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: In contact with the flame of the gas burner, the test substance emitted orange sparks and turned into a black/light green residue. After removal of the ignition source, no propagation of combustion of the test substance 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.

Applicant's summary and conclusion

Interpretation of results:

non flammable

Remarks:

Migrated information

Conclusions:

No propagation of combustion of the test substance along 200 mm length of the pile within 4 minutes was observed. According to the guidelines, performance of the burning rate test is not required. Based on the results obtained, the test substance is considered 'not highly flammable.'
