SPRI, the association representing sheet membrane and component suppliers to the commercial roofing industry and the Metal Construction Association (MCA), an organization of manufacturers and suppliers of metal products used in the building envelope, are working together to update and recanvass the ANSI/MCA FT-1 standard, “Test Method for Structural Performance of Flashings Used with Metal Roof Systems”.
“Test Method for Structural Performance of Flashings Used with Metal Roof Systems” evaluates the structural performance of flashings associated with metal roof systems by testing the flashing and its attachment to the support material using line loads. The provisions of this test method apply to exposed flashings with a face of 4″ or greater that are direct-fastened, and hem-and-cleat connections or other attachment methods with a face of 2″ or greater. Two methods of testing are provided: 1) Face Load; and 2) Face Load and Top Load. This test method provides a standard procedure to demonstrate structural performance under uniform line load and is intended to represent the effects of uniform loading on exposed elements of the building surface.
MCA developed this test method in 2017 and it was first approved as an American National standard in 2019. It is now being reviewed and recanvassed as required by ANSI procedures.
Those wishing to participate in the canvassing process should contact SPRI at [email protected].
