What is the required measurement increment for the dry weight of Spray-Applied Fire-Resistant Materials (SFRM) during density testing?

The requirement for measuring the dry weight of Spray-Applied Fire-Resistant Materials (SFRM) during density testing is set at an increment of 0.1g. This precision is crucial in ensuring that the density of the fireproofing material is accurately assessed, as density is a significant factor in determining the material's effectiveness and compliance with fire safety standards.

Using a measurement increment of 0.1g allows for a sufficiently detailed analysis, ensuring that small variations in the material's weight can be detected and accounted for. This level of accuracy is essential in quality control processes, where even minor deviations from the specified density can affect the performance of the fireproofing system.

By establishing this standard, industry practices ensure that the SFRM meets the necessary criteria for fire resistance, thus contributing to the overall safety and integrity of the structure being protected.
