TSU is testing contactless fire resistance of building materials
Staff of the TSU Faculty of Mechanics and Mathematics has proposed an original contactless method for testing the fire resistance of wooden structures and building materials. Various wood construction materials (oriented strand board, plywood, and chipboard) covered with flame retardants were taken for the experiments. The results will be used in the development of fire hazard test methods. The new methodology and related software were presented at an international seminar in Saint Petersburg.
In the experiments, the scientists directed a constant stream of heat from the radiator to the sample and, at the same time, fixed the moment of ignition - the appearance of a flame on the surface. For testing the method of infrared diagnostics (when studying the ignition characteristics), they took the flame retardants available on the market.
