This European Standard specifies analysis and evaluation procedures for determining self-ignition
temperatures (TSI) of combustible dusts or granular materials as a function of volume by hot storage
experiments in ovens of constant temperature. The specified test method is applicable to any solid material for
which the linear correlation of lg (V/A) versus the reciprocal self-ignition temperature 1/TSI (with TSI in K) holds
(i.e. not limited to only oxidatively unstable materials).
This European Standard is not applicable to the ignition of dust layers or bulk solids under aerated conditions
(e.g. as in fluid bed dryer).
This European Standard should not be applied to dusts like recognised explosives that do not require
atmospheric oxygen for combustion, nor to pyrophoric materials.
NOTE Because of regulatory and safety reasons “recognised explosives” are not in the scope of this European
Standard. In spite of that, substances which undergo thermal decomposition reactions and which are not “recognised
explosives” but behave very similarly to self-ignition processes when they decompose are in the scope. If there are any
doubts as to whether the dust is an explosive or not, experts should be consulted.
