Applicant's summary and conclusion

Interpretation of results:
non flammable
Conclusions:
Combustion Number 3 can be assigned to the substance (localized combustion or glowing with practically no spreading)

UN transport regulation: The substance does not have to be classified as a “readily combustible solid”, class 4.1, of the transport regulations.
EU-GHS/CLP: The substance does not have to be classified as a “flammable solid”.
Regulation (EG) 440/2008 (test methods for REACH): The substance does not have to be classified as a “highly flammable solid”.
Executive summary:

The substance was tested for flammability according to VDI 2263 sheet 1.

The product showed a local glowing fire 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 3 (localized combustion or glowing with practically no spreading).

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