1-1.1 These methods of fire tests apply to assemblies of masonry units and to composite assemblies of structural materials for buildings, including bearing and other walls and partitions, columns, girders, beams, slabs, and composite slab and beam assemblies for floors and roofs. They also shall apply to other assemblies and structural units that constitute permanent integral parts of a finished building. 1-1.2* It is the intention of this standard that classifications be based on performance during the period of exposure and shall not be used to determine suitability for use after fire exposure. 1-1.3 The results of these tests are one factor in assessing fire performance of building construction and assemblies. These methods prescribe a standard fire exposure for comparing the performance of building construction assemblies. Application of these test results to predict the performance of actual building construction requires careful evaluation of test conditions.
