Results and discussion

Results:
The minimum ignition energy (with inductor in the discharge circuit) of Dipivalate (batch
52542501, mean particle size = 4.7 μm) is:
Emin : 1 mJ

Applicant's summary and conclusion

Executive summary:

Minimum ignition energy with inductor* in the discharge circuit: Emin = 1 mJ The distance between the electrodes was approx. 6 mm. The sample was tested as received. The mean of particle size was M = 4.7 μm. The experimental setup was checked with niacinamide as a reference substance within the last four weeks. This test showed the operability of the apparatus. Due to the design of the apparatus only measurements with E=3 mJ and E=1 mJ are possible in this energy range. The result for Emin is calculated via statistical evaluation of the single experiments (Emin, calculated = 1.3 mJ).

Commentary: Dusts with a minimum ignition energy Emin < 10 mJ are considered very ignitable
