Standard Practice for Evaluating Elevated Temperature Performance of Adhesives Used in End-Jointed Lumber

Importancia y uso:

5.1 End-jointed lumber studs used in fire resistance-rated assemblies shall be able to support the superimposed design load for the specified time under an elevated temperature exposure, when a wall assembly is exposed to a standard fire specified in Test Methods E119. Light-weight wood assemblies utilize gypsum wallboard or other types of membrane protection to accomplish a requisite fire resistance rating for the assembly. However, wood studs and the end joints in the studs shall resist the developed elevated temperature environment for the duration of the rating. This practice provides a method for evaluating the elevated temperature performance of an adhesive used in end-jointed lumber as compared with the elevated temperature performance of solid wood.
