AAMA Updates Specification for Vertical Loading Resistance of Side-Hinged Doors

The American Architectural Manufacturers Association has updated and released AAMA 925-13, Specification for Determining the Vertical Loading Resistance of Side-Hinged Door Systems, which determines the ability of a side-hinged door system to remain operable following the application of a vertical load along the lock stile of the door leaf, according to an Aug. 28 AAMA release.

Through the life of a side-hinged door system, there may be several causes of an extraordinary vertical load to be applied to the door leaf. The door loads in AAMA 925 are based upon the pullout values of hinge fasteners in wood, and the specification determines the effects of such loads when applied to a side-hinged door system. Although the deflection and permanent set results are not used in the qualification of the tested side hinged door system, these results are recorded for potential future use in AAMA 925.

“The revised version of AAMA 925 was made possible by contributions from task group members representing a cross-section of door component manufacturers and test laboratories,” Mark Fortun of Endura Products, and Chair of AAMA’s Door Vertical Loading Task Group, said in the release. “Changes enhance the clarity and flow of this test procedure and set the stage for a consistent means to evaluate the resistance of a side-hinged door assembly subjected to intentional high loading conditions.”
