In the context of wind uplift testing, which organization defines the procedures?

• A. ASTM.
• B. FM Global.
• C. IBC.
• D. NRCA.

Answer: (A)

Wind uplift testing relies on standardized procedures so results are consistent across labs and products. The organization that defines these procedures is ASTM International, which publishes the official wind uplift test methods used for roofing systems. These methods spell out how to prepare specimens, how to apply controlled wind loads (positive and negative pressures), test duration, acceptance criteria, and how results are reported. This standardization lets you compare ratings and approvals across manufacturers and jurisdictions and aligns testing with code and certification processes. The other organizations play important roles in the industry—FM Global develops risk-based testing protocols for their own assessments; the IBC references recognized standards but does not publish the wind uplift procedures itself; NRCA provides guidelines and best practices, not the formal, universally adopted test methods. So, ASTM International is the body that defines the procedures.
