（MIE-D1.2)MINIMUM IGNITION ENERGY OF DUST DISPERSIONS

The Minimum Ignition Energy (MIE) of a combustible substance is the lowest value of the electrical energy stored in a capacitor which upon discharge is just sufficient to ignite a fuel/air mixture at atmospheric pressure and room temperature. The MIE of dust dispersions is one of the key parameters for an assessment of the hazard situation in plants with dust appearance establishing the extent and, hence, the cost of protective measures.

APPLICATION

The MIE-D 1.2 (Minimum Ignition Energy Tester) is used for the measurement of the minimum amount of energy required in a normal atmosphere - within a specified dust dispersion of a substance which-will result in an ignition. The MIE-D 1.2 is an essential part of a standard set of tests used for the assessment of potential industrial plant hazards and by certifying bodies, universities and other research organizations to characterize the hazards of dusts.

COMPLIANCE

•   Minimum ignition energy of dust dispersions according to EN 13821
