Applicant's summary and conclusion

Interpretation of results:
non explosive
Remarks:
Migrated information
Conclusions:
Hexagonal boron nitride dust is non explosive in concentrations between 250 and 3000 g/m3 in the 20L sphere with 5000 J chemical ignitor. Therefore, it can be concluded that hexagonal boron nitride is a non explosive substance.
