Results and discussion
- Results:
- The minimum ignition energy (with inductor in the discharge circuit) of Methylen epoxide
pivalate (batch 53533015, mean particle size = 193.3 ¿m) is:
Emin : 62 mJ
Applicant's summary and conclusion
- Executive summary:
Minimum ignition energy with inductor* in the discharge circuit:
Emin = 62 mJ
The distance between the electrodes was approx. 6 mm. The sample was tested as received. The
mean of particle size was M = 193.3 ¿m. 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=100 mJ and E=30 mJ are possible
in this energy range. The result for Emin is calculated via statistical evaluation of the single
experiments (Emin, calculated = 62 mJ).
*) Method according to VDI
Commentary:
Since the mean particle size is bigger than 63 ¿m the detected minimum ignition energy of the
tested material is strongly dependent on the mean particle size. Hence the result is only valid for
batches with M ¿ 193.3 ¿m.
Dusts with a minimum ignition energy Emin < 10 mJ are considered very ignitable.
