![]() One of the more obvious critical elements for a properly installed SFRM is its applied thickness. Furthermore, in the laboratory the environmental conditions for the preparation of a test assembly, such as temperature and the presence of obstructions, are controlled, whereas environmental conditions at a job site are subject to change in ways that could inhibit proper SFRM preparation and application. However, on the construction site, the skill level and training of the installers cannot be controlled. In the laboratory, only the most skilled laborers are used for preparation of the structural test assemblies to ensure that the tests perform as expected. For this reason, field verification of SFRM installation is critical to the building commissioning process. The controlled environment and care associated with preparing a structural test assembly for the laboratory fire endurance test can vary greatly with the amount of time and attention available during the application of SFRM to a structural assembly in the field. These standards, specifically ASTM E 605 2 and ASTM E 736, 3 form the basis for the testing and commissioning process for SFRM. However, the method with which to field verify that the installation is consistent with the intention of the manufacturer and with the tests conducted in the laboratory is outlined in other ATSM standards. This includes the type of SFRM applied to the structural members, along with its minimum required thickness, density and bond strength. ![]() The relative fire resistance of an assembly is measured by its performance when subjected to standard fire endurance tests such as ASTM E119. Because of this, laboratory testing is used to evaluate fire resistance ratings for complete assemblies of structural members, including the characteristics of their applied thermal protection. Further, the ability of SFRM to protect a given structural assembly varies with the characteristics of the members being protected. The fire-resistive qualities of SFRM materials differ with the specific characteristics of each material, as well as the manner in which they are prepared and applied. SFRM materials come predominantly in cementitious-, gypsum-or mineral-fiber-based forms.
