CAN/CSA A123.21-04 PDF

This test method determines the wind uplift resistance of mechanically attached membrane-roofing systems subjected to dynamic wind load cycles. The roofing system consists of a deck and roofing membrane. It also includes components such as air/vapour barriers or retarders and insulation. It is subjected to a dynamic load sequence that has been developed based on wind pressure records, simulating the effects of wind on membrane roof assemblies.
