The American Architectural Manufacturers Association (AAMA) released an updated document describing the test procedures and specifications of Architectural Class doors and windows (AW).

This specification and test method is intended to model, through accelerated testing, the normal wear that can be expected during the life of a typical AW product. The AAMA 910-16, “Voluntary Life Cycle Specifications and Test Methods for AW Class Architectural Windows and Doors,” was last updated in 2010.

“AW windows and doors, covered in AAMA/WDMA/CSA 101/I.S.2/A440 (NAFS), are the only fenestration product types that go through accelerated life cycle testing including operating and thermal cycles followed by structural, air and water tests,” says Kawneer’s Greg McKenna, chair of the AAMA 910 Lifecycle Testing Review Task Group. “AAMA 910 is an important document as it is referenced in NAFS and lists the sequence of tests to be conducted on these high performing products.”

According to AAMA, enhancement of performance requirements—to include thermal cycling and increase the number of operating cycles, as well as increased misuse loads—helps to differentiate AW products from other Performance Classes. In addition, descriptive language has been clarified.
