What is the minimum reading capability required for SFRM thickness gauges?

The minimum reading capability required for Spray-Applied Fire-Resistive Materials (SFRM) thickness gauges is 1/16-inch. This level of precision is essential because it ensures that the applied fireproofing material adheres to the specified thickness requirements laid out in the building codes and project standards.

Measurement accuracy is crucial for the effectiveness of fireproofing materials, as insufficient thickness can compromise the material's fire-resistance rating, leading to potential safety hazards and code violations. By requiring a gauge that can measure to 1/16-inch, inspectors can ensure that they are accurately assessing the application of SFRM, thereby confirming that it meets performance standards necessary for fire safety compliance.

This capability prevents over-application or under-application of the SFRM, ensuring uniformity and integrity in fireproofing protecting structural elements during a fire incident.
