Updated AAMA 502-12 addresses newly installed fenestration products

June 1, 2012 - AAMA 502-12 Voluntary Specification for Field Testing of Newly Installed Fenestration Products has been published by the American Architectural Manufacturers Association (AAMA). This updated specification establishes the requirements for field test specimens, apparatus, sampling, test procedures and test reports to be used in verifying the air infiltration resistance performance and water penetration resistance performance of newly installed fenestration products. Revisions to AAMA 502-12 also include the addition of the CW class and removal of C and HC classes as performance classes in examples of allowable air leakage rate, which is in keeping with the recently updated AAMA/WDMA/CSA 101/I.S.2/A440-11, North American Fenestration Standard (NAFS).
