Hot Surface Ignition

Gases, liquids, sprays and other forms of ignitable liquids and materials liberated within the environment, under certain circumstances, could encounter a hot surface. This could occur near a furnace, radiator, personal heater, within a vehicle, or in other heated environments. For example, factors which can significantly affect the performance of an ignitable liquid, when in contact with a hot surface, include the influence of the environmental conditions and the volatility of the liquid.

WHA has performed an extensive array of hot surface ignition tests, which have lead to a comprehensive understanding of the dynamics required to promote a hot surface ignition. Using a variety of standardized tests proposed by ASTM and other international standards, WHA has developed test methodologies which can be applied to a specific set of conditions for evaluating the probability of combustion as a result of coupling an ignitable medium with a hot surface.
