Vergleichende Analyse der thermischen Beanspruchungs intensitäten bei normativen Raumbrandversuchen

Comparative analysis of thermal exposure conditions in standard room fire tests.

Various standards exist worldwide that describe room fire tests for determining the reaction to fire behaviour of wall and ceiling products under end-use conditions. The test methods differ with respect to the room geometry, the ventilation conditions and the type and heat output of the ignition source. Numerical simulations were performed using the CFD code FDS to comparatively analyse the resulting thermal exposure conditions for selected test rooms. The simulation results exhibit considerable differences between the analysed test methods, which may lead to inconsistent product assessments.
