Which of the following criteria must be met for acceptance of SFRM?

For the acceptance of Spray-Applied Fire Resistive Material (SFRM), it is essential that all acceptance criteria must be met. This requirement ensures that the SFRM conforms to safety standards and performance specifications necessary for effective fire protection. Meeting all criteria promotes consistency and reliability in the application, ensuring that the material will perform as intended in the event of a fire.

If only a portion of the tests were required to be met or if the criteria were flexible, it could result in inadequate fire resistance, which poses a significant risk to safety. Visual inspections alone would not be comprehensive enough to confirm the effectiveness of the material, as more detailed evaluations are necessary to assess the physical properties and fire performance capabilities. Variability in thickness across samples could lead to inconsistent fire resistance, undermining the protective intent of the fireproofing application. Therefore, requiring that all acceptance criteria be satisfied aligns with the highest standards for safety and performance of fireproofing systems.
