Fire resistance rating of building materials. According to national building code of india part 4 fire and life safety 2005 fire resistance is a property of either an element or material of building construction and is the measure of its ability to satisfy for a stated period of some or all of the following criteria. While no building materials are entirely fireproof building with fire safe products can help enhance resistance to heat and flame during a fire. A common fire test to evaluate fire resistance of walls uses a large vertical furnace figure 5 to expose a wall to radiant heat from gas burners. Depending on the construction and thickness of the wall a brick wall can achieve a 1 hour to 4 hour fire resistance rating.
A brick wall is held together with mortar which is less effective. Fire resistance tests elements of building construction part 10.
