What is the minimum bond strength specified before conducting SFRM tests?

• A. 50 lbs per sq. ft.
• B. 100 lbs per sq. ft.
• C. 150 lbs per sq. ft.
• D. 200 lbs per sq. ft.

Answer: (C)

The minimum bond strength specified before conducting Spray-Applied Fire-Resistive Materials (SFRM) tests is 150 lbs per sq. ft. This standard is essential because it ensures that the fire-resistive materials adhere properly to the substrate, providing the necessary fire protection in the event of a fire. Adequate bond strength is critical in maintaining the integrity of the fire-resistant coating, as it prevents delamination and potential failure during exposure to heat or fire conditions. The 150 lbs per sq. ft. requirement is a benchmark that ensures consistency in performance and safety across different applications of SFRM.
