The American Architectural Manufacturers Association updated a document describing a standardized test to evaluate heat build-up effects due to infrared exposure on fenestration products. AAMA 1506-18, Voluntary Test Method for Laboratory Heat Build-Up Effects on Fenestration Products, intends to determine the effects of heat rise on fenestration product assemblies intended for vertical installation. This document was first released in 2004. This is its first update.

Changes to this standard include aligning Section 7.3.2.1 to ASTM D4803 rather than G179, because D4803 is specifically for building products. D4803 is also referenced in AAMA 303, Voluntary Specification for Rigid Polyvinyl Chloride Exterior Profiles, which was updated by AAMA at the same time. Additionally, a footnote was removed in order to maintain a consistent and standardized testing method.

“This test method exposes fenestration products to a uniform field of IR energy directed at the product at an angle similar to outdoor exposure during the summer months in hot and dry climates in the U.S.,” said Jeff Franson of Quanex Building Products, chair of the AAMA 1506 Vinyl Profile Heat Build-Up Task Group. “Changes made to this document now mean it, and AAMA 303, are more consistent when it comes to testing.”
