Abstract: During designing of fire rated doors more importance is given to the door shutter as compared to door frame for achieve given fire rating. On the contrary, it is observed in various events that, even if the fire rated door resists fire, the failure occurs in frame because of wrong selection of wood, resulting in non-conformity or failure of door set for achieving the desired fire rating. This study is carried out to correlate the density of wood used in frames of door shutter assemblies with its rate of burning. Some of the widely used species for frames of fire rated door were selected for the study viz. Red meranti (Shorea acuminata), Sal (Shorea robusta), Birch (Betula pendula), Padauk (Pterocarpus spp.), White Meranti (Shorea spp.). Samples of different densities ranging from density of 412 to 849 Kg/m3 were tested for rate of burning as per Indian standard IS 1734 (1983). The correlation of fire performance/ rate of burning was drawn with respect to density of wood. From the results of the study it is observed that lower rate of burning of wood is observed with denser wood, hence it can be said that fire resistance of wood increases with density.
