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 propagation of combustion along 200 mm length of the powder train within 2 or within 4 minutes was observed.
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.
Substances / mixtures which in contact with water emit flammable gases
Remarks on result:
no reaction with water observed
Remarks:
corresponding to 'no' in migrated source record.

Any other information on results incl. tables

The flame of the gas burner did ignite the test substance pile. The test substance glowed, burned with a blue yellow flame and turned into a grey-black residue. Grey smoke was observed. After removal of the ignition source, the flame extinguished immediately and no propagation of combustion was observed.

Applicant's summary and conclusion

Interpretation of results:
other: 'not highly flammable' by ignition
Conclusions:
In a GLP-compliant study performed in accordance with UN-MTC Section 33.2.1 (Test N.1) and EC.A10, the substance has been determined to be 'not highly flammable'.
