Using a fire-resistant ceiling in any building helps prevent the rapid spread of fire, smoke and heat through the building’s floor-ceiling system by limiting the extent and duration of a fire within one compartment of a building.

When talking about the seismic deformation of suspended ceilings, it means the fragility of these ceilings. There are many tests to check the deformation of these suspended ceilings.

It's essential to know about standard classification for acoustical ceiling products when doing structural projects. The ASTM E1264 deals with this when finding the right finishing for buildings.
