Results and discussion

Flammable solids
Key result
Test procedure:
burning rate test: preliminary screening test
Remarks on result:
other: The substance does ignite but does not propagate combustion either by burning with flame or smouldering along 200 mm of the powder train in less than 2 minutes.

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:

A GLP study according to UN Test N.1 was performed. In the preliminary screening test, the substance does ignite but does not propagate combustion either by burning with flame or smouldering along 200 mm of the test item pile within 2 minutes. The substance melted in contact with the flame. The substance is concluded to be not a flammable solid.
