Any other information on results incl. tables

The test substance burned after contact with an ignition source (flame or hot platinum wire).

The combustion class number BZ 5 (spread of an open fire) was assigned.

The test substance did not show liquefaction.

The burning rate was determined.

Preliminary test result: Burning time of 133 s (2 min 13 s) for 200 mm.

Main test result: The lowest burning time was 80 s for 100 mm.

The combustion of the test substance could be stopped by wetting the powder strip with water.

Applicant's summary and conclusion

Interpretation of results:
non flammable
Remarks:
Migrated information
Conclusions:
The test substance showed spread of an open fire (combustion class number BZ 5) and a burning time of 80 s for a powder strip of 100 mm.
The test substance is not a flammable solid according to GHS/CLP and UN transport regulations class 4.1.
Executive summary:

The flammability of the test substance was determined by a combustion class number test according to VDI 2263, sheet 1.

The test substance showed spread of an open fire (combustion class number BZ 5) and a burning time of 80 s for a powder strip of 100 mm. Classification as a flammable solid is not required.
