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

Any other information on results incl. tables

In contact with the ignition source, the test item smoldered and the surface area carbonized. Below the surface the test item remained unaltered. The test item could not be ignited with a flame during the preliminary test (contact time of about 2 minutes).

Therefore, no main test was performed.

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The test item could not be ignited with a flame during the preliminary test. Thus, the substance has not to be classified as flammable solid according to Regulation (EC) 1272/2008
