiling assembly in a commercial building.
