Applicant's summary and conclusion

Conclusions:
The Minimum Ignition Energy (M.I.E) without inductivity for the sample “Di-Pentaerythritol Standard product; Perstorp ID 0808-BHN-DIP-67470312” was determined with 10 mJ(2) Klais, O.; H. Franke; M. Glor; B. Maurer und C.-D. Walther: Vermeiden von Zundquellen als vorbeugender Explosionsschutz,

Assessment criteria:
M.I.E. >=10 mJ: normally ignitable
3<=M.I.E.< 10 mJ: especially ignitable
M.I.E. < 3 mJ: extremely ignitable
Executive summary:

The Minimum Ignition Energy (M.I.E) without inductivity for the sample “Di-Pentaerythritol Standard product; Perstorp ID 0808-BHN-DIP-67470312” was determined with 10 mJ<M.I.E.<30 mJ. Therefore, the dust is specified according to the literature (2) as “normally ignitable”.
