AAMA Updates Testing Standards for Adhesive Bonding of SDLs to Glass

Posted on 10/2/2019 7:10:47 AM By ASC

The American Architectural Manufacturers’ Association (AAMA) has taken a new look at its standards with regard to the voluntary testing of adhesive systems used to bond simulated divided lite bars (SDLs) to glass, and has updated the relevant specifications for the first time since 2011.

According to the AAMA the previous rulings requiring only minimum criteria for adhesive systems were reworked, and UV testing references were updated to bring tapes’ peel adhesion requirements in line with liquid adhesive systems, and to clarify how test results were to be reported.

The update specifies that the voluntary tests on standardized SDL bars and substrates must determine the adhesive system’s ability to remain uncompromised from the point of installation through a variety of weathering conditions. However, the association has recommended that the testing process be taken further, and carried out on finishes and materials as and when they are chosen, in order to determine their suitability for specific fenestration projects.
