Results and discussion

Flammable solids
Test procedure:
burning time (test type not further specified)
Remarks:
or specified in description of method (migrated information)
Remarks on result:
other: No burning in contact with flame for 20 minutes
Pyrophoric solids
Test procedure:
ignition time on contact with air
Remarks:
Ignition on contact with air refers to either Pyrophoric solids or Pyrophoric liquids depending on physical state (migrated information).
Remarks on result:
no ignition on contact with air (not further specified)
Remarks:
corresponding to 'no' in migrated source record.
Pyrophoric liquids
Test procedure:
ignition time on contact with air
Remarks:
Ignition on contact with air refers to either Pyrophoric solids or Pyrophoric liquids depending on physical state (migrated information).
Remarks on result:
no ignition on contact with air (not further specified)
Remarks:
corresponding to 'no' in migrated source record.

Any other information on results incl. tables

No independent combustion of the dust layer occured.

At contact with the flame of a natural gas burner a  local red glowing of the dust particles in the effective range of the flame occured. The glowing particles went out after removing of the ignition source.

Also at conact with a glowing platinum wire of approximately 1000°C over at lease 5 minutes, no glowing could be observed.

Applicant's summary and conclusion

Conclusions:
The study is of good quality and concludes that the sample is not flammable
Executive summary:

The study is of good quality and concludes that the sample is not a readily combustible solid of class 4.1.
