Results and discussion
Flammable solids
- Key result
- Test procedure:
- burning rate test: preliminary screening test
- Remarks on result:
- substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period
Any other information on results incl. tables
Preliminary test
Assay N°1
The test item became incandescent but neither propagation nor ignition was observed.
Assay N°2
The same observations as for the first assay were recorded.
Based on the results of the preliminary test, no main test was performed.
Applicant's summary and conclusion
- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- The flammability of the test item was investigated according to the UN N.1 test method in compliance with GLP. According to the results of the preliminary test (no ignition, no propagation), the substance does not need to be classified as a flammable solid of Division 4.1 and is not assigned to any packing group.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
