Thermal properties of intumescent passive fire protection materials
The purpose of a fire engineering simulation is to predict a thermal response, and a structural response, of a loaded structural element. Intumescent materials have been applied for a long time to protect equipment and structure against fire exposure in chemical and petrochemical industry. In need of optimising use of protection, simulation by use of computer codes has been more and more applied. These codes are dependent on reliable property data as input to the code; data that are partly highly unreliably and partly non existent. The reason is that there is not yet developed a test method for testing of intumescing materials that can give reliable property data applicable in computer codes. The main purpose of the new test method is to build a bridge between laboratory tests and simulation systems applied in engineering. For that reason, the test method must include both physical tests and simulations, and the results must be comparable. A test method for determination of thermal conductivity is proposed. The principle of the proposed test stand is shown. The experience from use of the proposed test method is demonstrated. The method has potential to give required material property data for application in engineering simulations. It will nevertheless need a better heating system.
