Key result
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

In the preliminary screening test, the test flame was applied for over two minutes. The heated part of the sample melted after about 20 seconds.

When the test flame was removed, the area affected by the flame melted. It was observed generation of grey smoke. No propagation was observed. The melted sample when it cooled formed a light brown crust about 2 mm thick. The preliminary screening test was performed in duplicate and similar observations were obtained in both tests.

Interpretation of results:
not classified based on GHS criteria
According to test method A.10, Formononetin should not be considered as readily flammable.
