AAMA releases new document on static water test pressures in non-hurricane regions
The American Architectural Manufacturers Association, Schaumburg, Ill., released the AAMA TIR A13-09, which provides information in regards to resistance to wind-driven rain penetration, according to a March 23 release. Resistance to wind-driven rain penetration is one of the primary functions of fenestration systems and is addressed by many industry standards, building codes and project specifications.
AAMA/WDMA/CSA 101/I.S.2/A440 provides the specifying authority, builder and consumer with some latitude in selecting an appropriate maximum water test pressure. AAMA TIR A13-09 provides information on recommended maximum static pressures used during testing of products' resistance to wind-driven rain penetration, when such tests are conducted as part of the AAMA/WDMA/CSA 101/I.S.2/A440 regimen, according to the release.
"Though technical in nature, it is the intent of the document to present this information in clear 'layman's' language and is based on the accumulated experience and expertise of AAMA's members and staff," said Ken Brenden, AAMA technical standards manager, in the release. "Recent work by ASTM and AAMA has been focused on testing and rating of fenestration products that are intended for use in areas subjected to extraordinarily severe rain conditions, as experienced during tropical storms and hurricanes, but this report is applicable in all areas of the country due to storms, tornadoes and other non-hurricane weather conditions."
This Technical Information Report is limited to water resistance testing, although there is some degree of correlation with design wind pressures for a given site and application. Catastrophic structural damage and life safety concerns may lead to a greater degree of conservatism in structural design than is appropriate for water penetration resistance. Structural performance and wind-borne debris damage are not covered in this document, according to the release.
