Abstract
In recent years, fire-rated floor and wall assemblies formed with new materials and construction methods have been used increasingly in residential buildings. To determine the fire resistance performance of these assemblies, full-scale tests are usually required. However, these tests are expensive and time consuming, and there is a need on the part of design engineers and architects, at least in the development of assemblies, to find an alternative solution. To satisfy this need, the National Research Council of Canada (NRC)has been developing a simpler and less expensive test method for these purposes. As part of these efforts, NRC has just completed the construction of an intermediate-scale furnace that can be used for testing loaded and unloaded wall and floor assemblies. However, to ensure that this furnace reflects full-scale test results, it must be characterized. Heat exposure in the furnaces is one of the critical parameters in determining the fire resistance performance of specimens. This article presents results of the heat exposure characterization tests carried out by NRC in both its full- and intermediate-scale fire resistance floor test furnaces.
