Determination of the Spontaneous Ignition Behaviour of Dust Accumulations
Also Known As:
The DIN EN 15188 standard provides analysis and evaluation procedures for determining the self-ignition temperatures (TSI) of combustible dusts or granular materials. The standard specifies the use of hot storage experiments in ovens of constant temperature to determine the TSI as a function of volume.
This standard is applicable to solid materials that exhibit a linear correlation between the logarithm of the volume to surface area ratio (lg V/A) and the reciprocal self-ignition temperature (1/TSI), where TSI is measured in Kelvin. It is not limited to only oxidatively unstable materials but can be applied to any solid substance that meets this correlation.
However, it is important to note that this standard does not cover the ignition of dust layers or bulk solids under aerated conditions, such as those found in a fluid bed dryer. It also excludes dusts classified as recognized explosives, pyrophoric materials, and substances that do not require atmospheric oxygen for combustion. The standard advises consulting experts if there are doubts about whether a dust falls under the category of recognized explosives or exhibits similar self-ignition behavior during thermal decomposition.
