Fire Resistance Tests on Wall Composed of Wooden-Based Board with Various Construction Specification on Heated Surface

Fire resistant tests are conducted on full scale specimens of wooden wall that sets up wooden-based board on heating side were carried out. The furnace at Tokyo University of Science was used. As the result of experiments, the temperature of each part of the wall was not able to confirm a remarkable difference by the wood species and installation method. But in-crease in board thickness and fire retardant treatment brings the delay of the temperature rise. The temperature rise of unexposed surface of wooden-based board became rapid after it reached 260 ℃ . The time which temperature of exposed surface of plywood reached 260 ℃ was 1~4 minutes later than the time which temperature of unexposed surface of wooden-based board reached 260 ℃ . Abstract
