The lowest energy value of a high-voltage capacitor discharge required
to ignite the most ignitable dust/air mixture, normally performed at
atmospheric temperature and pressure. MIE
with inductance refers to protracted capacitor discharges which are
generally clearly more incendive than purely capacitive discharges (MIE
without inductance). However,
MIE without inductance is more representative of most electrostatic
is conducted in accordance with ASTM E 2019: Standard Test Method for
Minimum Ignition Energy of a Dust Cloud in Air.
Based on the Minimum Ignition Energy (MIE) data i.e :
With Inductance = 1000 mJ < MIE
Without Inductance = 100 mJ < MIE < 300 mJ
Potential ignition sources include: large spark and
propagating brush discharges, and hot surfaces >320°C.
