Results and discussion
Flammable solids
- Test procedure:
- burning time (test type not further specified)

- Remarks:
- BZ1 (no ignition)
Applicant's summary and conclusion
- Interpretation of results:
- non flammable
- Conclusions:
- Combustion Number 1 can be assigned to the substance (no ignition)
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 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 melted.
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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
