Reaction to fire testing

Understanding CombustibilityThere 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?
