Results and discussion

Results:
Minimum Ignition Energy (MIE):

With Inductance = 1000 mJ < MIE
Without Inductance = 100 mJ < MIE < 300 mJ

Comments: The MIE with inductance is typically lower or equal to the than MIE without inductance. This is an unusual case where the MIE without inductance is lower than the MIE with inductance.

Any other information on results incl. tables

MIE : 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 sparks. Testing is conducted in accordance with ASTM E 2019: Standard Test Method for Minimum Ignition Energy of a Dust Cloud in Air.

Applicant's summary and conclusion

Conclusions:
Potential ignition sources include: large spark and propagating brush discharges, and hot surfaces >320°C.
Executive summary:

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.
