The test of gypsum board frame by magnetic method in the performance of fire-technical examination

The article considers possibilities of applying magnetic method to test the samples of metal profiles frame used for fastening of gypsum boards to surfaces in order to determine the coercive force, the magnitude of which makes possible to evaluate the thermal damage of the samples heat-affected in the fire. The obtained results indicate the possibility of using magnetic methods to examine metal frame for gypsum boards in locating the body of fire.
