Any other information on results incl. tables

The heap of powder showed a spread of an open fire. The combustion class number BZ 5 was assigned. The burning time for 100 mm was determined to be above 120 s and the burning rate was below 0.83 mm/s.

Applicant's summary and conclusion

Interpretation of results:
non flammable
Remarks:
Migrated information
Conclusions:
The combustion class number BZ 5 was assigned. The burning time for 100 mm was determined to be above 120 s and the burning rate was below 0.83 mm/s. The test substance is not a highly flammable solid according to Regulation (EC) No 1272/2008.
Executive summary:

The flammability of the test substance was evaluated by determination of the combustion class number ("Brennzahl" BZ) and the burning time and rate for a powder line of 100 mm length. The combustion class number BZ 5 was assigned. The burning time for 100 mm was determined to be above 120 s and the burning rate was below 0.83 mm/s
