during the life of the structure, as well as upon its satisfactory performance under fire tests.
This test method measures the behavior of SFRM when subjected to deflection and evaluates such phenomena as spalling and delamination under bending stress. It is an indication of the ability of SFRM to remain in place and resist removal during anticipated service conditions.
1. Scope
1.1 This test method covers a procedure for determining the effect of deflection on sprayed fire-resistive material
