SPRI, the association representing sheet membrane and component suppliers to the commercial roofing industry, announced that it is reviewing the FX-1 Standard for re-approval as American National Standards.

ANSI/SPRI FX-1 Standard Field Test Procedure for Determining the Withdrawal Resistance of Roofing Fasteners and plans to canvass the document for re-affirmation as an American National Standard in the coming months. SPRI developed this standard for measuring the pullout resistance of roofing fasteners in field conditions. It was first published in 1996 and, in accordance with ANSI requirements, has been re-canvassed every five years. It was last updated and approved by ANSI in 2021. 

Those wishing to participate in the canvass process should contact SPRI at info@spri.org.
