Description of key information
Determination of the Minimum Ignition Energy (MIE) under standardised conditions (milling and sieving at size < 63 um) showed a high susceptibility to ignition. Determination on standard product as is (without size reduction) indicate also high sensitivity to ignition (dust explosivity potential).
MIE: 1-3 mJ (commercial grade, milled and sieved to achieve a homogeneous particle size of less than 63 um according to EN standard 13821)
MIE: 8-10 mJ (commercial grade as is, majority of particles > 100 um)
Additional information
The results of 3 different studies investigating the Minimum Ignition Energy of dust/air mixtures to assess the dust explosive potential (or combustible dust hazard) for the purpose of Process Safety measures in the production sites are summarized below:

*The current EN standard requires assessing the MIE on samples after reduction by milling and sieving of particles to sizes less than 63 um.
(^) due to the localization of the sampling, the size is not representative of the commercial product, but rather a fraction of broken particules produced during the drying process.
These results indicate a high sensitivity to static charges, even for the products as is.
