What is the acceptance standard for SFRM thickness measurements on W-shaped columns?

The acceptance standard for Spray Fire-Resistive Material (SFRM) thickness measurements on W-shaped columns requires that all measurements must be above the specified thickness. This ensures that the fire protection performance of the columns meets the necessary safety requirements and regulatory standards.

Maintaining the specified thickness of SFRM is crucial because it directly influences the fire-resistance rating of the structural element. If the thickness is below the specified requirement, the structural integrity may be compromised during a fire event, potentially leading to catastrophic failures.

Thus, adhering to the standard of having all measurements exceed the specified thickness guarantees that every part of the column is adequately protected against fire, reflecting the critical importance of uniformity in application and compliance with fire safety codes.
