Ignition

In some cases, it is possible to classify untreated wood-based products without further testing as long as these products meet the requirements set out in the relevant harmonised technical specification.

There are four recognised stages in the development of any fire: Ignition, Spread and Growth, Flash point into a fully developed fire and Eventual Decay. During the early stages, when a fire is still becoming established, the important factors are: Ignitability, Spread of Flame, Smoke Production and Flaming droplets.
