AAMA Releases New Voluntary Specification for Rating the Severe Wind-Driven Rain Resistance of Windows, Doors and Unit Skylights
June 15, 2009

The American Architectural Manufacturers Association (AAMA) has released AAMA 520-09, a voluntary specification for windows, doors and unit skylights. Titled Voluntary Specification for Rating the Severe Wind-Driven Rain Resistance of Windows, Doors and Unit Skylights, the specification provides an optional rating of the ability of fenestration products to resist severe wind-driven rain.

The release of AAMA 520-09 completes a 12-month review process led by the AAMA Southeast Region during which the document was evaluated and then shared with AAMA-accredited testing laboratories and other members to ensure that the specifications are clear and the test protocols yield repeatable results.

This voluntary specification is based on a rapidly pulsed pressure differential method, recognizing that conditions encountered during tropical storms, hurricanes or severe thunderstorms are not static. In addition, the procedures and equipment required to perform the specified tests are provided. The specification details the testing apparatus used; defines test specimens and installation and describes test methods utilized, as well as stating what information the test report should include.

The Voluntary Specification for Rating the Severe Wind-Driven Rain Resistance of Windows, Doors and Unit Skylights is available to members at a cost of $15 for download, $30 for paper copy and $35 for CD. Non-members may purchase the document at a cost of $37.50 for download, $75 for paper copy and $80 for CD.
