What is the limit for the bond strength test method for SFRM products described in Technical Manual 12-A?

The bond strength test method for Spray-Applied Fire-Resistive Materials (SFRM) products, as outlined in Technical Manual 12-A, specifies that the limit for the bond strength should be 1,146 psf. This figure is significant as it helps ensure the performance and reliability of fireproofing materials under service conditions. A bond strength of this value indicates that the product has been tested to withstand certain stresses without delaminating or failing, which is crucial in building safety and compliance with fire safety regulations. Adhering to this standard ensures that the application of SFRM maintains its integrity when exposed to fire, thereby protecting structural elements adequately. Understanding this bond strength requirement is essential for professionals involved in the application and inspection of fireproofing materials, as it contributes to the overall effectiveness of fire protection systems in construction.
