A Focus on Door Standards and Testing
AAMA 920, Specification for Operating Cycle Performance of Side-Hinged Exterior Door Systems, was approved for publication at the Summer Conference last month. This document, scheduled for release later in July, addresses cycle testing under accelerated operating conditions for complete side-hinged door systems and their hardware. The document updates include:
- Basic clarifications of terminology to better define the scope of the document as cycling of side-hinged exterior door slabs and associated hardware connections
- Allowing the use of a cross-bar not only for glazed doors but also for raised panel doors
- Reference to AAMA 111, Procedure for Limited Component Substitution in AAMA-Certified Exterior Side-Hinged Doors, for guidance on one slab type and construction being permitted to qualify others
- Allowance for testing of glazed panels which are heavier than opaque panels to qualify the opaque panels
- Removal of performance requirements for door frames and system assembly since the scope is now limited to door slabs and associated hardware connections
Another major door-related development resulting from the Summer Conference was the decision to open the AAMA 111 procedural guide for revision to incorporate provisions to allow interchangeability of components for air and water performance. This initiative will include inviting representatives from Fenestration Canada and the Window and Door Manufacturers Association (WDMA) to provide input. Given the fact that the Canadian building code does not include an exception for side-hinged door compliance with NAFS, this is a critical issue for the Canadian construction market.
As reported in the May AAMA e-News, the Multi-Panel Door Testing for Certification Task Group is tasked to review testing and certification of multi-panel door systems not currently covered under NAFS (e.g., bi-fold, multi-slide, lift-and-slide, etc.). At the Summer Conference, the group moved forward with its plan to solicit input from Florida-registered Professional Engineers by inviting Hermes Norero (Building Drops Inc.) to speak on the following topics:
- Common Florida P.E. interpretation of the Florida Building Code requirements for comparative analysis as they pertain to qualification of multi-panel/multi-track sliding door systems with frame sizes larger than tested
- Qualification of components, as outlined in the Florida Technology Advisory Council (TAC) minutes from the April 8th, 2016 meeting
- Typical “best practice” procedures for developing a test plan
Members often remark about the vast breadth and depth of the work of our association – some aspects of which, such as the Door Council initiatives, are critically important to the industry but not as well known. Participating in national conferences and serving on task groups and committees (either in person or via conference calls) are among the best ways to stay informed about such activities. But, if you don’t have time for that level of engagement, at least be sure to read each monthly edition of the AAMA e-News and sign up for the AAMA website RSS feed to have critical information about these types of developments delivered right to you.
