Test procedure:
burning rate test: preliminary screening test
Burning time:
36 s
Moisture (wt %):
0.73
Remarks on result:

Key result
Test procedure:
burning rate test over 100 mm length
Burning time:
< 45 s
Moisture (wt %):
0.73

In the preliminary test, the pile ignited and burnt with a blue/orange flame. Combustion was propagated over the 200 mm in 36 seconds.

Interpretation of results:
Category 2 (flammable solids) based on GHS criteria
Conclusions:
The test material has been determined to be highly flammable as it propagated combustion over the 100 mm of the main test in under 45 seconds.
Executive summary:

The flammability test was performed following EC-method A.10. In the preliminary test, the pile ignited and burnt with a blue/orange flame. Combustion was propagated over the 200 mm in 36 seconds. In the main study, the test material has been determined to be highly flammable as it propagated combustion over the 100 mm of the main test in under 45 seconds. In addition, tests A.12 and A.13 were not conducted, as based on the chemical structure, the test item does neither react with water nor evolve any flammable gases in contact with (humid) air.
