Cone calorimeter tests on FR treated Norway spruce, Comparison of different fire retardant products for timber structures

Fire retardants are effective in reducing different reaction to fire parameters of wood such as the ignitability, the heat release, the burning rate and the flame spread. This paper discusses the different mechanisms of fire retardant products as pressure impregnated wood, non-intumescence surface coatings and intumescence coatings on Norway spruce (Picea abies). The tests were performed by using the cone calorimeter test. The comparison of the investigated products will describe the mechanisms of action to reduce combustion by using the heat release rate of 25 kW/m² and 50 kW/m² and the standard IS0 834 test curve. As result information on the ignition time, the heat release rate, the mass loss and the temperature profile over the material thickness will be presented in this paper

Performance of different fire retardant products applied on Norway spruce tested in a Cone calorimeter

On the European market there are several fire retardant products available, which reach class B in the European classification system. The producers promise their fire retardants are effective in reducing different reaction to fire parameters of wood such as the time to ignition, the mass loss rate, the heat release rate, the total heat release, the charring rate and the flame spread. This paper discusses the performance of fire retardant products as pressure impregnated wood, non-intumescence surface coatings and intumescence coatings on Norway spruce (Picea abies). The investigations are performed by using a cone calo- rimeter test according to ISO 5660. The thermal exposures of the investigations are 50 kW/m2 and the standard IS0 834 test curve. As result information about the heat release rate, the mass loss rate and the total heat release for duration of 900 seconds will be presented in this paper
