Results and discussion

Flammable solids
Key result
Test procedure:
burning rate test: preliminary screening test
Burning time:
1 s
Remarks on result:
other: substance does ignite but does not propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 (or 4) minutes test period

Any other information on results incl. tables

The flame of the gas burner did ignite the test item pile. The test item melted, burned with an orange flame and turned into a brown and black residue. White smoke was observed. After removal of the ignition source, the flame extinguished after 1 second and no propagation of combustion was observed.

Applicant's summary and conclusion

Interpretation of results:
other: not classified based on GHS or CLP criteria
Conclusions:
The substance is not highly flammable.
Executive summary:

The flammability of the substance was determined in a GLP study according to EC A.10 and UN Test N.1.

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 the 4 minutes test period (CLP), or within 2 minutes (GHS).

The substance is concluded to be not highly flammable/not a readily combustible solid.
