The FGIA has retooled a document determining test methodology for laboratory and field testing of exterior wall systems.

The Fenestration and Glazing Industry Alliance (FGIA) has retooled a document determining test methodology for laboratory and field testing of exterior wall systems. This includes curtainwalls, storefronts, window walls and sloped glazing containing products covered by AAMA 501-24, “Methods of Test for Exterior Walls.” The document was last updated in 2015.

AAMA 501-24’s mandatory and optional test methods evaluate the performance of a complete system. They do not replace structural calculations and/or accepted engineering practices. The test methods, specifications, field tests and checks referenced in the document are used to check the structural adequacy of wall system test specimens and their ability to resist water penetration and air leakage.

Optional tests for thermal cycling, inter-story displacement, static and dynamic seismic racking, acoustical performance and thermal performance, some of which require additional test specimens, are also referenced.

“The document had a thorough review and revision performed to clarify how it could be used for various purposes which had been outside of the limited scope of previous editions,” says Rich Rinka, FGIA technical manager of Fenestration Standards and U.S. Industry Affairs. “To help make the document a little easier to use, the tests have been placed into a table that provides a logical sequence for the testing to be conducted and highlights required tests and optional tests.”
