Results and discussion
Flammable solids
- Key result
- Test procedure:
- burning rate test: preliminary screening test
- Remarks on result:
- other: The substace could be ignited but it did not propagate combustion by burning with flame along 200 mm of the powder train in less than 2 minutes or 4 minutes.
Any other information on results incl. tables
The substance could be ignited by a flame. The burning time over a distance of 100 mm was 305 seconds. The calculated burning time over a distance of 200 mm is 610 seconds (approx. 10 minutes). As this was significantly longer than 4 minutes, no further tests were performed.
Applicant's summary and conclusion
- Interpretation of results:
- other: not classified based on GHS or CLP criteria
- Conclusions:
- The substance is not a flammable solid.
- Executive summary:
The preliminary test according to EC A.10 was performed and the test substance was found to be not "highly flammable" according to the criteria of the directive.
Since no propagation of combustion along 200 mm of the powder train within 2 minutes was seen in the EC A.10 test, EC A.10 study is similar to UN Test N.1 for this substance. The substance is not a flammable solid.
