Results and discussion

Flammable solids
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

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The test substance is not highly flammable by ignition. The test was performed in accordance with EC A.10 of Annex V of 67/548/EEC and following United Nations Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria.
Executive summary:

The flammability of the test material has been investigated according to EC A.10 and UN N.1 methods. The preliminary screening test did not show any propagation of combustion of the test substance along 200 mm length of the pile within 2 minutes. Performance of the definitive burning rate test is not required. Based on the results obtained, the test substance is considered ‘not highly flammable’.
