Reaction to fire testing
There are four recognised stages in the development of any fire: Ignition, Spread and growth, ‘Flashover’ into a fully developed fire and Eventual decay. During the early stages, when a fire is still becoming established the important factors are
- • Ignitability – how readily will a material ignite and catch fire?
- • Spread of flame – once ignited, how quickly will flames spread across the surface of that material?
- • Heat release – once alight, how much heat energy will be generated by the burning material, which will contribute to the further growth of the fire?
- • Flaming droplets – will the burning material disintegrate and produce burning droplets or debris which might fall onto and ignite other surfaces?
