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 test substance only showed decomposition when an ignition source was applied at ambient temperature. No propagation of the combustion was observed. The substance did not melt.
The combustion behaviour of the test substance is characterized by burning class number (BZ = Brennzahl) 1: no ignition (definition according to Directive VDI 2263, Part 1)
Determination of burning rate was not required
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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
