AAMA 920-11, Specification for Operating Cycle Performance of Side-Hinged Exterior Door Systems, has been revised and re-published by the American Architectural Manufacturers Association (AAMA). Though a side-hinged exterior door may be opened and closed a half dozen or more times a day, over a minimal period of time, the door system must remain intact and operable if it is to maintain its resistance to environmental conditions.

AAMA 920-11 establishes a standard test method and set of performance criteria for side-hinged exterior door systems and their associated hardware under accelerated operating conditions. This test method is not intended to determine the useful life expectancy of doors in service as a result of the data obtained during the test. It will, however, provide an indication of the effects that cycling will have on the door and door hardware connections and provide minimum performance criteria for door systems in order to achieve a specified performance class and grade.

The specification was developed by AAMA’s Door Cycle Task Group, chaired by Larry Livermore (Architectural Testing Inc.). Updated from the previous 2003 edition of the document, the revised document includes a number of clarifications regarding the test specimen itself. In addition, the pass/fail criteria have been expanded to include many of the components used in a side-hinged exterior door.

The Specification for Operating Cycle Performance of Side-Hinged Exterior Door Systems is available to members at a cost of $10 for download, $20 for paper copy and $25 for CD. Non-members may purchase the document at a cost of $30 for download, $60 for paper copy and $66 for CD. To order AAMA 920-11, visit the AAMA Online Publication Store at www.aamanetstore.org.
