What is the precision measurement for dry weight in SFRM density testing?

The precision measurement for dry weight in Spray-Applied Fire-Resistive Materials (SFRM) density testing is 0.1 grams. This level of precision is critical in accurately determining the density of fireproofing materials because even small variations in weight can significantly affect the calculated density, which directly influences the fire-resistive qualities and overall performance of the material. A measurement precision of 0.1 grams ensures that the testing process is sufficiently sensitive to capture these important variations, thereby providing reliable data for material quality control and compliance with safety standards.
