When using structural standing-seam metal panel systems, which testing standard is primarily acceptable?

The primary testing standard accepted for structural standing-seam metal panel systems is ASTM E1592. This standard specifically evaluates the structural performance of metal roof panels under various conditions, including load resistance and deflection. It is crucial for manufacturers and installers to adhere to this standard to ensure that the metal panels can withstand environmental stresses such as wind loads, snow, and other structural forces.

FM 4474, while relevant to roofing systems, primarily pertains to wind uplift testing and is not focused on the structural integrity of standing-seam panels specifically. The International Building Code (IBC 2015) provides general guidelines for construction standards but does not set specific testing protocols for standing-seam metal panel systems. The option "None applicable" does not apply since there is indeed a recognized standard for this type of roofing system. By conforming to ASTM E1592, individuals involved in roofing can ensure compliance and safety in their installations.
