An engineering guide on organizing and executing Factory Acceptance Testing (FAT) for architectural facades and windows to verify air, water, and wind resistance.
Constructing and Preparing the Performance Mock-up Sample
A full-scale performance mock-up sample (typically two to three floors high, incorporating critical intersections and thermal expansion joints) is built and sealed against a specialized factory test chamber to simulate all structural conditions the actual building will face post-execution.
Air Infiltration Testing per ASTM Criteria
The technical protocol kicks off with air infiltration testing (such as ASTM E283) by vacuuming air to generate negative pressure inside the chamber, measuring air leakage across gaskets and joints to ensure filtration profiles sit within strict limits permitted by energy conservation codes.
Static and Dynamic Wind Load Resistance Testing
Massive hydraulic and pneumatic pressures are applied to simulate peak calculated wind profiles for the project's region (static and dynamic wind pressures). Engineers utilize precise digital displacement sensors to measure aluminum frame deflection, ensuring zero permanent deformations or glass structural breakage under abrupt high pressures.
Analyzing Results and Certifying the Line for Heavy, Continuous Project Production
Upon the sample successfully clearing all performance protocols (including dynamic water tests using aircraft propellor engines to simulate storm conditions), the lab issues the official compliance certificate. This technical clearance allows plant management to signal the green light for high-volume mass production with absolute engineering confidence.
