What is the bond strength of SFRM calculated from a test cap area of 0.0576 square feet?

The bond strength of Spray-Applied Fire-Resistive Material (SFRM) is determined through standardized testing protocols that measure how well the fireproofing material adheres to the substrate. In the context of the question, the calculated bond strength reflects the performance of the SFRM when subjected to a specified test area.

A bond strength of 260 psf indicates that the SFRM has strong adhesion properties, crucial for ensuring structural integrity during a fire event. The strength of 260 psf likely meets or exceeds the requirements set forth by building codes and industry standards, allowing for effective protection against fire.

When addressing the bond strength values that are not chosen, they likely represent less effective performance ratings based on similar testing criteria. Thus, while other values may suggest adequate performance, 260 psf signifies a superior level of bonding, underscoring the importance of using materials that provide robust fire protection in construction applications.
