Describe the circumstances in which the product burns and spreads the flame

Once the combustion of the product begins, it’s necessary to evaluate the conditions favouring this combustion and those helping the flame propagation deriving from the product to the surrounding elements. Two parameters are important for the combustion and the propagation: the heat flow that develops in the scenario under test and the ventilation conditions (quantity, direction and composition of the air flow that runs through the scenario). These two parameters should be characterized only if they reasonably influence the flame propagation and combustion in a defined system.
