- Ignition produced an orange flame and grey smoke
- The minimum dust cloud ignition temperature of the test substance has been determined to be 400°C
Applicant's summary and conclusion
- Conclusions:
- The minimum temperature of a hot surface that will result in ignition of a dust cloud of the substance under specified test conditions, the Minimum Ignition Temperature (“MIT”) value of a dust cloud of the substance, was determined in a GLP-compliant study in accordance with BS EN 50281-2-1 (1999). The MIT value was determined to be 400°C.
