- Remarks on result:
- other: burning index BZ 5
- Remarks:
- burning with flame or spark generation
- Key result
- Test procedure:
- burning rate test: preliminary screening test
- Burning time:
- > 120 s
- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- Combustion Number (BZ) 5 was determined, the burning rate was > 120 s.
Therefore, the substance has not to be classified as flammable solid according to Regulation (EC) No 1272/2008. - Endpoint:

Referenceopen allclose all
Propagation of combustion with a flame was observed when an ignition source (flame or hot wire, 2 min) was applied at ambient temperature. The product did not melt.
The combustion behaviour of the product at ambient temperature is characterized by the burning index BZ 5 (burning with flame or spark generation)
Due to the fact that propagation of the combustion was observed the burning rate need to be determined. In the preliminary test the flame extinguished after a distance of max. 2 cm reproducibly. Therefore, the main test need not to be conducted.
Local burning without propagation of combustion was observed when an ignition source (flame or hot wire, 2 min) was applied at ambient temperature. The product did not melt.
The combustion behaviour of the product at ambient temperature is characterized by the burning index BZ 3 (localized compustion or glowing with practically no spreading). The same behaviour was recorded in the test conducted at 100°C.
Due to the fact that propagation of the combustion was not observed the burning rate did not need to be determined.
Description of key information
Key value for chemical safety assessment

nanoform: BZ 3, localized combustion with practically no spreading
Justification for classification or non-classification
The substances have not to be classified as flammable solids according to Regulation (EC) No 1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
