The Fenestration and Glazing Industry Alliance (FGIA) has released a new technical information report (TIR) establishing criteria for deflection and permanent deformation gauge device locations to meet uniform deflection and structural load test specifications and requirements specific to horizontal and vertical sliding windows and doors. AAMA TIR-A19-22 Structural Test Deflection and Permanent Deformation Gauge Placement for Horizontal and Vertical Sliding Windows and Sliding Doors is now available for purchase.
This TIR describes the correct placement of deflection measurement devices, and calculations for determining deflection and permanent deformation when performing structural testing of horizontally and vertically sliding window and sliding door products under uniform static air pressure difference per ASTM E330 and/or AAMA/WDMA/CSA 101/I.S.2/A440. The proper use of this TIR requires knowledge and training in the principles of fenestration testing.
AAMA TIR-A19 is the third in a series of three technical information reports on the structural testing of windows and doors, its counterparts being Structural Test Deflection and Permanent Deformation Gauge Placement for Single-Point Lock Side-Hinged Door Systems and Structural Test Deflection and Permanent Deformation Gauge Placement for Fixed and Compression Seal Windows.
