A wall tested according to e 119 undergoes both fire exposure and water hose stream testing.
Solid concrete wall fire rating.
Where all of the core spaces of hollow core wall panels are filled with loose fill material such as expanded shale clay or slag or vermiculite or perlite the fire resistance rating of the wall is the same as that of a solid wall of the same concrete type and of the same overall thickness.
Fire resistance rating or fire rating is defined as the duration of time that an assembly roof floor beam wall or column can endure a standard fire as defined in astm e 119 3.
Concrete masonry walls are often used for their ability to isolate continue reading sound.
As an example a wall with a fire resistance period of 2 hours and 25 minutes may only attain a fire resistance rating of 2 hours.
Structural function or both.

It is also referred to as a fire rating fire resistance classification or hourly rating.
These values are for solid walls or slabs.

The hose stream test provides a meaningful measure of.
Walls composed of hollow concrete masonry units having a nominal thickness of 8 inches or greater and having a fire resistance rating of at least 2 hours shall be classified as 4 hours when the hollow spaces are completely filled with perlite or vermiculite grout or a material such as expanded.
The fire resistance rating of reinforced and plain concrete walls floors and roofs depend on equivalent thickness of the element and can be found out using table 3.
51 mm thickness can be used.
The equivalent thickness of different types of concrete masonry is provided in the following.
