What is the measurement accuracy required for SFRM thickness gauges?

The accuracy required for Spray-Applied Fire-Resistive Material (SFRM) thickness gauges is 1/16-inch. This level of precision is critical in ensuring that the fireproofing material is applied to the correct thickness, which is essential for effective fire protection and performance.

SFRMs have specific thickness requirements that must be met to provide the intended level of fire resistance. If the material is applied too thickly or too thinly, it may result in compromised structural integrity, leading to insufficient protection of the structural elements in a fire scenario. Therefore, using a gauge that can measure to an accuracy of 1/16-inch ensures that the application meets the performance specifications outlined in building codes and standards.

Higher accuracy requirements like 1/32-inch may not be mandated, but a measurement of 1/16-inch balances precision with practicality for field application. It allows for slight variations that may occur during application while still ensuring safety and compliance with fire protection standards.
