There currently is a lack of credible fire performance test data for non-rated ceiling tile systems (NCTS). This study seeks to explore failure criteria for NCTS, and thermal resistance provided prior to failure. As part of this research, a testing apparatus was constructed to evaluate the performance of the NCTS with respect to the fire location, distance between the NCTS and a fire, and tile arrangements within the NCTS. Testing results were then compared against numerical model predictions of the observed temperatures. The results demonstrated that the NCTS provides a measurable level of thermal resistance during a fire and maintains its integrity for several minutes. Furthermore, it was shown that testing results can be generally represented using the numerical model.enHeat Transfer to CeilingsCeilingsFailure of Ceiling TilesSuspended ceilingsFire Performance Testing
