AAMA 925-17, the Specification for Determining the Vertical Loading Resistance of Side-Hinged Door Systems, determines the ability of a side-hinged door slab to remain operable following the application of a vertical load along the lock stile. It was last updated in 2013.
“AAMA 925 has been updated to remove the collection of data-only methodology and incorporated a simplified pass/fail approach to the test,” said Chad Elbert (JELD-WEN), Chair of the Side-Hinged Auxiliary Test Method Task Group.
“To ensure that a door leaf(slab) design can withstand a reasonable vertical load on the lock stile and remain operable, the pass/fail criteria is to validate the leaf (slab) will still close within the opening. The prior approach collected data-only with now pass/fail limitations.”
Additional edits to this updated standard include the replacement of the term “door leaf” with “door slab,” as well as a section clarifying what kinds of slabs may qualify other slabs.
