Determination of the Spontaneous Ignition Behaviour of Dust Accumulations
Also Known As:
DIN EN 15188 is a European standard that lays out the procedures for determining the spontaneous ignition behavior of dust accumulations. Specifically, the standard focuses on determining the self-ignition temperatures (TSI) of combustible dusts or granular materials. The TSI is determined through hot storage experiments in ovens of constant temperature.
The test method outlined in DIN EN 15188 is applicable to any solid material that exhibits a linear correlation between the logarithm of the volume-to-surface-area ratio (lg (V/A)) and the reciprocal self-ignition temperature (1/TSI), with TSI measured in Kelvin. Importantly, the standard is not limited to oxidatively unstable materials but can be applied to any solid material that fits the correlation criteria.
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 in a fluid bed dryer. Additionally, it does not apply to dusts classified as recognized explosives or pyrophoric materials, as these require separate safety considerations. If there are doubts about whether a dust is an explosive or not, it is recommended to consult with experts.
