Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- other: VDI 2263-1
- Principles of method if other than guideline:
- The test for dust explosibility was performed in the modified Hartmann apparatus as screening test according to VDI 2263-1. A weighed amount of the product was charged to a cylindrical glass tube of 1.2 P. The product was dispersed by an air blast. Dust concentrations of approximately 440 and 1000 g/m3 were tested. A continuous spark was used as ignition source to ignite the dust/air-mixtures. A propagation of the flame from the ignition source was considered as ignition.

Results and discussion
Any other information on results incl. tables
The dust could be ignited with a continuous spark as ignition source in the Hartmann apparatus.
Applicant's summary and conclusion
- Interpretation of results:
- other: The test item is dust explosible.
- Conclusions:
- The dust could be ignited with a continuous spark as ignition source in the Hartmann apparatus.
- Executive summary:
In a glove box (inert gas: nitrogen) the aliquots for the test were filled into sealable bottles. Shortly before each test started one bottle was opened and the sample was put into the Hartmann tube. Within a maximum of 10 seconds the test was finished.
The dust could be ignited with a continuous spark as ignition source in the Hartmann apparatus.
The test item is dust explosible.
