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: Taking into account the results obtained during the preliminary test, no main test was performed.
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

At the start of the test, the test item was a fine black powder. The test item became incandescent in contact of the gas burner flame. Neither ignition, nor propagation was observed.

The same observations were recorded for the second assay.

Applicant's summary and conclusion

Interpretation of results:
