Results and discussion

Flammable solids
Key result
Test procedure:
other: burning index according to VDI 2263
Remarks on result:
other: burning index BZ 1
Remarks:
no ignition

Any other information on results incl. tables

The product showed no reaction when an ignition source (flame or hot wire) was applied at ambient temperature. A propagation of the combustion was not observed. The product did not melt.

The combustion behaviour of the product at ambient temperature is characterized by the burning index BZ 1 (no ignition).

Due to the fact that no propagation of the combustion was observed the burning rate had not to be determined.

Applicant's summary and conclusion

Interpretation of results:
not classified based on GHS criteria
Conclusions:
Combustion Number (BZ) 1 was determined. Therefore, the substance has not to be classified as flammable solid according to Regulation (EC) No 1272/2008.
