Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- other: SOP is based on ISO 6184 Part 1 (1985) Explosion Protection Systems, Part 1 : Method for determination of explosion indices of combustible dusts in air.
- Principles of method if other than guideline:
- 20 Litre Sphere -(Explosion Severity): Explosion severity is a measure of the maximum pressure (Pmax) and the rate of pressure increase (dP/dtmax) generated by an exploding dust cloud determined in what is known as the '20 litre sphere' apparatus
- GLP compliance:
- yes

DUST EXPLOSIVITY
Group:A
Maximum Explosion Pressure:8.5 bar

TRAIN FIRE (10cm burn):Non-combustible. (Supports localised combustion).
Applicant's summary and conclusion
- Interpretation of results:
- non explosive
- Remarks:
- Migrated information
- Conclusions:
- Dust cloud ignition produces a strong dust explosion (St 2; Kst = 255 bar mis).
Dust cloud explosions will produce high maximum pressure (Pmax = 8.5 bar).
This material is classified as a non-combustible solid and will not support propagating
combustion. It can support combustion in the vicinity of a very hot ignition source.
